Klamath National Wildlife Refuges Complex
The Lower Klamath National Wildlife Refuge is a National Wildlife Refuge of the United States on the border between California and Oregon. It is operated by the United States Fish and Wildlife Service. The refuge was designated a National Historic Landmark on October 16, 1965. Lower Klamath National Wildlife Refuge, established by President Theodore Roosevelt in 1908, was the first waterfowl refuge in the United States. It is located in the Klamath Basin near Klamath Falls, Oregon. It has a total area of , of which are in California and are in Oregon. The refuge includes shallow freshwater marshes, open water, grassy uplands, and croplands that are intensively managed to provide foraging and breeding habitat for waterfowl and other animals. The market hunting of migratory birds in the late 19th century created the need for preservation and creation of a wildlife refuge. Refuge objectives include the protection of habitat for flora and fauna, including migrating waterfowl, and pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siskiyou County, California
Siskiyou County (, ) is a county in the northernmost part of the U.S. state of California. As of the 2020 census, the population was 44,076. Its county seat is Yreka and its highest point is Mount Shasta. It falls within the Cascadia bioregion. Siskiyou County is in the Shasta Cascade region along with the Oregon border. Because of its outdoor recreation, Mt. Shasta, McCloud River, and Gold Rush era history, it is an important tourist destination within the state. History Siskiyou County was created on March 22, 1852, from parts of Shasta and Klamath Counties, and named after the Siskiyou mountain range. Parts of the county's territory were given to Modoc County in 1855. The county is the site of the central section of the Siskiyou Trail, which ran between California's Central Valley and the Pacific Northwest. The Siskiyou Trail followed Native American footpaths, and was extended by Hudson's Bay Company trappers in the 1830s. Its length was increased by " Forty-Niners" ...

Bald Eagle
The bald eagle (''Haliaeetus leucocephalus'') is a bird of prey found in North America. A sea eagle, it has two known subspecies and forms a species pair with the white-tailed eagle (''Haliaeetus albicilla''), which occupies the same niche as the bald eagle in the Palearctic. Its range includes most of Canada and Alaska, all of the contiguous United States, and northern Mexico. It is found near large bodies of open water with an abundant food supply and old-growth trees for nesting. The bald eagle is an opportunistic feeder which subsists mainly on fish, which it swoops down upon and snatches from the water with its talons. It builds the largest nest of any North American bird and the largest tree nests ever recorded for any animal species, up to deep, wide, and in weight. Sexual maturity is attained at the age of four to five years. Bald eagles are not actually bald; the name derives from an older meaning of the word, "white headed". The adult is mainly brown with a white ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Grebe
The western grebe (''Aechmophorus occidentalis'') is a species in the grebe family of water birds. Folk names include "dabchick", "swan grebe" and "swan-necked grebe". Western grebe fossils from the Late Pleistocene of southwest North America were described as a distinct species, but later ranked as a paleosubspecies ''Aechmophorus occidentalis lucasi''. More recent study found them to fall within the variation now known to exist in today's birds. Description The western grebe is the largest North American grebe. It is long, weighs and measures across the wings.''CRC Handbook of Avian Body Masses'' by John B. Dunning Jr. (Editor). CRC Press (1992), .Burnie D and Wilson DE (Eds.), ''Animal: The Definitive Visual Guide to the World's Wildlife''. DK Adult (2005), It is black-and-white, with a long, slender, swan-like neck and red eyes. It is easily confused with Clark's grebe, which shares similar features, body size, behavior and habitat, and Hybrid (biology), hybrids are known ...

Canvasback
The canvasback (''Aythya valisineria'') is a species of diving duck, the largest found in North America. Taxonomy Scottish-American naturalist Alexander Wilson described the canvasback in 1814. The genus name is derived from Greek ''aithuia'', an unidentified seabird mentioned by authors, including Hesychius and Aristotle. The species name ''valisineria'' comes from the wild celery ''Vallisneria americana'', whose winter buds and rhizomes are the canvasback's preferred food during the nonbreeding period. The celery genus is itself named for seventeenth century Italian botanist Antonio Vallisneri. The duck's common name is based on early European inhabitants of North America's assertion that its back was a canvas-like color. In other languages it is just a ''white-backed duck''; for example in French, ''morillon à dos blanc'', or Spanish, ''pato lomo blanco''. In Mexico it is called ''pato coacoxtle''. Description It ranges from in length and weighs , with a wingspan of . ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gadwall
The gadwall (''Mareca strepera'') is a common and widespread dabbling duck in the family Anatidae. Taxonomy The gadwall was first described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae''. DNA studies have shown that it is a sister species with the falcated duck; the two are closely related to the three species of wigeons, and all of them have been assigned to the genus ''Mareca''. There are two subspecies: * ''M. s. strepera'', the common gadwall, described by Linnaeus, is the nominate subspecies. * ''M. s. couesi'', Coues's gadwall, extinct 1874, was formerly found only on Teraina, a coral atoll in the Pacific Ocean. The specific name ''strepera'' is Late Latin for "noisy". The etymology of the word ''gadwall'' is not known, but the name has been in use since 1666. Description The gadwall is long with a wingspan. The male is slightly larger than the female, weighing on average against her . The breeding male is patterned grey, with a black re ...

Mallard
The mallard () or wild duck (''Anas platyrhynchos'') is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa, and has been introduced to New Zealand, Australia, Peru, Brazil, Uruguay, Argentina, Chile, Colombia, the Falkland Islands, and South Africa. This duck belongs to the subfamily Anatinae of the waterfowl family Anatidae. Males have purple patches on their wings, while the females (hens or ducks) have mainly brown-speckled plumage. Both sexes have an area of white-bordered black or iridescent blue feathers called a speculum on their wings; males especially tend to have blue speculum feathers. The mallard is long, of which the body makes up around two-thirds the length. The wingspan is and the bill is long. It is often slightly heavier than most other dabbling ducks, weighing . Mallards live in wetlands, eat water plants and small animals, and are social animals preferring to congregate in groups or flocks of varyi ...

Northern Pintail
The pintail or northern pintail (''Anas acuta'') is a duck species with wide geographic distribution that breeds in the northern areas of Europe and across the Palearctic and North America. It is migratory and winters south of its breeding range to the equator. Unusually for a bird with such a large range, it has no geographical subspecies if the possibly conspecific duck Eaton's pintail is considered to be a separate species. This is a large duck, and the male's long central tail feathers give rise to the species' English and scientific names. Both sexes have blue-grey bills and grey legs and feet. The drake is more striking, having a thin white stripe running from the back of its chocolate-coloured head down its neck to its mostly white undercarriage. The drake also has attractive grey, brown, and black patterning on its back and sides. The hen's plumage is more subtle and subdued, with drab brown feathers similar to those of other female dabbling ducks. Hens make a coarse ...

Peregrine Falcon
The peregrine falcon (''Falco peregrinus''), also known as the peregrine, and historically as the duck hawk in North America, is a Cosmopolitan distribution, cosmopolitan bird of prey (Bird of prey, raptor) in the family (biology), family Falconidae. A large, Corvus (genus), crow-sized falcon, it has a blue-grey back, barred white underparts, and a black head. The peregrine is renowned for its speed, reaching over during its characteristic hunting stoop (high-speed dive), making it the fastest bird in the world, as well as the Fastest animals, fastest member of the animal kingdom. According to a ''National Geographic (U.S. TV channel), National Geographic'' TV program, the highest measured speed of a peregrine falcon is . As is typical for avivore, bird-eating raptors, peregrine falcons are Sexual dimorphism, sexually dimorphic, with females being considerably larger than males. The peregrine's breeding range includes land regions from the Arctic tundra to the tropics. It can b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canada Goose
The Canada goose (''Branta canadensis''), or Canadian goose, is a large wild goose with a black head and neck, white cheeks, white under its chin, and a brown body. It is native to the arctic and temperate regions of North America, and it is occasionally found during migration across the Atlantic in northern Europe. It has been introduced to the United Kingdom, Ireland, Finland, Sweden, Denmark, New Zealand, Japan, Chile, Argentina, and the Falkland Islands. Like most geese, the Canada goose is primarily herbivorous and normally migratory; often found on or close to fresh water, the Canada goose is also common in brackish marshes, estuaries, and lagoons. Extremely adept at living in human-altered areas, Canada geese have established breeding colonies in urban and cultivated habitats, which provide food and few natural predators. The success of this common park species has led to its often being considered a pest species because of its excrement, its depredation of crops, its n ...

Greater White-fronted Goose
The greater white-fronted goose (''Anser albifrons'') is a species of goose related to the smaller lesser white-fronted goose (''A. erythropus''). It is named for the patch of white feathers bordering the base of its bill, in fact ''albifrons ''comes from the Latin ''albus'' "white" and ''frons "''forehead". In Europe it has been known as the white-fronted goose; in North America it is known as the greater white-fronted goose (or "greater whitefront"), and this name is also increasingly adopted internationally. Even more distinctive are the salt-and-pepper markings on the breast of adult birds, which is why the goose is colloquially called the "specklebelly" in North America. Description Greater white-fronted geese are in length, have a wingspan, and weigh . They have bright orange legs and mouse-coloured upper wing-coverts. They are smaller than greylag geese. As well as being larger than the lesser white-fronted goose, the greater white-fronted goose lacks the yellow eye-r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ross's Goose
The Ross's goose (''Anser rossii'') is a white goose with black wingtips and a relatively short neck. It is the smallest of the three " white geese" that breed in North America. It is similar in appearance to a white-phase snow goose, but about 40% smaller. Other differences from the snow goose are that the bill is smaller in proportion to its body and lacks "black lips". The dark phase is extremely rare. Before the early 1900s, this goose was considered a rare species, possibly as a consequence of open hunting, but numbers have increased dramatically as a result of conservation measures. It is now listed as a species of Least Concern by the IUCN, and is protected by the Migratory Bird Treaty Act. The Ross's goose is named in honor of Bernard R. Ross, who was associated with the Hudson's Bay Company in Canada's Northwest Territories. Members of the Hudson's Bay Company were the first Europeans to discover the arctic nesting grounds of Ross's geese in 1940. The first recognizabl ...

Snow Goose
The snow goose (''Anser caerulescens'') is a species of goose native to North America. Both white and dark morphs exist, the latter often known as blue goose. Its name derives from the typically white plumage. The species was previously placed in the genus ''Chen'', but is now typically included in the "gray goose" genus ''Anser''. Snow geese breed north of the timberline in Greenland, Canada, Alaska, and the northeastern tip of Siberia, and spend winters in warm parts of North America from southwestern British Columbia through parts of the United States to Mexico. Snow goose populations increased dramatically in the 20th century. Taxonomy In 1750 the English naturalist George Edwards included an illustration and a description of the snow goose in the third volume of his ''A Natural History of Uncommon Birds''. He used the English name "The blue-winged goose". Edwards based his hand-coloured etching on a preserved specimen that had been brought to London from the Hudson Bay a ...
