The coyote (''Canis latrans'') is a
Coyote males average in weight, while females average , though size varies geographically. Northern subspecies, which average , tend to grow larger than the southern subspecies of Mexico, which average . Total length ranges on average from ; comprising a tail length of , with females being shorter in both body length and height. The largest coyote on record was a male killed near Afton, Wyoming, on November19, 1937, which measured from nose to tail, and weighed . Scent glands are located at the upper side of the base of the tail and are a bluish-black color.
The color and texture of the coyote's fur vary somewhat geographically. The hair's predominant color is light gray and red or fulvous, interspersed around the body with black and white. Coyotes living at high elevations tend to have more black and gray shades than their desert-dwelling counterparts, which are more fulvous or whitish-gray. The coyote's fur consists of short, soft underfur and long, coarse guard hairs. The fur of northern subspecies is longer and denser than in southern forms, with the fur of some Mexican and Central American forms being almost hispid (bristly). Generally, adult coyotes (including coywolf hybrids) have a sable coat color, dark neonatal coat color, bushy tail with an active supracaudal gland, and a white facial mask. Albinism is extremely rare in coyotes. Out of a total of 750,000 coyotes killed by federal and cooperative hunters between March 1938, and June 1945, only two were albinos.
The coyote is typically smaller than the gray wolf, but has longer ears and a relatively larger Neurocranium, braincase, as well as a thinner frame, face, and muzzle. The scent glands are smaller than the gray wolf's, but are the same color. Its fur color variation is much less varied than that of a wolf. The coyote also carries its tail downwards when running or walking, rather than horizontally as the wolf does.
Coyote tracks can be distinguished from those of dogs by their more elongated, less rounded shape. Unlike dogs, the upper canines of coyotes extend past the mental foramina.
At the time of the European colonization of the Americas, coyotes were largely confined to open plains and arid regions of the western half of the continent. In early post-Columbian historical records, determining whether the writer is describing coyotes or wolves is often difficult. One record from 1750 in Kaskaskia, Illinois, written by a local priest, noted that the "wolves" encountered there were smaller and less daring than European wolves. Another account from the early 1800's in Edwards County, Illinois, Edwards County mentioned wolves howling at night, though these were likely coyotes. This species was encountered several times during the Lewis and Clark Expedition (1804–1806), though it was already well known to European traders on the upper Missouri River, Missouri. Meriwether Lewis, writing on 5 May 1805, in northeastern Montana, described the coyote in these terms:
The coyote was first scientifically described by naturalist Thomas Say in September 1819, on the site of Lewis and Clark's Council Bluffs, up the Missouri River from the mouth of the Platte during a Stephen Harriman Long#1817-23 expeditions up the Missouri and Platte Rivers, government-sponsored expedition with Major Stephen Harriman Long, Stephen Long. He had the first edition of the Lewis and Clark journals in hand, which contained Biddle's edited version of Lewis's observations dated 5 May 1805. His account was published in 1823. Thomas Say, Say was the first person to document the difference between a "''prairie wolf''" (coyote) and on the next page of his journal a wolf which he named ''Canis nubilus'' (Great Plains wolf). Say described the coyote as:
In 1993, a study proposed that the wolves of North America display skull traits more similar to the coyote than wolves from Eurasia. In 2010, a study found that the coyote was a lineage (genetic)#Basal lineage, basal member of the clade that included the Tibetan wolf, the Dog, domestic dog, the Mongolian wolf and the Eurasian wolf, with the Tibetan wolf diverging early from wolves and domestic dogs.
In 2016, a Whole genome sequencing, whole-genome DNA study proposed, based on the assumptions made, that all of the North American wolves and coyotes diverged from a common ancestor about 51,000 years ago. However, the proposed timing of the wolf / coyote divergence conflicts with the discovery of a coyote-like specimen in strata dated to 1 Mya. The study also indicated that all North American wolves have a significant amount of coyote ancestry and all coyotes some degree of wolf ancestry, and that the red wolf and eastern wolf are highly Genetic admixture, admixed with different proportions of gray wolf and coyote ancestry.
Genetic studies relating to wolves or dogs have inferred phylogenetic relationships based on the only reference genome available, that of the Boxer dog. In 2017, the first reference genome of the wolf ''Canis lupus lupus'' was mapped to aid future research. In 2018, a study looked at the genomic structure and admixture of North American wolves, wolf-like canids, and coyotes using specimens from across their entire range that mapped the largest dataset of nuclear genome sequences against the wolf reference genome.
The study supports the findings of previous studies that North American gray wolves and wolf-like canids were the result of complex gray wolf and coyote mixing. A polar wolf from Greenland and a coyote from Mexico represented the purest specimens. The coyotes from Alaska, California, Alabama, and Quebec show almost no wolf ancestry. Coyotes from Missouri, Illinois, and Florida exhibit 5–10% wolf ancestry. There was 40% wolf to 60% coyote ancestry in red wolves, 60% wolf to 40% coyote in Eastern timber wolves, and 75% wolf to 25% coyote in the Great Lakes wolves. There was 10% coyote ancestry in Mexican wolves and the Atlantic Coast wolves, 5% in Pacific Coast and Yellowstone wolves, and less than 3% in Canadian archipelago wolves. If a third canid had been involved in the admixture of the North American wolf-like canids, then its genetic signature would have been found in coyotes and wolves, which it has not.
In 2018, whole genome sequencing was used to compare members of the genus ''Canis''. The study indicates that the common ancestor of the coyote and gray
Coyotes occasionally mate with Dog, domestic dogs, sometimes producing crosses colloquially known as "coydogs". Such matings are rare in the wild, as the mating cycles of dogs and coyotes do not coincide, and coyotes are usually antagonistic towards dogs. Hybridization usually only occurs when coyotes are expanding into areas where conspecifics are few, and dogs are the only alternatives. Even then, pup survival rates are lower than normal, as dogs do not form pair bonds with coyotes, thus making the rearing of pups more difficult. In captivity, F1 hybrid, F1 hybrids (first generation) tend to be more mischievous and less manageable as pups than dogs, and are less trustworthy on maturity than Wolfdog, wolf-dog hybrids.
Hybrids vary in appearance, but generally retain the coyote's #Description, usual characteristics. F1 hybrids tend to be intermediate in form between dogs and coyotes, while F2 hybrids (second generation) are more varied. Both F1 and F2 hybrids resemble their coyote parents in terms of shyness and intrasexual aggression. Hybrids are fertile and can be successfully bred through four generations. Melanism, Melanistic coyotes owe their black pelts to a mutation that first arose in domestic dogs. A population of nonalbino white coyotes in Newfoundland owe their coloration to a melanocortin 1 receptor mutation inherited from Golden Retrievers.
Coyotes have hybridized with wolves to varying degrees, particularly in eastern
Like the Eurasian golden jackal, the coyote is gregarious, but not as dependent on Biological specificity, conspecifics as more social canid species like wolves are. This is likely because the coyote is not a specialized hunter of large prey as the latter species is. The basic social unit of a coyote pack is a family containing a reproductive female. However, unrelated coyotes may join forces for companionship, or to bring down prey too large to attack singly. Such "nonfamily" packs are only temporary, and may consist of bachelor males, nonreproductive females and subadult young. Families are formed in midwinter, when females enter estrus. Pair bonding can occur 2–3 months before actual Copulation (zoology), copulation takes place.
The copulatory tie can last 5–45 minutes. A female entering estrus attracts males by scent marking and howling with increasing frequency. A single female in heat can attract up to seven reproductive males, which can follow her for as long as a month. Although some squabbling may occur among the males, once the female has selected a mate and copulates, the rejected males do not intervene, and move on once they detect other estrous females. Unlike the wolf, which has been known to practice both Monogamy in animals, monogamous and bigamous matings, the coyote is strictly monogamous, even in areas with high coyote densities and abundant food.
Females that fail to mate sometimes assist their sisters or mothers in raising their pups, or join their siblings until the next time they can mate. The newly mated pair then establishes a territory and either constructs their own den or cleans out abandoned American badger, badger, marmot, or skunk earths. During the pregnancy, the male frequently hunts alone and brings back food for the female. The female may line the den with dried grass or with fur pulled from her belly. The gestation period is 63 days, with an average litter size of six, though the number fluctuates depending on coyote population density and the abundance of food.
Coyote pups are born in dens, hollow trees, or under ledges, and weigh at birth. They are altricial, and are completely dependent on milk for their first 10 days. The incisors erupt at about 12 days, the canine teeth, canines at 16, and the second premolars at 21. Their eyes open after 10 days, by which point the pups become increasingly more mobile, walking by 20 days, and running at the age of six weeks. The parents begin supplementing the pup's diet with regurgitated solid food after 12–15 days. By the age of four to six weeks, when their milk teeth are fully functional, the pups are given small food items such as mice, rabbits, or pieces of ungulate carcasses, with lactation steadily decreasing after two months.
Unlike wolf pups, coyote pups begin seriously fighting (as opposed to play fighting) prior to engaging in play behavior. A common play behavior includes the coyote "hip-slam". By three weeks of age, coyote pups bite each other with less inhibition than wolf pups. By the age of four to five weeks, pups have established dominance hierarchies, and are by then more likely to play rather than fight. The male plays an active role in feeding, grooming, and guarding the pups, but abandons them if the female goes missing before the pups are completely Weaning, weaned. The den is abandoned by June to July, and the pups follow their parents in patrolling their territory and hunting. Pups may leave their families in August, though can remain for much longer. The pups attain adult dimensions at eight months and gain adult weight a month later.
When hunting large prey, the coyote often works in pairs or small groups. Success in killing large ungulates depends on factors such as snow depth and crust density. Younger animals usually avoid participating in such hunts, with the breeding pair typically doing most of the work. The coyote pursues large prey, typically hamstringing the animal, and subsequently then harassing it until the prey falls. Like other canids, the coyote Hoarding (animal behavior), caches excess food. Coyotes catch mouse-sized rodents by pouncing, whereas ground squirrels are chased. Although coyotes can live in large groups, small prey is typically caught singly.
Coyotes have been observed to kill North American porcupine, porcupines in pairs, using their paws to flip the rodents on their backs, then attacking the soft underbelly. Only old and experienced coyotes can successfully prey on porcupines, with many predation attempts by young coyotes resulting in them being injured by their prey's quills. Coyotes sometimes urination, urinate on their food, possibly to claim ownership over it.Wells, Michael C., and Marc Bekoff.
An observational study of scent-marking in coyotes, Canis latrans
" (1981). Recent evidence demonstrates that at least some coyotes have become more nocturnal in hunting, presumably to avoid humans. Coyotes may occasionally form mutualism (biology), mutualistic hunting relationships with American badgers, assisting each other in digging up rodent prey. The relationship between the two species may occasionally border on apparent "friendship", as some coyotes have been observed laying their heads on their badger companions or licking their faces without protest. The amicable interactions between coyotes and badgers were known to pre-Columbian civilizations, as shown on a jar found in Mexico dated to 1250–1300 Current era, CE depicting the relationship between the two. Food scraps, pet food, and animal feces may attract a coyote to a trash can.
Prior to the near extermination of wolves and cougars, the coyote was most numerous in grasslands inhabited by American bison, bison, pronghorn, elk, and other deer, doing particularly well in short-grass areas with prairie dogs, though it was just as much at home in semiarid areas with sagebrush and jackrabbits or in deserts inhabited by cactus, kangaroo rats, and rattlesnakes. As long as it was not in direct competition with the wolf, the coyote ranged from the Sonoran Desert to the alpine regions of adjoining mountains or the plains and mountainous areas of Alberta. With the extermination of the wolf, the coyote's range expanded to encompass broken forests from the tropics of Guatemala and the northern slope of Alaska.
Coyotes walk around per day, often along trails such as logging roads and paths; they may use iced-over rivers as travel routes in winter. They are often crepuscular, being more active around evening and the beginning of the night than during the day. However, in urban areas coyotes are known to be more nocturnal, likely to avoid encounters with humans. Like many canids, coyotes are competent swimmers, reported to be able to travel at least across water.
The coyote is ecologically the North American equivalent of the Eurasian
In areas where the ranges of coyotes and gray wolves overlap, interference competition and predation by wolves has been hypothesized to limit local coyote densities. Coyote ranges expanded during the 19th and 20th centuries following the extirpation of wolves, while coyotes were driven to extinction on Isle Royale after wolves colonized the island in the 1940s. One study conducted in Yellowstone National Park, where both species coexist, concluded that the coyote population in the Lamar River, Lamar River Valley declined by 39% following the reintroduction of wolves in the 1990s, while coyote populations in wolf inhabited areas of the Grand Teton National Park are 33% lower than in areas where they are absent. Wolves have been observed to not tolerate coyotes in their vicinity, though coyotes have been known to trail wolves to feed on their kills.
Coyotes may compete with cougars in some areas. In the eastern Sierra Nevada, coyotes compete with cougars over mule deer. Cougars normally outcompete and dominate coyotes, and may kill them occasionally, thus reducing coyote predation pressure on smaller carnivores such as foxes and bobcats. Coyotes that are killed are sometimes not eaten, perhaps indicating that these comprise competitive interspecies interactions, however there are multiple confirmed cases of cougars also eating coyotes. In northeastern Mexico, cougar predation on coyotes continues apace but coyotes were absent from the prey spectrum of sympatric jaguars, apparently due to differing habitat usages.
Other than by gray wolves and cougars, predation on adult coyotes is relatively rare but multiple other predators can be occasional threats. In some cases, adult coyotes have been preyed upon by both American black bear, American black and grizzly bears, American alligators, large Canada lynx and golden eagles. At kill sites and carrion, coyotes, especially if working alone, tend to be dominated by wolves, cougars, bears, wolverines and, usually but not always, eagles (i.e., Bald eagle, bald and golden). When such larger, more powerful and/or more aggressive predators such as these come to a shared feeding site, a coyote may either try to fight, wait until the other predator is done or occasionally share a kill, but if a major danger such as wolves or an adult cougar is present, the coyote will tend to flee.
Coyotes rarely kill healthy adult red foxes, and have been observed to feed or den alongside them, though they often kill foxes caught in traps. Coyotes may kill fox kits, but this is not a major source of mortality. In southern California, coyotes frequently kill gray foxes, and these smaller canids tend to avoid areas with high coyote densities.
In some areas, coyotes share their ranges with bobcats. These two similarly-sized species rarely physically confront one another, though bobcat populations tend to diminish in areas with high coyote densities. However, several studies have demonstrated interference competition between coyotes and bobcats, and in all cases coyotes dominated the interaction. Multiple researchers reported instances of coyotes killing bobcats, whereas bobcats killing coyotes is more rare. Coyotes attack bobcats using a bite-and-shake method similar to what is used on medium-sized prey. Coyotes, both single individuals and groups, have been known to occasionally kill bobcats. In most cases, the bobcats were relatively small specimens, such as adult females and juveniles.
Coyote attacks, by an unknown number of coyotes, on adult male bobcats have occurred. In California, coyote and bobcat populations are not negatively correlated across different habitat types, but predation by coyotes is an important source of mortality in bobcats. Biologist Stanley Paul Young noted that in his entire trapping career, he had never successfully saved a captured bobcat from being killed by coyotes, and wrote of two incidents wherein coyotes chased bobcats up trees. Coyotes have been documented to directly kill Canada lynx on occasion, and compete with them for prey, especially snowshoe hares. In some areas, including central Alberta, lynx are more abundant where coyotes are few, thus interactions with coyotes appears to influence lynx populations more than the availability of snowshoe hares.
Due to the coyote's wide range and abundance throughout North America, it is listed as Least Concern by the
Among large North American carnivores, the coyote probably carries the largest number of diseases and parasites, likely due to its wide range and varied diet. Viral diseases known to infect coyotes include rabies, canine distemper, infectious canine hepatitis, four strains of equine encephalitis, and Oral florid papillomatosis, oral papillomatosis. By the late 1970s, serious rabies outbreaks in coyotes had ceased to be a problem for over 60 years, though sporadic cases every 1–5 years did occur. Distemper causes the deaths of many pups in the wild, though some specimens can survive infection. ''Tularemia'', a bacterial disease, infects coyotes from tick bites and through their rodent and lagomorph prey, and can be deadly for pups.
Coyotes can be infected by both Demodicosis, demodectic and sarcoptic mange, the latter being the most common. Mite infestations are rare and incidental in coyotes, while tick infestations are more common, with seasonal peaks depending on locality (May–August in the Northwest, March–November in Arkansas). Coyotes are only rarely infested with Louse, lice, while fleas infest coyotes from puphood, though they may be more a source of irritation than serious illness. ''Pulex, Pulex simulans'' is the most common species to infest coyotes, while ''Ctenocephalides canis'' tends to occur only in places where coyotes and dogs (its primary host) inhabit the same area. Although coyotes are rarely host to Trematoda, flukes, they can nevertheless have serious effects on coyotes, particularly ''Nanophyetus salmincola'', which can infect them with salmon poisoning disease, a disease with a 90% mortality rate. Trematode ''Metorchis conjunctus'' can also infect coyotes.
Tapeworms have been recorded to infest 60–95% of all coyotes examined. The most common species to infest coyotes are ''Taenia pisiformis'' and ''Taenia crassiceps'', which uses cottontail rabbits as intermediate hosts. The largest species known in coyotes is ''T. hydatigena'', which enters coyotes through infected ungulates, and can grow to lengths of . Although once largely limited to wolves, ''Echinococcus granulosus'' has expanded to coyotes since the latter began colonizing former wolf ranges.
The most frequent Ascarididae, ascaroid roundworm in coyotes is ''Toxascaris leonina'', which dwells in the coyote's small intestine and has no ill effects, except for causing the host to eat more frequently. Hookworms of the genus ''Ancylostoma'' infest coyotes throughout their range, being particularly prevalent in humid areas. In areas of high moisture, such as coastal Texas, coyotes can carry up to 250 hookworms each. The blood-drinking ''Ancylostoma caninum, A. caninum'' is particularly dangerous, as it damages the coyote through blood loss and lung congestion. A 10-day-old pup can die from being host to as few as 25 ''A. caninum'' worms.
Coyote features as a trickster figure and skin-walker in the folktales of some Native Americans in the United States, Native Americans, notably several nations in the Indigenous peoples of the North American Southwest, Southwestern and Plains Indians, Plains regions, where he alternately assumes the form of an actual coyote or that of a man. As with other trickster figures, Coyote acts as a picaresque hero who rebels against social convention through deception and humor. Folklorists such as Harris believe coyotes came to be seen as tricksters due to the animal's intelligence and adaptability. After the European colonization of the Americas, Anglo-American depictions of Coyote are of a cowardly and untrustworthy animal. Unlike the gray wolf, which has undergone a radical improvement of its public image, Anglo-American cultural attitudes towards the coyote remain largely negative.
In the Maidu creation story, Coyote introduces work, suffering, and death to the world. Zuni people, Zuni lore has Coyote bringing winter into the world by stealing light from the kachinas. The Chinookan peoples, Chinook, Maidu, Pawnee people, Pawnee, Tohono O'odham, and Ute people, Ute portray the coyote as the companion of Creator deity, The Creator. A Tohono O'odham flood myth, flood story has Coyote helping Montezuma (mythology), Montezuma survive a global deluge that destroys humanity. After The Creator creates humanity, Coyote and Montezuma teach people how to live. The Crow Nation, Crow creation story portrays Old Man Coyote as The Creator. In Diné Bahaneʼ, The Dineh creation story, Coyote was present in the First World with First Man and First Woman, though a different version has it being created in the Fourth World. The Navajo Coyote brings death into the world, explaining that without death, too many people would exist, thus no room to plant corn.
Prior to the Spanish conquest of the Aztec Empire, Coyote played a significant role in Mesoamerican cosmology. The coyote symbolized military might in Mesoamerican chronology#Classic Era, Classic era Teotihuacan, with warriors dressing up in coyote costumes to call upon its predatory power. The species continued to be linked to Central Mexican warrior cults in the centuries leading up to the post-Classic Aztec rule.Schwartz, M. (1998). ''A History of Dogs in the Early Americas''. Yale University Press. pp. 146–149. .
In Aztec mythology, Huehuecoyotl, Huehuecóyotl (meaning "old coyote"), the god of dance, music and carnality, is depicted in several codices as a man with a coyote's head. He is sometimes depicted as a Promiscuity, womanizer, responsible for bringing war into the world by seducing Xochiquetzal, the goddess of love. Epigraphy, Epigrapher David H. Kelley argued that the god Quetzalcoatl owed its origins to pre-Aztec Uto-Aztecan languages, Uto-Aztecan mythological depictions of the coyote, which is portrayed as mankind's "Elder Brother", a creator, seducer, trickster, and culture hero linked to the morning star.
Coyote attacks on humans are uncommon and rarely cause serious injuries, due to the relatively small size of the coyote, but have been increasingly frequent, especially in California. There have been only two confirmed fatal attacks: one on a three-year-old named Kelly Keen coyote attack, Kelly Keen in Glendale, California and another on a nineteen-year-old named Taylor Mitchell in Nova Scotia, Canada. In the 30 years leading up to March 2006, at least 160 attacks occurred in the United States, mostly in the Los Angeles County area. Data from United States Department of Agriculture (USDA) Wildlife Services, the California Department of Fish and Game, and other sources show that while 41 attacks occurred during the period of 1988–1997, 48 attacks were verified from 1998 through 2003. The majority of these incidents occurred in Southern California near the suburban-wildland interface.
In the absence of the harassment of coyotes practiced by rural people, urban coyotes are losing their fear of humans, which is further worsened by people intentionally or unintentionally feeding coyotes. In such situations, some coyotes have begun to act aggressively toward humans, chasing joggers and bicyclists, confronting people walking their dogs, and stalking small children. Non-rabid coyotes in these areas sometimes target small children, mostly under the age of 10, though some adults have been bitten.
Although media reports of such attacks generally identify the animals in question as simply "coyotes", research into the genetics of the eastern coyote indicates those involved in attacks in northeast North America, including Pennsylvania, New York, New England, and eastern Canada, may have actually been Coywolf, coywolves, hybrids of ''Canis latrans'' and ''C. lupus,'' not fully coyotes.
, coyotes were the most abundant livestock predators in western North America, causing the majority of sheep, goat, and cattle losses. For example, according to the National Agricultural Statistics Service, coyotes were responsible for 60.5% of the 224,000 sheep deaths attributed to predation in 2004. The total number of sheep deaths in 2004 comprised 2.22% of the total sheep and lamb population in the United States, which, according to the National Agricultural Statistics Service USDA report, totaled 4.66 million and 7.80 million heads respectively as of July 1, 2005.
Because coyote populations are typically many times greater and more widely distributed than those of wolves, coyotes cause more overall predation losses. United States government agents routinely shoot, poison, trap, and kill about 90,000 coyotes each year to protect livestock. An Idaho census taken in 2005 showed that individual coyotes were 5% as likely to attack livestock as individual wolves. In Utah, more than 11,000 coyotes were killed for bounties totaling over $500,000 in the fiscal year ending June 30, 2017.
Livestock guardian dogs are commonly used to aggressively repel predators and have worked well in both fenced pasture and range operations. A 1986 survey of sheep producers in the USA found that 82% reported the use of dogs represented an economic asset.
Re-wilding cattle, which involves increasing the natural protective tendencies of cattle, is a method for controlling coyotes discussed by Temple Grandin of Colorado State University. This method is gaining popularity among producers who allow their herds to calve on the range and whose cattle graze open pastures throughout the year.
Coyotes typically Throat clamp, bite the throat just behind the jaw and below the ear when attacking adult sheep or goats, with death commonly resulting from suffocation. Blood loss is usually a secondary cause of death. Calves and heavily fleeced sheep are killed by attacking the flanks or hindquarters, causing shock and blood loss. When attacking smaller prey, such as young lambs, the kill is made by biting the skull and spinal regions, causing massive tissue and bone damage. Small or young prey may be completely carried off, leaving only blood as evidence of a kill. Coyotes usually leave the hide and most of the skeleton of larger animals relatively intact, unless food is scarce, in which case they may leave only the largest bones. Scattered bits of wool, skin, and other parts are characteristic where coyotes feed extensively on larger carcasses.
Tracks are an important factor in distinguishing coyote from dog predation. Coyote tracks tend to be more oval-shaped and compact than those of domestic dogs, and their claw marks are less prominent and the tracks tend to follow a straight line more closely than those of dogs. With the exception of sighthounds, most dogs of similar weight to coyotes have a slightly shorter stride. Coyote kills can be distinguished from wolf kills by less damage to the underlying tissues in the former. Also, coyote scat tends to be smaller than wolf scat.
Coyotes are often attracted to dog food and animals that are small enough to appear as prey. Items such as garbage, pet food, and sometimes feeding stations for birds and squirrels attract coyotes into backyards. About three to five pets attacked by coyotes are brought into the Animal Urgent Care hospital of South Orange County (California) each week, the majority of which are dogs, since cats typically do not survive the attacks. Scat analysis collected near Claremont, California, revealed that coyotes relied heavily on pets as a food source in winter and spring.
At one location in Southern California, coyotes began relying on a colony of feral cats as a food source. Over time, the coyotes killed most of the cats and then continued to eat the cat food placed daily at the colony site by people who were maintaining the cat colony.
Coyotes usually attack smaller-sized dogs, but they have been known to attack even large, powerful breeds such as the Rottweiler in exceptional cases. Dogs larger than coyotes, such as greyhounds, are generally able to drive them off and have been known to kill coyotes. Smaller breeds are more likely to suffer injury or death.
Coyote hunting is one of the most common forms of predator hunting that humans partake in. There are not many regulations with regard to the taking of the coyote which means there are many different methods that can be used to hunt the animal. The most common forms are trapping, Imitation, calling, and Dog, hound hunting. Since coyotes are colorblind, seeing only in shades of gray and subtle blues, open camouflages, and plain patterns can be used. As the average male coyote weighs 8 to 20 kg (18 to 44 lbs) and the average female coyote 7 to 18 kg (15 to 40 lbs), a universal projectile that can perform between those weights is the .223 Remington, so that the projectile expands in the target after entry, but before the exit, thus delivering the most energy.
Coyotes being the light and agile animals they are, they often leave a very light impression on terrain. The coyote's footprint is oblong, approximately 6.35 cm (2.5-inches) long and 5.08 cm (2-inches) wide. There are four claws in both their front and hind paws. The coyote's center pad is relatively shaped like that of a rounded triangle. Like the domestic dog the coyote's front paw is slightly larger than the hind paw. The coyote's paw is most similar to that of the domestic dog.
Prior to the mid-19th century, coyote fur was considered worthless. This changed with the diminution of North American beaver, beavers, and by 1860, the hunting of coyotes for their fur became a great source of income (75 Penny (United States coin), cents to United States dollar, $1.50 per skin) for wolfers (hunting), wolfers in the Great Plains. Coyote pelts were of significant economic importance during the early 1950s, ranging in price from $5 to $25 per pelt, depending on locality. The coyote's fur is not durable enough to make rugs, but can be used for coats and jackets, scarves, or muffs. The majority of pelts are used for making Trim (sewing), trimmings, such as coat collars and sleeves for women's clothing. Coyote fur is sometimes dyed black as imitation Silver fox (animal), silver fox.
Coyotes were occasionally eaten by trappers and mountain men during the Manifest destiny, western expansion. Coyotes sometimes featured in the feasts of the Plains Indians, and coyote pups were eaten by the indigenous people of San Gabriel, California. The taste of coyote meat has been likened to that of the wolf and is more tender than pork when boiled. Coyote fat, when taken in the fall, has been used on occasion to grease leather or eaten as a Spread (food), spread.

The coyote has 19 recognized subspecies. The average male weighs and the average female . Their fur color is predominantly light gray and red or fulvous interspersed with black and white, though it varies somewhat with geography. It is highly flexible in social organization, living either in a family unit or in loosely knit packs of unrelated individuals. Primarily carnivorous, its diet consists mainly of deer, rabbits, hares, rodents, birds, reptiles, amphibians, fish, and invertebrates, though it may also eat fruits and vegetables on occasion. Its characteristic vocalization is a howling, howl made by solitary individuals. Humans are the coyote's greatest threat, followed by North American cougar, cougars and gray wolves. In spite of this, coyotes sometimes mate with gray, eastern, or red wolves, producing "coywolf" hybrids. In the northeastern regions of North America, the eastern coyote (a larger subspecies, though still smaller than wolves) is the result of various historical and recent matings with various types of wolves. Genetic studies show that most North American wolves contain some level of coyote DNA.
The coyote is a prominent character in Indigenous peoples of the Americas, Native American folklore, mainly in Aridoamerica, usually depicted as a trickster that alternately assumes the form of an actual coyote or a man. As with other trickster figures, the coyote uses deception and humor to rebel against social conventions. The animal was especially respected in Mesoamerican cosmology as a symbol of military might. After the European colonization of the Americas, it was seen in Anglo-American culture as a cowardly and untrustworthy animal. Unlike wolves, which have seen their public image improve, attitudes towards the coyote remain largely negative.
Description
Coyote males average in weight, while females average , though size varies geographically. Northern subspecies, which average , tend to grow larger than the southern subspecies of Mexico, which average . Total length ranges on average from ; comprising a tail length of , with females being shorter in both body length and height. The largest coyote on record was a male killed near Afton, Wyoming, on November19, 1937, which measured from nose to tail, and weighed . Scent glands are located at the upper side of the base of the tail and are a bluish-black color.
The color and texture of the coyote's fur vary somewhat geographically. The hair's predominant color is light gray and red or fulvous, interspersed around the body with black and white. Coyotes living at high elevations tend to have more black and gray shades than their desert-dwelling counterparts, which are more fulvous or whitish-gray. The coyote's fur consists of short, soft underfur and long, coarse guard hairs. The fur of northern subspecies is longer and denser than in southern forms, with the fur of some Mexican and Central American forms being almost hispid (bristly). Generally, adult coyotes (including coywolf hybrids) have a sable coat color, dark neonatal coat color, bushy tail with an active supracaudal gland, and a white facial mask. Albinism is extremely rare in coyotes. Out of a total of 750,000 coyotes killed by federal and cooperative hunters between March 1938, and June 1945, only two were albinos.
The coyote is typically smaller than the gray wolf, but has longer ears and a relatively larger Neurocranium, braincase, as well as a thinner frame, face, and muzzle. The scent glands are smaller than the gray wolf's, but are the same color. Its fur color variation is much less varied than that of a wolf. The coyote also carries its tail downwards when running or walking, rather than horizontally as the wolf does.
Coyote tracks can be distinguished from those of dogs by their more elongated, less rounded shape. Unlike dogs, the upper canines of coyotes extend past the mental foramina.
Taxonomy and evolution
History
At the time of the European colonization of the Americas, coyotes were largely confined to open plains and arid regions of the western half of the continent. In early post-Columbian historical records, determining whether the writer is describing coyotes or wolves is often difficult. One record from 1750 in Kaskaskia, Illinois, written by a local priest, noted that the "wolves" encountered there were smaller and less daring than European wolves. Another account from the early 1800's in Edwards County, Illinois, Edwards County mentioned wolves howling at night, though these were likely coyotes. This species was encountered several times during the Lewis and Clark Expedition (1804–1806), though it was already well known to European traders on the upper Missouri River, Missouri. Meriwether Lewis, writing on 5 May 1805, in northeastern Montana, described the coyote in these terms:
The coyote was first scientifically described by naturalist Thomas Say in September 1819, on the site of Lewis and Clark's Council Bluffs, up the Missouri River from the mouth of the Platte during a Stephen Harriman Long#1817-23 expeditions up the Missouri and Platte Rivers, government-sponsored expedition with Major Stephen Harriman Long, Stephen Long. He had the first edition of the Lewis and Clark journals in hand, which contained Biddle's edited version of Lewis's observations dated 5 May 1805. His account was published in 1823. Thomas Say, Say was the first person to document the difference between a "''prairie wolf''" (coyote) and on the next page of his journal a wolf which he named ''Canis nubilus'' (Great Plains wolf). Say described the coyote as:
Naming and etymology
The earliest written reference to the species comes from the naturalist Francisco Hernández de Toledo, Francisco Hernández's ''Plantas y Animales de la Nueva España'' (1651), where it is described as a "Spanish fox" or "jackal". The first published usage of the word "coyote" (which is a Spanish borrowing of its Nahuatl name ''coyōtl'' ) comes from the historian Francisco Javier Clavijero's ''Historia de México'' in 1780. The first time it was used in English language, English occurred in William Bullock (collector), William Bullock's ''Six months' residence and travels in Mexico'' (1824), where it is variously transcribed as ''cayjotte'' and ''cocyotie''. The word's spelling was standardized as "coyote" by the 1880s. Alternative English names for the coyote include "prairie wolf", "brush wolf", "cased wolf", "little wolf" and "American jackal". Its binomial name ''Canis latrans'' translates to "barking dog", a reference to the many vocalizations they produce.Evolution
Fossil record
Xiaoming Wang (paleontologist), Xiaoming Wang and Richard H. Tedford, one of the foremost Author citation (zoology), authorities on carnivore evolution, proposed that the genus ''Canis'' was the descendant of the coyote-like ''Eucyon davisi'' and its remains first appeared in the Miocene 6million years ago (Mya) in the southwestern US and Mexico. By the Pliocene (5Mya), the larger ''Canis lepophagus'' appeared in the same region and by the early Pleistocene (1Mya) ''C.latrans'' (the coyote) was in existence. They proposed that the progression from ''Eucyon davisi'' to ''C.lepophagus'' to the coyote was linear evolution. ''C.latrans'' and ''C. aureus'' are closely related to ''Canis edwardii, C.edwardii'', a species that appeared earliest spanning the mid-Blancan (late Pliocene) to the close of the Irvingtonian (late Pleistocene), and coyote remains indistinguishable from ''C. latrans'' were contemporaneous with ''C.edwardii'' in North America. Johnston describes ''C.lepophagus'' as having a more slender skull and skeleton than the modern coyote. Ronald Nowak found that the early populations had small, delicate, narrowly proportioned skulls that resemble small coyotes and appear to be ancestral to ''C. latrans''. ''C. lepophagus'' was similar in weight to modern coyotes, but had shorter limb bones that indicate a less cursorial lifestyle. The coyote represents a more primitive form of ''Canis'' than the gray wolf, as shown by its relatively small size and its comparatively narrow skull and jaws, which lack the grasping power necessary to hold the large prey in which wolves specialize. This is further corroborated by the coyote's sagittal crest, which is low or totally flattened, thus indicating a weaker bite than the wolves. The coyote is not a specialized carnivore as the wolf is, as shown by the larger chewing surfaces on the molar (tooth), molars, reflecting the species' relative dependence on vegetable matter. In these respects, the coyote resembles the fox-like progenitors of the genus more so than the wolf. The oldest fossils that fall within the range of the modern coyote date to 0.74–0.85 Megaannum, Ma (million years) in Hamilton Cave, West Virginia; 0.73 Ma in Irvington, California; 0.35–0.48 Ma in Porcupine Cave, Colorado, and in Cumberland Cave, Pennsylvania. Modern coyotes arose 1,000 years after the Quaternary extinction event. Compared to their modern Holocene counterparts, Pleistocene coyotes (''C.l. orcutti'') were larger and more robust, likely in response to larger Competition (biology), competitors and prey. Pleistocene coyotes were likely more specialized carnivores than their descendants, as their teeth were more adapted to shearing meat, showing fewer grinding surfaces suited for processing vegetation. Their reduction in size occurred within 1,000 years of the Quaternary extinction event, when their large prey died out. Furthermore, Pleistocene coyotes were unable to exploit the big-game hunting Ecological niche, niche left vacant after the extinction of the dire wolf (''Aenocyondirus''), as it was rapidly filled by gray wolves, which likely actively killed off the large coyotes, with natural selection favoring the modern gracile morph.DNA evidence
In 1993, a study proposed that the wolves of North America display skull traits more similar to the coyote than wolves from Eurasia. In 2010, a study found that the coyote was a lineage (genetic)#Basal lineage, basal member of the clade that included the Tibetan wolf, the Dog, domestic dog, the Mongolian wolf and the Eurasian wolf, with the Tibetan wolf diverging early from wolves and domestic dogs.
In 2016, a Whole genome sequencing, whole-genome DNA study proposed, based on the assumptions made, that all of the North American wolves and coyotes diverged from a common ancestor about 51,000 years ago. However, the proposed timing of the wolf / coyote divergence conflicts with the discovery of a coyote-like specimen in strata dated to 1 Mya. The study also indicated that all North American wolves have a significant amount of coyote ancestry and all coyotes some degree of wolf ancestry, and that the red wolf and eastern wolf are highly Genetic admixture, admixed with different proportions of gray wolf and coyote ancestry.
Genetic studies relating to wolves or dogs have inferred phylogenetic relationships based on the only reference genome available, that of the Boxer dog. In 2017, the first reference genome of the wolf ''Canis lupus lupus'' was mapped to aid future research. In 2018, a study looked at the genomic structure and admixture of North American wolves, wolf-like canids, and coyotes using specimens from across their entire range that mapped the largest dataset of nuclear genome sequences against the wolf reference genome.
The study supports the findings of previous studies that North American gray wolves and wolf-like canids were the result of complex gray wolf and coyote mixing. A polar wolf from Greenland and a coyote from Mexico represented the purest specimens. The coyotes from Alaska, California, Alabama, and Quebec show almost no wolf ancestry. Coyotes from Missouri, Illinois, and Florida exhibit 5–10% wolf ancestry. There was 40% wolf to 60% coyote ancestry in red wolves, 60% wolf to 40% coyote in Eastern timber wolves, and 75% wolf to 25% coyote in the Great Lakes wolves. There was 10% coyote ancestry in Mexican wolves and the Atlantic Coast wolves, 5% in Pacific Coast and Yellowstone wolves, and less than 3% in Canadian archipelago wolves. If a third canid had been involved in the admixture of the North American wolf-like canids, then its genetic signature would have been found in coyotes and wolves, which it has not.
In 2018, whole genome sequencing was used to compare members of the genus ''Canis''. The study indicates that the common ancestor of the coyote and gray wolf
The wolf (''Canis lupus''; : wolves), also known as the gray wolf or grey wolf, is a large canine native to Eurasia and North America. More than thirty subspecies of ''Canis lupus'' have been recognized, and gray wolves, as popularly u ...
has genetically Genetic admixture, admixed with a ghost population of an extinct, unidentified canid. The "ghost" canid was genetically close to the dhole, and had evolved after the divergence of the African wild dog from the other canid species. The Basal (phylogenetics), basal position of the coyote compared to the wolf is proposed to be due to the coyote retaining more of the mitochondrial genome from the unknown extinct canid.
Subspecies
, 19 subspecies are recognized. Geographic variation in coyotes is not great, though taken as a whole, the eastern subspecies ( and ) are large, dark-colored animals, with a gradual paling in color and reduction in size westward and northward (, , , and ), a brightening of Ochre, 'ochraceous' tones – deep orange or brown – towards the Pacific coast (, ), a reduction in size in Aridoamerica (, ) and a general trend towards dark reddish colors and short muzzles in Mexican and Central American populations.Hybridization
Coyotes occasionally mate with Dog, domestic dogs, sometimes producing crosses colloquially known as "coydogs". Such matings are rare in the wild, as the mating cycles of dogs and coyotes do not coincide, and coyotes are usually antagonistic towards dogs. Hybridization usually only occurs when coyotes are expanding into areas where conspecifics are few, and dogs are the only alternatives. Even then, pup survival rates are lower than normal, as dogs do not form pair bonds with coyotes, thus making the rearing of pups more difficult. In captivity, F1 hybrid, F1 hybrids (first generation) tend to be more mischievous and less manageable as pups than dogs, and are less trustworthy on maturity than Wolfdog, wolf-dog hybrids.
Hybrids vary in appearance, but generally retain the coyote's #Description, usual characteristics. F1 hybrids tend to be intermediate in form between dogs and coyotes, while F2 hybrids (second generation) are more varied. Both F1 and F2 hybrids resemble their coyote parents in terms of shyness and intrasexual aggression. Hybrids are fertile and can be successfully bred through four generations. Melanism, Melanistic coyotes owe their black pelts to a mutation that first arose in domestic dogs. A population of nonalbino white coyotes in Newfoundland owe their coloration to a melanocortin 1 receptor mutation inherited from Golden Retrievers.
Coyotes have hybridized with wolves to varying degrees, particularly in eastern North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Car ...
. The so-called "eastern coyote" of northeastern North America probably originated in the aftermath of the extermination of gray and eastern wolves in the northeast, thus allowing coyotes to colonize former wolf ranges and mix with the remnant wolf populations. This hybrid is smaller than either the gray or eastern wolf, and holds smaller territories, but is in turn larger and holds more extensive home ranges than the typical western coyote. , the eastern coyote's genetic makeup is fairly uniform, with minimal influence from eastern wolves or western coyotes.
Adult eastern coyotes are larger than western coyotes, with female eastern coyotes weighing 21% more than male western coyotes. Physical differences become more apparent by the age of 35 days, with eastern coyote pups having longer legs than their western counterparts. Differences in dental development also occurs, with tooth eruption being later, and in a different order in the eastern coyote. Aside from its size, the eastern coyote is physically similar to the western coyote. The four color phases range from dark brown to blond or reddish blond, though the most common phase is gray-brown, with reddish legs, ears, and flanks.
No significant differences exist between eastern and western coyotes in aggression and fighting, though eastern coyotes tend to fight less, and are more playful. Unlike western coyote pups, in which fighting precedes play behavior, fighting among eastern coyote pups occurs after the onset of play. Eastern coyotes tend to reach sexual maturity at two years of age, much later than in western coyotes.
Eastern and red wolves are also products of varying degrees of wolf-coyote hybridization. The eastern wolf probably was a result of a wolf-coyote admixture, combined with extensive backcrossing with parent gray wolf populations. The red wolf may have originated during a time of declining wolf populations in the Southeastern Woodlands, forcing a wolf-coyote hybridization, as well as backcrossing with local parent coyote populations to the extent that about 75–80% of the modern red wolf's genome is of coyote derivation.
Behavior
Social and reproductive behaviors
Like the Eurasian golden jackal, the coyote is gregarious, but not as dependent on Biological specificity, conspecifics as more social canid species like wolves are. This is likely because the coyote is not a specialized hunter of large prey as the latter species is. The basic social unit of a coyote pack is a family containing a reproductive female. However, unrelated coyotes may join forces for companionship, or to bring down prey too large to attack singly. Such "nonfamily" packs are only temporary, and may consist of bachelor males, nonreproductive females and subadult young. Families are formed in midwinter, when females enter estrus. Pair bonding can occur 2–3 months before actual Copulation (zoology), copulation takes place.
The copulatory tie can last 5–45 minutes. A female entering estrus attracts males by scent marking and howling with increasing frequency. A single female in heat can attract up to seven reproductive males, which can follow her for as long as a month. Although some squabbling may occur among the males, once the female has selected a mate and copulates, the rejected males do not intervene, and move on once they detect other estrous females. Unlike the wolf, which has been known to practice both Monogamy in animals, monogamous and bigamous matings, the coyote is strictly monogamous, even in areas with high coyote densities and abundant food.
Females that fail to mate sometimes assist their sisters or mothers in raising their pups, or join their siblings until the next time they can mate. The newly mated pair then establishes a territory and either constructs their own den or cleans out abandoned American badger, badger, marmot, or skunk earths. During the pregnancy, the male frequently hunts alone and brings back food for the female. The female may line the den with dried grass or with fur pulled from her belly. The gestation period is 63 days, with an average litter size of six, though the number fluctuates depending on coyote population density and the abundance of food.
Coyote pups are born in dens, hollow trees, or under ledges, and weigh at birth. They are altricial, and are completely dependent on milk for their first 10 days. The incisors erupt at about 12 days, the canine teeth, canines at 16, and the second premolars at 21. Their eyes open after 10 days, by which point the pups become increasingly more mobile, walking by 20 days, and running at the age of six weeks. The parents begin supplementing the pup's diet with regurgitated solid food after 12–15 days. By the age of four to six weeks, when their milk teeth are fully functional, the pups are given small food items such as mice, rabbits, or pieces of ungulate carcasses, with lactation steadily decreasing after two months.
Unlike wolf pups, coyote pups begin seriously fighting (as opposed to play fighting) prior to engaging in play behavior. A common play behavior includes the coyote "hip-slam". By three weeks of age, coyote pups bite each other with less inhibition than wolf pups. By the age of four to five weeks, pups have established dominance hierarchies, and are by then more likely to play rather than fight. The male plays an active role in feeding, grooming, and guarding the pups, but abandons them if the female goes missing before the pups are completely Weaning, weaned. The den is abandoned by June to July, and the pups follow their parents in patrolling their territory and hunting. Pups may leave their families in August, though can remain for much longer. The pups attain adult dimensions at eight months and gain adult weight a month later.
Territorial and sheltering behaviors
Individual feeding territories vary in size from , with the general concentration of coyotes in a given area depending on food abundance, adequate denning sites, and competition with conspecifics and other predators. The coyote generally does not defend its territory outside of the denning season, and is much less aggressive towards intruders than the wolf is, typically chasing and sparring with them, but rarely killing them. Conflicts between coyotes can arise during times of food shortage. Coyotes mark their territories by raised-leg urination and ground-scratching. Like wolves, coyotes use a den, usually the deserted holes of other species, when gestating and rearing young, though they may occasionally give birth under sagebrushes in the open. Coyote dens can be located in canyons, Washout (erosion), washouts, coulees, Bank (geography), banks, rock bluffs, or level ground. Some dens have been found under abandoned homestead shacks, grain bins, drainage pipes, railroad tracks, hollow logs, thickets, and thistles. The den is continuously dug and cleaned out by the female until the pups are born. Should the den be disturbed or infested with fleas, the pups are moved into another den. A coyote den can have several entrances and passages branching out from the main chamber. A single den can be used year after year.Hunting and feeding behaviors
While the popular consensus is that olfaction is very important for hunting, two studies that experimentally investigated the role of olfactory, auditory, and visual cues found that visual cues are the most important ones for hunting in red foxes and coyotes.
When hunting large prey, the coyote often works in pairs or small groups. Success in killing large ungulates depends on factors such as snow depth and crust density. Younger animals usually avoid participating in such hunts, with the breeding pair typically doing most of the work. The coyote pursues large prey, typically hamstringing the animal, and subsequently then harassing it until the prey falls. Like other canids, the coyote Hoarding (animal behavior), caches excess food. Coyotes catch mouse-sized rodents by pouncing, whereas ground squirrels are chased. Although coyotes can live in large groups, small prey is typically caught singly.
Coyotes have been observed to kill North American porcupine, porcupines in pairs, using their paws to flip the rodents on their backs, then attacking the soft underbelly. Only old and experienced coyotes can successfully prey on porcupines, with many predation attempts by young coyotes resulting in them being injured by their prey's quills. Coyotes sometimes urination, urinate on their food, possibly to claim ownership over it.Wells, Michael C., and Marc Bekoff.An observational study of scent-marking in coyotes, Canis latrans
" (1981). Recent evidence demonstrates that at least some coyotes have become more nocturnal in hunting, presumably to avoid humans. Coyotes may occasionally form mutualism (biology), mutualistic hunting relationships with American badgers, assisting each other in digging up rodent prey. The relationship between the two species may occasionally border on apparent "friendship", as some coyotes have been observed laying their heads on their badger companions or licking their faces without protest. The amicable interactions between coyotes and badgers were known to pre-Columbian civilizations, as shown on a jar found in Mexico dated to 1250–1300 Current era, CE depicting the relationship between the two. Food scraps, pet food, and animal feces may attract a coyote to a trash can.
Communication
Body language
Being both a gregarious and solitary animal, the variability of the coyote's visual and vocal repertoire is intermediate between that of the solitary foxes and the highly social wolf. The aggressive behavior of the coyote bears more similarities to that of foxes than it does that of wolves and dogs. An aggressive coyote arches its back and lowers its tail. Unlike dogs, which solicit playful behavior by performing a "play-bow" followed by a "play-leap", play in coyotes consists of a bow, followed by side-to-side head flexions and a series of "spins" and "dives". Although coyotes will sometimes bite their playmates' scruff as dogs do, they typically approach low, and make upward-directed bites. Pups fight each other regardless of sex, while among adults, aggression is typically reserved for members of the same sex. Combatants approach each other waving their tails and snarling with their jaws open, though fights are typically silent. Males tend to fight in a vertical stance, while females fight on all four paws. Fights among females tend to be more serious than ones among males, as females seize their opponents' forelegs, throat, and shoulders.Vocalizations
The coyote has been described as "the most vocal of all [wild] North American mammals". Its loudness and range of vocalizations was the cause for its binomial name ''Canis latrans'', meaning "barking dog". At least 11 different vocalizations are known in adult coyotes. These sounds are divided into three categories: agonistic and alarm, greeting, and contact. Vocalizations of the first category include woofs, growls, huffs, barks, bark howls, yelps, and high-frequency whines. Woofs are used as low-intensity threats or alarms and are usually heard near den sites, prompting the pups to immediately retreat into their burrows. Growls are used as threats at short distances but have also been heard among pups playing and copulating males. Huffs are high-intensity threat vocalizations produced by rapid expiration of air. Barks can be classed as both long-distance threat vocalizations and alarm calls. Bark howls may serve similar functions. Yelps are emitted as a sign of submission, while high-frequency whines are produced by dominant animals acknowledging the submission of subordinates. Greeting vocalizations include low-frequency whines, 'wow-oo-wows', and group yip howls. Low-frequency whines are emitted by submissive animals and are usually accompanied by tail wagging and muzzle nibbling. The sound known as 'wow-oo-wow' has been described as a "greeting song". The group yip howl is emitted when two or more pack members reunite and may be the final act of a complex greeting ceremony. Contact calls include lone howls and group howls, as well as the previously mentioned group yip howls. The lone howl is the most iconic sound of the coyote and may serve the purpose of announcing the presence of a lone individual separated from its pack. Group howls are used as both substitute group yip howls and as responses to either lone howls, group howls, or group yip howls.Ecology
Habitat
Prior to the near extermination of wolves and cougars, the coyote was most numerous in grasslands inhabited by American bison, bison, pronghorn, elk, and other deer, doing particularly well in short-grass areas with prairie dogs, though it was just as much at home in semiarid areas with sagebrush and jackrabbits or in deserts inhabited by cactus, kangaroo rats, and rattlesnakes. As long as it was not in direct competition with the wolf, the coyote ranged from the Sonoran Desert to the alpine regions of adjoining mountains or the plains and mountainous areas of Alberta. With the extermination of the wolf, the coyote's range expanded to encompass broken forests from the tropics of Guatemala and the northern slope of Alaska.
Coyotes walk around per day, often along trails such as logging roads and paths; they may use iced-over rivers as travel routes in winter. They are often crepuscular, being more active around evening and the beginning of the night than during the day. However, in urban areas coyotes are known to be more nocturnal, likely to avoid encounters with humans. Like many canids, coyotes are competent swimmers, reported to be able to travel at least across water.
Diet
The coyote is ecologically the North American equivalent of the Eurasian golden jackal
The golden jackal (''Canis aureus''), also called common jackal, is a wolf-like canid that is native to Southeast Europe, Southwest Asia, South Asia, and regions of Southeast Asia. The golden jackal's coat varies in color from a pale creamy y ...
. Likewise, the coyote is highly versatile in its choice of food, but is primarily carnivorous, with 90% of its diet consisting of meat. Prey species include American bison, bison (largely as carrion), white-tailed deer, mule deer, moose, elk, bighorn sheep, pronghorn, rabbits, hares, rodents, birds (especially galliformes, roadrunners, young water birds and Columbidae, pigeons and doves), amphibians (except toads), lizards, snakes, turtles and tortoises, fish, crustaceans, and insects. Coyotes may be picky over the prey they target, as animals such as shrews, Mole (animal), moles, and brown rats do not occur in their diet in proportion to their numbers.
Terrestrial animals, terrestrial and/or burrowing small mammals such as ground squirrels and associated species (marmots, prairie dogs, chipmunks) as well as voles, pocket gophers, kangaroo rats and other ground-favoring rodents may be quite common foods, especially for lone coyotes. More unusual prey include Fisher (animal), fishers, young American black bear, black bear cubs, harp seals and rattlesnakes. Coyotes kill rattlesnakes mostly for food, but also to protect their pups at their dens, by teasing the snakes until they stretch out and then biting their heads and snapping and shaking the snakes. Birds taken by coyotes may range in size from thrashers, larks and Passerellidae, sparrows to adult wild turkeys and, rarely, brooding adult Trumpeter swan, swans and American white pelican, pelicans.
If working in packs or pairs, coyotes may have access to larger prey than lone individuals normally take, such as various prey weighing more than .Gese, E. M., Rongstad, O. J., & Mytton, W. R. (1988). ''Relationship between coyote group size and diet in southeastern Colorado''. The Journal of Wildlife Management, 647–653. In some cases, packs of coyotes have dispatched much larger prey such as adult ''Odocoileus'' deer, cow elk, pronghorns and Ovis, wild sheep, although the young fawn, calves and lambs of these animals are considerably more often taken even by packs, as well as domestic sheep and Cattle, domestic cattle. In some cases, coyotes can bring down prey weighing up to or more. When it comes to adult ungulates such as wild deer, they often exploit them when vulnerable such as those that are infirm, stuck in snow or ice, otherwise winter-weakened or heavily pregnant, whereas less wary domestic ungulates may be more easily exploited.
Although coyotes prefer fresh meat, they will scavenge when the opportunity presents itself. Excluding the insects, fruit, and grass eaten, the coyote requires an estimated of food daily, or annually. The coyote readily cannibalism (zoology), cannibalizes the carcasses of conspecifics, with coyote fat having been successfully used by coyote hunters as a lure or poisoned bait. The coyote's winter diet consists mainly of large ungulate carcasses, with very little plant matter. Rodent prey increases in importance during the spring, summer, and fall.
The coyote feeds on a variety of different produce, including blackberry, blackberries, blueberry, blueberries, peaches, pears, apples, Opuntia, prickly pears, chapotes, persimmons, peanuts, watermelons, cantaloupes, and carrots. During the winter and early spring, the coyote eats large quantities of grass, such as green wheat blades. It sometimes eats unusual items such as Cottonseed meal, cotton cake, soybean meal, domestic animal droppings, beans, and cultivated grain such as maize, wheat, and sorghum.
In coastal California, coyotes now consume a higher percentage of marine-based food than their ancestors, which is thought to be due to the extirpation of the grizzly bear from this region. In Death Valley, coyotes may consume great quantities of hawkmoth caterpillars or beetles in the spring flowering months.
Enemies and competitors
In areas where the ranges of coyotes and gray wolves overlap, interference competition and predation by wolves has been hypothesized to limit local coyote densities. Coyote ranges expanded during the 19th and 20th centuries following the extirpation of wolves, while coyotes were driven to extinction on Isle Royale after wolves colonized the island in the 1940s. One study conducted in Yellowstone National Park, where both species coexist, concluded that the coyote population in the Lamar River, Lamar River Valley declined by 39% following the reintroduction of wolves in the 1990s, while coyote populations in wolf inhabited areas of the Grand Teton National Park are 33% lower than in areas where they are absent. Wolves have been observed to not tolerate coyotes in their vicinity, though coyotes have been known to trail wolves to feed on their kills.
Coyotes may compete with cougars in some areas. In the eastern Sierra Nevada, coyotes compete with cougars over mule deer. Cougars normally outcompete and dominate coyotes, and may kill them occasionally, thus reducing coyote predation pressure on smaller carnivores such as foxes and bobcats. Coyotes that are killed are sometimes not eaten, perhaps indicating that these comprise competitive interspecies interactions, however there are multiple confirmed cases of cougars also eating coyotes. In northeastern Mexico, cougar predation on coyotes continues apace but coyotes were absent from the prey spectrum of sympatric jaguars, apparently due to differing habitat usages.
Other than by gray wolves and cougars, predation on adult coyotes is relatively rare but multiple other predators can be occasional threats. In some cases, adult coyotes have been preyed upon by both American black bear, American black and grizzly bears, American alligators, large Canada lynx and golden eagles. At kill sites and carrion, coyotes, especially if working alone, tend to be dominated by wolves, cougars, bears, wolverines and, usually but not always, eagles (i.e., Bald eagle, bald and golden). When such larger, more powerful and/or more aggressive predators such as these come to a shared feeding site, a coyote may either try to fight, wait until the other predator is done or occasionally share a kill, but if a major danger such as wolves or an adult cougar is present, the coyote will tend to flee.
Coyotes rarely kill healthy adult red foxes, and have been observed to feed or den alongside them, though they often kill foxes caught in traps. Coyotes may kill fox kits, but this is not a major source of mortality. In southern California, coyotes frequently kill gray foxes, and these smaller canids tend to avoid areas with high coyote densities.
In some areas, coyotes share their ranges with bobcats. These two similarly-sized species rarely physically confront one another, though bobcat populations tend to diminish in areas with high coyote densities. However, several studies have demonstrated interference competition between coyotes and bobcats, and in all cases coyotes dominated the interaction. Multiple researchers reported instances of coyotes killing bobcats, whereas bobcats killing coyotes is more rare. Coyotes attack bobcats using a bite-and-shake method similar to what is used on medium-sized prey. Coyotes, both single individuals and groups, have been known to occasionally kill bobcats. In most cases, the bobcats were relatively small specimens, such as adult females and juveniles.
Coyote attacks, by an unknown number of coyotes, on adult male bobcats have occurred. In California, coyote and bobcat populations are not negatively correlated across different habitat types, but predation by coyotes is an important source of mortality in bobcats. Biologist Stanley Paul Young noted that in his entire trapping career, he had never successfully saved a captured bobcat from being killed by coyotes, and wrote of two incidents wherein coyotes chased bobcats up trees. Coyotes have been documented to directly kill Canada lynx on occasion, and compete with them for prey, especially snowshoe hares. In some areas, including central Alberta, lynx are more abundant where coyotes are few, thus interactions with coyotes appears to influence lynx populations more than the availability of snowshoe hares.
Range
Due to the coyote's wide range and abundance throughout North America, it is listed as Least Concern by the International Union for Conservation of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natu ...
(IUCN). The coyote's pre-Columbian range was limited to the Southwest and Plains regions of North America, and northern and central Mexico. By the 19th century, the species expanded north and east, expanding further after 1900, coinciding with land conversion and the extirpation of wolves. By this time, its range encompassed the entire North American continent, including all of the contiguous United States and Mexico, southward into Central America, and northward into most of Canada and Alaska. This expansion is ongoing, and the species now occupies the majority of areas between 8°N (Panama) and 70°N (northern Alaska).
Although it was once widely believed that coyotes are recent immigrants to southern Mexico and Central America, aided in their expansion by deforestation, Pleistocene and Early Holocene records, as well as records from the pre-Columbian period and early European colonization show that the animal was present in the area long before modern times. Range expansion occurred south of Costa Rica during the late 1970s and northern Panama in the early 1980s, following the expansion of cattle-grazing lands into tropical rain forests.
The coyote is predicted to appear in northern Belize in the near future, as the habitat there is favorable to the species. Concerns have been raised of a possible expansion into South America through the Isthmus of Panama, Panamanian Isthmus, should the Darién Gap ever be closed by the Pan-American Highway. This fear was partially confirmed in January 2013, when the species was recorded in eastern Panama's Chepo District, beyond the Panama Canal
The Panama Canal ( es, Canal de Panamá, link=no) is an artificial waterway in Panama that connects the Atlantic Ocean with the Pacific Ocean and divides North and South America. The canal cuts across the Isthmus of Panama and is a conduit ...
.
A 2017 genetic study proposes that coyotes were originally not found in the area of the eastern United States. From the 1890s, dense forests were transformed into agricultural land and wolf control implemented on a large scale, leaving a niche for coyotes to disperse into. There were two major dispersals from two populations of genetically distinct coyotes. The first major dispersal to the northeast came in the early 20th century from those coyotes living in the northern Great Plains. These came to New England via the northern Great Lakes region and southern Canada, and to Pennsylvania via the southern Great Lakes region, meeting together in the 1940s in New York and Pennsylvania.
These coyotes have hybridized with the remnant gray wolf and eastern wolf populations, which has added to coyote genetic diversity and may have assisted adaptation to the new niche. The second major dispersal to the southeast came in the mid-20th century from Texas and reached the Carolinas in the 1980s. These coyotes have hybridized with the remnant red wolf populations before the 1970s when the red wolf was extirpated in the wild, which has also added to coyote genetic diversity and may have assisted adaptation to this new niche as well. Both of these two major coyote dispersals have experienced rapid population growth and are forecast to meet along the mid-Atlantic coast. The study concludes that for coyotes the long range dispersal, gene flow from local populations, and rapid population growth may be inter-related.
Diseases and parasites
Among large North American carnivores, the coyote probably carries the largest number of diseases and parasites, likely due to its wide range and varied diet. Viral diseases known to infect coyotes include rabies, canine distemper, infectious canine hepatitis, four strains of equine encephalitis, and Oral florid papillomatosis, oral papillomatosis. By the late 1970s, serious rabies outbreaks in coyotes had ceased to be a problem for over 60 years, though sporadic cases every 1–5 years did occur. Distemper causes the deaths of many pups in the wild, though some specimens can survive infection. ''Tularemia'', a bacterial disease, infects coyotes from tick bites and through their rodent and lagomorph prey, and can be deadly for pups.
Coyotes can be infected by both Demodicosis, demodectic and sarcoptic mange, the latter being the most common. Mite infestations are rare and incidental in coyotes, while tick infestations are more common, with seasonal peaks depending on locality (May–August in the Northwest, March–November in Arkansas). Coyotes are only rarely infested with Louse, lice, while fleas infest coyotes from puphood, though they may be more a source of irritation than serious illness. ''Pulex, Pulex simulans'' is the most common species to infest coyotes, while ''Ctenocephalides canis'' tends to occur only in places where coyotes and dogs (its primary host) inhabit the same area. Although coyotes are rarely host to Trematoda, flukes, they can nevertheless have serious effects on coyotes, particularly ''Nanophyetus salmincola'', which can infect them with salmon poisoning disease, a disease with a 90% mortality rate. Trematode ''Metorchis conjunctus'' can also infect coyotes.
Tapeworms have been recorded to infest 60–95% of all coyotes examined. The most common species to infest coyotes are ''Taenia pisiformis'' and ''Taenia crassiceps'', which uses cottontail rabbits as intermediate hosts. The largest species known in coyotes is ''T. hydatigena'', which enters coyotes through infected ungulates, and can grow to lengths of . Although once largely limited to wolves, ''Echinococcus granulosus'' has expanded to coyotes since the latter began colonizing former wolf ranges.
The most frequent Ascarididae, ascaroid roundworm in coyotes is ''Toxascaris leonina'', which dwells in the coyote's small intestine and has no ill effects, except for causing the host to eat more frequently. Hookworms of the genus ''Ancylostoma'' infest coyotes throughout their range, being particularly prevalent in humid areas. In areas of high moisture, such as coastal Texas, coyotes can carry up to 250 hookworms each. The blood-drinking ''Ancylostoma caninum, A. caninum'' is particularly dangerous, as it damages the coyote through blood loss and lung congestion. A 10-day-old pup can die from being host to as few as 25 ''A. caninum'' worms.
Relationships with humans
In folklore and mythology
Coyote features as a trickster figure and skin-walker in the folktales of some Native Americans in the United States, Native Americans, notably several nations in the Indigenous peoples of the North American Southwest, Southwestern and Plains Indians, Plains regions, where he alternately assumes the form of an actual coyote or that of a man. As with other trickster figures, Coyote acts as a picaresque hero who rebels against social convention through deception and humor. Folklorists such as Harris believe coyotes came to be seen as tricksters due to the animal's intelligence and adaptability. After the European colonization of the Americas, Anglo-American depictions of Coyote are of a cowardly and untrustworthy animal. Unlike the gray wolf, which has undergone a radical improvement of its public image, Anglo-American cultural attitudes towards the coyote remain largely negative.
In the Maidu creation story, Coyote introduces work, suffering, and death to the world. Zuni people, Zuni lore has Coyote bringing winter into the world by stealing light from the kachinas. The Chinookan peoples, Chinook, Maidu, Pawnee people, Pawnee, Tohono O'odham, and Ute people, Ute portray the coyote as the companion of Creator deity, The Creator. A Tohono O'odham flood myth, flood story has Coyote helping Montezuma (mythology), Montezuma survive a global deluge that destroys humanity. After The Creator creates humanity, Coyote and Montezuma teach people how to live. The Crow Nation, Crow creation story portrays Old Man Coyote as The Creator. In Diné Bahaneʼ, The Dineh creation story, Coyote was present in the First World with First Man and First Woman, though a different version has it being created in the Fourth World. The Navajo Coyote brings death into the world, explaining that without death, too many people would exist, thus no room to plant corn.
Prior to the Spanish conquest of the Aztec Empire, Coyote played a significant role in Mesoamerican cosmology. The coyote symbolized military might in Mesoamerican chronology#Classic Era, Classic era Teotihuacan, with warriors dressing up in coyote costumes to call upon its predatory power. The species continued to be linked to Central Mexican warrior cults in the centuries leading up to the post-Classic Aztec rule.Schwartz, M. (1998). ''A History of Dogs in the Early Americas''. Yale University Press. pp. 146–149. .
In Aztec mythology, Huehuecoyotl, Huehuecóyotl (meaning "old coyote"), the god of dance, music and carnality, is depicted in several codices as a man with a coyote's head. He is sometimes depicted as a Promiscuity, womanizer, responsible for bringing war into the world by seducing Xochiquetzal, the goddess of love. Epigraphy, Epigrapher David H. Kelley argued that the god Quetzalcoatl owed its origins to pre-Aztec Uto-Aztecan languages, Uto-Aztecan mythological depictions of the coyote, which is portrayed as mankind's "Elder Brother", a creator, seducer, trickster, and culture hero linked to the morning star.
Attacks on humans
Coyote attacks on humans are uncommon and rarely cause serious injuries, due to the relatively small size of the coyote, but have been increasingly frequent, especially in California. There have been only two confirmed fatal attacks: one on a three-year-old named Kelly Keen coyote attack, Kelly Keen in Glendale, California and another on a nineteen-year-old named Taylor Mitchell in Nova Scotia, Canada. In the 30 years leading up to March 2006, at least 160 attacks occurred in the United States, mostly in the Los Angeles County area. Data from United States Department of Agriculture (USDA) Wildlife Services, the California Department of Fish and Game, and other sources show that while 41 attacks occurred during the period of 1988–1997, 48 attacks were verified from 1998 through 2003. The majority of these incidents occurred in Southern California near the suburban-wildland interface.
In the absence of the harassment of coyotes practiced by rural people, urban coyotes are losing their fear of humans, which is further worsened by people intentionally or unintentionally feeding coyotes. In such situations, some coyotes have begun to act aggressively toward humans, chasing joggers and bicyclists, confronting people walking their dogs, and stalking small children. Non-rabid coyotes in these areas sometimes target small children, mostly under the age of 10, though some adults have been bitten.
Although media reports of such attacks generally identify the animals in question as simply "coyotes", research into the genetics of the eastern coyote indicates those involved in attacks in northeast North America, including Pennsylvania, New York, New England, and eastern Canada, may have actually been Coywolf, coywolves, hybrids of ''Canis latrans'' and ''C. lupus,'' not fully coyotes.
Livestock and pet predation
, coyotes were the most abundant livestock predators in western North America, causing the majority of sheep, goat, and cattle losses. For example, according to the National Agricultural Statistics Service, coyotes were responsible for 60.5% of the 224,000 sheep deaths attributed to predation in 2004. The total number of sheep deaths in 2004 comprised 2.22% of the total sheep and lamb population in the United States, which, according to the National Agricultural Statistics Service USDA report, totaled 4.66 million and 7.80 million heads respectively as of July 1, 2005.
Because coyote populations are typically many times greater and more widely distributed than those of wolves, coyotes cause more overall predation losses. United States government agents routinely shoot, poison, trap, and kill about 90,000 coyotes each year to protect livestock. An Idaho census taken in 2005 showed that individual coyotes were 5% as likely to attack livestock as individual wolves. In Utah, more than 11,000 coyotes were killed for bounties totaling over $500,000 in the fiscal year ending June 30, 2017.
Livestock guardian dogs are commonly used to aggressively repel predators and have worked well in both fenced pasture and range operations. A 1986 survey of sheep producers in the USA found that 82% reported the use of dogs represented an economic asset.
Re-wilding cattle, which involves increasing the natural protective tendencies of cattle, is a method for controlling coyotes discussed by Temple Grandin of Colorado State University. This method is gaining popularity among producers who allow their herds to calve on the range and whose cattle graze open pastures throughout the year.
Coyotes typically Throat clamp, bite the throat just behind the jaw and below the ear when attacking adult sheep or goats, with death commonly resulting from suffocation. Blood loss is usually a secondary cause of death. Calves and heavily fleeced sheep are killed by attacking the flanks or hindquarters, causing shock and blood loss. When attacking smaller prey, such as young lambs, the kill is made by biting the skull and spinal regions, causing massive tissue and bone damage. Small or young prey may be completely carried off, leaving only blood as evidence of a kill. Coyotes usually leave the hide and most of the skeleton of larger animals relatively intact, unless food is scarce, in which case they may leave only the largest bones. Scattered bits of wool, skin, and other parts are characteristic where coyotes feed extensively on larger carcasses.
Tracks are an important factor in distinguishing coyote from dog predation. Coyote tracks tend to be more oval-shaped and compact than those of domestic dogs, and their claw marks are less prominent and the tracks tend to follow a straight line more closely than those of dogs. With the exception of sighthounds, most dogs of similar weight to coyotes have a slightly shorter stride. Coyote kills can be distinguished from wolf kills by less damage to the underlying tissues in the former. Also, coyote scat tends to be smaller than wolf scat.
Coyotes are often attracted to dog food and animals that are small enough to appear as prey. Items such as garbage, pet food, and sometimes feeding stations for birds and squirrels attract coyotes into backyards. About three to five pets attacked by coyotes are brought into the Animal Urgent Care hospital of South Orange County (California) each week, the majority of which are dogs, since cats typically do not survive the attacks. Scat analysis collected near Claremont, California, revealed that coyotes relied heavily on pets as a food source in winter and spring.
At one location in Southern California, coyotes began relying on a colony of feral cats as a food source. Over time, the coyotes killed most of the cats and then continued to eat the cat food placed daily at the colony site by people who were maintaining the cat colony.
Coyotes usually attack smaller-sized dogs, but they have been known to attack even large, powerful breeds such as the Rottweiler in exceptional cases. Dogs larger than coyotes, such as greyhounds, are generally able to drive them off and have been known to kill coyotes. Smaller breeds are more likely to suffer injury or death.
Hunting
Coyote hunting is one of the most common forms of predator hunting that humans partake in. There are not many regulations with regard to the taking of the coyote which means there are many different methods that can be used to hunt the animal. The most common forms are trapping, Imitation, calling, and Dog, hound hunting. Since coyotes are colorblind, seeing only in shades of gray and subtle blues, open camouflages, and plain patterns can be used. As the average male coyote weighs 8 to 20 kg (18 to 44 lbs) and the average female coyote 7 to 18 kg (15 to 40 lbs), a universal projectile that can perform between those weights is the .223 Remington, so that the projectile expands in the target after entry, but before the exit, thus delivering the most energy.
Coyotes being the light and agile animals they are, they often leave a very light impression on terrain. The coyote's footprint is oblong, approximately 6.35 cm (2.5-inches) long and 5.08 cm (2-inches) wide. There are four claws in both their front and hind paws. The coyote's center pad is relatively shaped like that of a rounded triangle. Like the domestic dog the coyote's front paw is slightly larger than the hind paw. The coyote's paw is most similar to that of the domestic dog.
Fur uses
Prior to the mid-19th century, coyote fur was considered worthless. This changed with the diminution of North American beaver, beavers, and by 1860, the hunting of coyotes for their fur became a great source of income (75 Penny (United States coin), cents to United States dollar, $1.50 per skin) for wolfers (hunting), wolfers in the Great Plains. Coyote pelts were of significant economic importance during the early 1950s, ranging in price from $5 to $25 per pelt, depending on locality. The coyote's fur is not durable enough to make rugs, but can be used for coats and jackets, scarves, or muffs. The majority of pelts are used for making Trim (sewing), trimmings, such as coat collars and sleeves for women's clothing. Coyote fur is sometimes dyed black as imitation Silver fox (animal), silver fox.
Coyotes were occasionally eaten by trappers and mountain men during the Manifest destiny, western expansion. Coyotes sometimes featured in the feasts of the Plains Indians, and coyote pups were eaten by the indigenous people of San Gabriel, California. The taste of coyote meat has been likened to that of the wolf and is more tender than pork when boiled. Coyote fat, when taken in the fall, has been used on occasion to grease leather or eaten as a Spread (food), spread.
Tameability
Coyotes were likely semidomesticated by various pre-Columbian cultures. Some 19th-century writers wrote of coyotes being kept in native villages in the Great Plains. The coyote is easily tamed as a pup, but can become destructive as an adult. Both full-blooded and hybrid coyotes can be playful and confiding with their owners, but are suspicious and shy of strangers, though coyotes being tractable enough to be used for practical purposes like Retriever, retrieving and Pointing breed, pointing have been recorded. A tame coyote named "Butch", caught in the summer of 1945, had a short-lived career in Film, cinema, appearing in ''Smoky (1946 film), Smoky'' (1946) and ''Ramrod (film), Ramrod'' (1947) before being shot while raiding a henhouse.In popular media
