Domestic Sheep Predation
Along with parasites and disease, predation is a threat to sheep health and consequently to the profitability of sheep raising. Sheep have very little ability to defend themselves, even when compared with other prey species kept as livestock. Even if sheep are not directly bitten or survive an attack, they may die from panic or from injuries sustained. However, the impact of predation varies dramatically with region. In Africa, Australia, the Americas, and parts of Europe and Asia predators can be a serious problem. In contrast, some nations are virtually devoid of sheep predators. Many islands that are known for extensive sheep husbandry are suitable largely because of their predator-free status. Worldwide, canids—including the domestic dog—are responsible for the majority of sheep deaths. Other animals that prey on sheep include but are not limited to: felines, birds of prey, and feral hogs. Relation to sheep behavior Sheep flight behavior is cited in one major st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coyotes
The coyote (''Canis latrans'') is a species of canis, canine native to North America. It is smaller than its close relative, the wolf, and slightly smaller than the closely related eastern wolf and red wolf. It fills much of the same ecological niche as the golden jackal does in Eurasia. The coyote is larger and more predatory and was once referred to as the American jackal by a behavioral ecologist. Other historical names for the species include the prairie wolf and the brush wolf. The coyote is listed as Least Concern, least concern by the International Union for Conservation of Nature, due to its wide distribution and abundance throughout North America. The species is versatile, able to adapt to and expand into environments modified by humans. It is enlarging its range by moving into urban areas in the eastern U.S. and Canada. The coyote was sighted in eastern Panama (across the Panama Canal from their home range) for the first time in 2013. The coyote has 19 recognized sub ...

Culpeo
The culpeo (''Lycalopex culpaeus''), also known as culpeo zorro, Andean zorro, Andean fox, Paramo wolf, Andean wolf,Comparative ecology of two South American foxes, 'Dusicvon ariseus' and 'culpaeus' by Warren E. Johnson. Doctoral dissertation. Iowa State University; 1992. p2. Accessed July 10, 2021 at https://lib.dr.iastate.edu/cgi/viewcontent.cgi?article=11006&context=rtd and colpeo fox, is a species of South American fox. Regardless of the name, it is not a true fox, but more closely related to wolves and jackals. Its appearance resembles that of foxes due to convergent evolution. It is the second-largest native canid on the continent after the maned wolf. In appearance, it bears many similarities to the widely recognized red fox. It has grey and reddish fur, a white chin, reddish legs and a stripe on its back that may be barely visible. The culpeo's diet consists largely of rodents, rabbits, birds and lizards, and to a lesser extent, plant material and carrion. The culpeo doe ...

Pseudalopex
The South American foxes (''Lycalopex''), commonly called ''raposa'' in Portuguese language, Portuguese, or ''zorro'' in Spanish language, Spanish, are a genus from South America of the subfamily Caninae. Despite their name, they are not Vulpes, true foxes, but are a unique canid genus more closely related to wolves and jackals than to true foxes; some of them resemble foxes due to convergent evolution. The South American gray fox, ''Lycalopex griseus'', is the most common species, and is known for its large ears and a highly marketable, russet-fringed Fur, pelt. The second-oldest known fossils belonging to the genus were discovered in Chile, and date from 2.0 to 2.5 million years ago, in the mid- to late Pliocene. The Vorohué Formation of Argentina has provided older fossils, dating to the Uquian to Ensenadan (Late Pliocene). [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maned Wolf
The maned wolf (''Chrysocyon brachyurus'') is a large canine of South America. It is found in Argentina, Brazil, Bolivia, Peru, and Paraguay, and is almost extinct in Uruguay. Its markings resemble those of foxes, but it is neither a fox nor a wolf. It is the only species in the genus ''Chrysocyon'' (meaning "golden dog"). It is the largest canine in South America, weighing and up to at the withers. Its long, thin legs and dense reddish coat give it an unmistakable appearance. The maned wolf is a crepuscular and omnivorous animal adapted to the open environments of the South American savanna, with an important role in the seed dispersal of fruits, especially the wolf apple (''Solanum lycocarpum''). The maned wolf is a solitary animal. It communicates primarily by scent marking, but also gives a loud call known as "roar-barking". This mammal lives in open and semi-open habitats, especially grasslands with scattered bushes and trees, in the Cerrado of south, central-west, and ...

Jaguar
The jaguar (''Panthera onca'') is a large cat species and the only living member of the genus '' Panthera'' native to the Americas. With a body length of up to and a weight of up to , it is the largest cat species in the Americas and the third largest in the world. Its distinctively marked coat features pale yellow to tan colored fur covered by spots that transition to rosettes on the sides, although a melanistic black coat appears in some individuals. The jaguar's powerful bite allows it to pierce the carapaces of turtles and tortoises, and to employ an unusual killing method: it bites directly through the skull of mammalian prey between the ears to deliver a fatal blow to the brain. The modern jaguar's ancestors probably entered the Americas from Eurasia during the Early Pleistocene via the land bridge that once spanned the Bering Strait. Today, the jaguar's range extends from core Southwestern United States across Mexico and much of Central America, the Amazon rainfo ...

New World Vulture
The New World vulture or condor family, Cathartidae, contains seven extant species in five genera. It includes five extant vultures and two extant condors found in warm and temperate areas of the Americas. The "New World" vultures were widespread in both the Old World and North America during the Neogene. Old World vultures and New World vultures do not form a single clade, but the two groups are similar in appearance due to convergent evolution. Vultures are scavenging birds, feeding mostly from carcasses of dead animals without apparent ill effects. Bacteria in the food source, pathogenic to other vertebrates, dominate the vulture's gut flora, and vultures benefit from the bacterial breakdown of carrion tissue. Some species of New World vulture have a good sense of smell, whereas Old World vultures find carcasses exclusively by sight. A particular characteristic of many vultures is a bald head, devoid of feathers. Taxonomy and systematics The New World vultures comprise seven ...

Raven
A raven is any of several larger-bodied bird species of the genus ''Corvus''. These species do not form a single taxonomic group within the genus. There is no consistent distinction between "crows" and "ravens", common names which are assigned to different species chiefly on the basis of their size. The largest raven species are the common raven and the thick-billed raven. Etymology The term "raven" originally referred to the common raven (''Corvus corax''), the type species of the genus ''Corvus'', which has a larger distribution than any other species of ''Corvus'', ranging over much of the Northern Hemisphere. The modern English word ''raven'' has cognates in all other Germanic languages, including Old Norse (and subsequently modern Icelandic) and Old High German , all of which descend from Proto-Germanic . Collective nouns for a group of ravens (or at least the common raven) include "rave", "treachery", "unkindness" and "conspiracy". In practice, most people use the more ...

Wolves
The wolf (''Canis lupus''; plural, : wolves), also known as the gray wolf or grey wolf, is a large Canis, canine native to Eurasia and North America. More than thirty subspecies of Canis lupus, subspecies of ''Canis lupus'' have been recognized, and gray wolves, as popularly understood, comprise wild subspecies. The wolf is the largest Neontology, extant member of the family Canidae. It is also distinguished from other ''Canis'' species by its less pointed ears and muzzle, as well as a shorter torso and a longer tail. The wolf is nonetheless related closely enough to smaller ''Canis'' species, such as the coyote and the golden jackal, to produce fertile Canid hybrid, hybrids with them. The Agouti (coloration), banded fur of a wolf is usually mottled white, brown, gray, and black, although subspecies in the arctic region may be nearly all white. Of all members of the genus ''Canis'', the wolf is most Generalist and specialist species, specialized for Pack hunter, cooperativ ...

Bear
Bears are carnivoran mammals of the family Ursidae. They are classified as caniforms, or doglike carnivorans. Although only eight species of bears are extant, they are widespread, appearing in a wide variety of habitats throughout the Northern Hemisphere and partially in the Southern Hemisphere. Bears are found on the continents of North America, South America, Europe, and Asia. Common characteristics of modern bears include large bodies with stocky legs, long snouts, small rounded ears, shaggy hair, plantigrade paws with five nonretractile claws, and short tails. While the polar bear is mostly carnivorous, and the giant panda feeds almost entirely on bamboo, the remaining six species are omnivorous with varied diets. With the exception of courting individuals and mothers with their young, bears are typically solitary animals. They may be diurnal or nocturnal and have an excellent sense of smell. Despite their heavy build and awkward gait, they are adept runners, cli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eagle
Eagle is the common name for many large birds of prey of the family Accipitridae. Eagles belong to several groups of genera, some of which are closely related. Most of the 68 species of eagle are from Eurasia and Africa. Outside this area, just 14 species can be found—2 in North America, 9 in Central and South America, and 3 in Australia. Eagles are not a natural group but denote essentially any kind of bird of prey large enough to hunt sizeable (about 50 cm long or more overall) vertebrates. Description Eagles are large, powerfully-built birds of prey, with heavy heads and beaks. Even the smallest eagles, such as the booted eagle (''Aquila pennata''), which is comparable in size to a common buzzard (''Buteo buteo'') or red-tailed hawk (''B. jamaicensis''), have relatively longer and more evenly broad wings, and more direct, faster flight – despite the reduced size of aerodynamic feathers. Most eagles are larger than any other raptors apart from some vultures. The smalles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bobcat
The bobcat (''Lynx rufus''), also known as the red lynx, is a medium-sized cat native to North America. It ranges from southern Canada through most of the contiguous United States to Oaxaca in Mexico. It is listed as Least Concern on the IUCN Red List since 2002, due to its wide distribution and large population. Although it has been hunted extensively both for sport and fur, populations have proven stable, though declining in some areas. It has distinctive black bars on its forelegs and a black-tipped, stubby (or "bobbed") tail, from which it derives its name. It reaches a total length (including the tail) of up to . It is an adaptable predator inhabiting wooded areas, semidesert, urban edge, forest edge, and swampland environments. It remains in some of its original range, but populations are vulnerable to extirpation by coyotes and domestic animals. Though the bobcat prefers rabbits and hares, it hunts insects, chickens, geese and other birds, small rodents, and deer. Pre ...
