Mackenzie Valley Wolf
The northwestern wolf (''Canis lupus occidentalis''), also known as the Mackenzie Valley wolf, Alaskan timber wolf, or Canadian timber wolf, is a subspecies of gray wolf in western North America. Arguably the largest grey wolf subspecies in the world, it ranges from Alaska, the upper Mackenzie River Valley; southward throughout the western Canadian provinces, aside from prairie landscapes in its southern portions, as well as the Northwestern United States.Mech, L. David (1981), ''The wolf: The Ecology and Behaviour of an Endangered Species'', University of Minnesota Press, p. 352, Taxonomy This wolf is recognized as a subspecies of ''Canis lupus'' in the taxonomic authority ''Mammal Species of the World'' (2005). The subspecies was first written of by Scottish naturalist Sir John Richardson in 1829. He chose to give it the name ''occidentalis'' in reference to its geographic location rather than label it by its color, as it was too variable to warrant such.Richardson, J. (182 ...

John Richardson (naturalist)
Sir John Richardson Royal Society of London, FRS FRSE (5 November 1787 – 5 June 1865) was a Scotland, Scottish naval surgeon, natural history, naturalist and Arctic explorer. Life Richardson was born at Nith Place in Dumfries the son of Gabriel Richardson, Provost of Dumfries, and his wife, Anne Mundell. He was educated at Dumfries Grammar School. He was then apprenticed to his maternal uncle, Dr James Mundell, a surgeon in Dumfries. He studied medicine at Edinburgh University, and became a surgeon in the navy in 1807. He traveled with John Franklin in search of the Northwest Passage on the Coppermine Expedition of 1819–1822. Richardson wrote the sections on geology, botany and ichthyology for the official account of the expedition. Franklin and Richardson returned to Canada in 1825 and went overland by fur trade routes to the mouth of the Mackenzie River. Franklin was to go as far west as possible and Richardson was to go east to the mouth of the Coppermine River. These ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurasian Wolf
The Eurasian wolf (''Canis lupus lupus''), also known as the common wolf,Mech, L. David (1981), ''The Wolf: The Ecology and Behaviour of an Endangered Species'', University of Minnesota Press, p. 354, is a subspecies of grey wolf native to Europe and Asia. It was once widespread throughout Eurasia prior to the Middle Ages. Aside from an extensive paleontological record, Indo-European languages typically have several words for "wolf", thus attesting to the animal's abundance and cultural significance.Gamkrelidze, T. V. & Ivanov, V. V. (1995), ''Indo-European and the Indo-Europeans: A Reconstruction and Historical Analysis of a Proto-Language and Proto-Culture'', Walter de Gruyter, pp. 413-417, It was held in high regard in Baltic, Celtic, Slavic, Turkic, ancient Greek, Roman, and Thracian cultures, whilst having an ambivalent reputation in early Germanic cultures. It is the largest of Old World grey wolves, averaging in Europe; however, exceptionally large individuals have w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carnivorans Of North America
Carnivora is a monophyletic order of placental mammals consisting of the most recent common ancestor of all cat-like and dog-like animals, and all descendants of that ancestor. Members of this group are formally referred to as carnivorans, and have evolved to specialize in eating flesh. The order is the fifth largest order of mammals, comprising at least 279 species. Carnivorans live on every major landmass and in a variety of habitats, ranging from the cold polar regions to the hyper-arid region of the Sahara Desert to the open seas. They come in a very large array of different body plans in contrasting shapes and sizes. Carnivora can be divided into two subclades: the cat-like Feliformia and the dog-like Caniformia, which are differentiated based on the structure of their ear bones and cranial features. The feliforms include families such as the cats, the hyenas, the mongooses and the civets. The majority of feliform species are found in the Old World, though the cat ...

Woburn Safari Park
Woburn Safari Park is a safari park located in Woburn, Bedfordshire, England. Visitors to the park can drive through exhibits, which contain species such as southern white rhino, elephants, tigers and black bears. It is part of the estates of the Duke of Bedford that also includes Woburn Abbey and its deer park. The Safari Park itself covers .Woburn Safari: Finding Us' Retrieved 6 October 2014. Woburn Safari Park is a member of the British and Irish Association of Zoos and Aquariums (BIAZA) and the European Association of Zoos and Aquaria (EAZA). History Woburn Safari Park was opened in 1970, established by the 13th Duke of Bedford and Jimmy Chipperfield on the grounds of his estate, Woburn Abbey. This was done as a means to help improve the financial position of the estate and restore the Abbey, which had fallen into disrepair as a consequence of the second world war and relatively high post-war tax rates. The 11th Duke of Bedford had been president of the Zoological S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longleat Safari Park
Longleat Safari and Adventure Park in Wiltshire, England, was opened in 1966 as the world's first drive-through safari park outside Africa. History The park is situated in the grounds of Longleat House, an English stately home which is open to the public and is the home of the 8th Marquess of Bath. Longleat Safari Park and the concept of safari parks were the brainchild of Jimmy Chipperfield (1912–1990), former co-director of Chipperfield's Circus. In 2022, Longleat welcomed the birth of a southern koala joey. It is the first of its kind to be born in Europe. Description Longleat house and grounds Opened to the public in 1949, the ancestral home of the Marquess of Bath remains a popular attraction with visitors. Visitors can join one of the many regular house tours or simply walk about at their leisure. They may also explore the gardens surrounding the house and visit a number of cafés within the grounds. A separate ticket is sold for visitors who only wish to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plains Bison
The Plains bison (''Bison bison bison'') is one of two subspecies/ecotypes of the American bison, the other being the wood bison (''B. b. athabascae''). A natural population of Plains bison survives in Yellowstone National Park (the Yellowstone Park bison herd consisting of an estimated 4,800 bison) and multiple smaller reintroduced herds of bison in many places in the United States as well as southern portions of the Canadian Prairies. Near-extinction and reintroduction of herds At one time, at least 25 million American bison were spread across the United States and Canada. However, by the late 1880s, the total number of bison in the United States had been reduced to fewer than 600. Most of these were collected onto various private ranches, and the last known free-roaming population of bison consisted of fewer than 30 in the area which later became Yellowstone National Park. Although farmers and ranchers considered bison to be a nuisance, some people were concerned about the dem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coyote
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 ...

Grizzly Bear
The grizzly bear (''Ursus arctos horribilis''), also known as the North American brown bear or simply grizzly, is a population or subspecies of the brown bear inhabiting North America. In addition to the mainland grizzly (''Ursus arctos horribilis''), other morphological forms of brown bear in North America are sometimes identified as grizzly bears. These include three living populations—the Kodiak bear (''U. a. middendorffi''), the Kamchatka bear (''U. a. beringianus''), and the peninsular grizzly (''U. a. gyas'')—as well as the extinct California grizzly (''U. a. californicus''†), Mexican grizzly (formerly ''U. a. nelsoni''†), and Ungava-Labrador grizzly (formerly ''U. a. ungavaesis''†). On average, grizzly bears near the coast tend to be larger while inland grizzlies tend to be smaller. The Ussuri brown bear (''U. a. lasiotus''), inhabiting Russia, Northern China, Japan, and Korea, is sometimes referred to as the "black grizzly", although it is no more closely ...

American Black Bear
The American black bear (''Ursus americanus''), also called simply a black bear or sometimes a baribal, is a medium-sized bear endemic to North America. It is the continent's smallest and most widely distributed bear species. American black bears are omnivores, with their diets varying greatly depending on season and location. They typically live in largely forested areas, but will leave forests in search of food, and are sometimes attracted to human communities due to the immediate availability of food. The International Union for Conservation of Nature (IUCN) lists the American black bear as a least-concern species, due to its widespread distribution and a large population estimated to be twice that of all other bear species combined. Along with the brown bear (''Ursus arctos''), it is one of only two modern bear species not considered by the IUCN to be globally threatened with extinction. Taxonomy and evolution Despite living in North America, American black bears are not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Common Raven
The common raven (''Corvus corax'') is a large all-black passerine bird. It is the most widely distributed of all corvids, found across the Northern Hemisphere. It is a raven known by many names at the subspecies level; there are at least eight subspecies with little variation in appearance, although recent research has demonstrated significant genetic differences among populations from various regions. It is one of the two largest corvids, alongside the thick-billed raven, and is possibly the heaviest passerine bird; at maturity, the common raven averages in length and in mass. Although their typical lifespan is considerably shorter, common ravens can live more than 23 years in the wild. Young birds may travel in flocks but later mate for life, with each mated pair defending a territory. Common ravens have coexisted with humans for thousands of years and in some areas have been so numerous that people have regarded them as pests. Part of their success as a species is due ...
