The moose or elk is the world's tallest, largest and heaviest extant species of deer and the only species in the genus Alces. It is also the tallest, and the second-largest, land animal in North America, falling short only of the American bison in body mass. Most adult male moose have broad, palmate antlers; other members of the deer family have pointed antlers with a dendritic ("twig-like") configuration. Moose inhabit the circumpolar boreal forests or temperate broadleaf and mixed forests of the Northern Hemisphere, thriving in cooler, temperate areas as well as subarctic climates.
The golden eagle is a bird of prey living in the Northern Hemisphere. It is the most widely distributed species of eagle. Like all eagles, it belongs to the family Accipitridae. They are one of the best-known birds of prey in the Northern Hemisphere. These birds are dark brown, with lighter golden-brown plumage on their napes. Immature eagles of this species typically have white on the tail and often have white markings on the wings. Golden eagles use their agility and speed combined with powerful feet and large, sharp talons to hunt a variety of prey, mainly hares, rabbits, and marmots and other ground squirrels. Golden eagles maintain home ranges or territories that may be as large as 200 km2 (77 sq mi). They build large nests in cliffs and other high places to which they may return for several breeding years. Most breeding activities take place in the spring; they are monogamous and may remain together for several years or possibly for life. Females lay up to four eggs, and then incubate them for six weeks. Typically, one or two young survive to fledge in about three months. These juvenile golden eagles usually attain full independence in the fall, after which they wander widely until establishing a territory for themselves in four to five years.
The eastern grey kangaroo is a marsupial found in the eastern third of Australia, with a population of several million. It is also known as the great grey kangaroo and the forester kangaroo. Although a big eastern grey male can typically weigh up to 69 kg (152 lb) and have a length of well over 2 m, the scientific name, Macropus giganteus, is misleading: the red kangaroo of the semi-arid inland is larger, weighing up to 90 kg (200 lb).
The grey seal is a large seal of the family Phocidae, which are commonly referred to as "true seals" or "earless seals". The only species classified in the genus Halichoerus, it is found on both shores of the North Atlantic Ocean. In Latin, Halichoerus grypus means "hook-nosed sea pig". Its name is spelled gray seal in the United States; it is also known as Atlantic seal and the horsehead seal.
The argali, also known as the mountain sheep, is a wild sheep native to the highlands of western East Asia, the Himalayas, Tibet, and the Altai Mountains.
The East Caucasian tur, also known as the Daghestani tur, is a mountain-dwelling caprine living in the eastern half of the Greater Caucasus mountains, in Azerbaijan, Georgia, and European Russia. It inhabits rough mountainous terrain, where it eats mainly grasses and leaves. It is listed as near threatened on the IUCN Red List.
The greater rhea is a species of flightless bird native to eastern South America. Other names for the greater rhea include the grey, common, or American rhea; ema (Portuguese); or ñandú. One of two species in the genus Rhea, in the family Rheidae, it inhabits a variety of open areas, such as grasslands, savanna or grassy wetlands. Weighing 20–27 kilograms (44–60 lb), the greater rhea is the largest native bird in the Americas. In the wild, the greater rhea has a life expectancy of 10.5 years. It is also notable for its reproductive habits, and for the fact that a population has established itself in Northern Germany in recent years. The species is listed as Near Threatened by the IUCN.
The giant forest hog, the only member of its genus (Hylochoerus), is native to wooded habitats in Africa and is one of the largest wild members of the pig family, Suidae, along with a few subspecies of the wild boar. It was first described in 1904. The specific name honours Richard Meinertzhagen, who shot the type specimen in Kenya and had it shipped to the Natural History Museum in England.
The Ugandan kob is a subspecies of the kob, a type of antelope. It is found in sub-Saharan Africa in South Sudan, Uganda and the Democratic Republic of the Congo. The Ugandan kob is normally reddish-brown, differentiating it from other kob subspecies.
The elk, or wapiti, is the second largest species within the deer family, Cervidae, and one of the largest terrestrial mammals in its native range of North America and Central and East Asia. The word "elk" originally referred to the European variety of the moose, Alces alces, but was transferred to Cervus canadensis by North American colonists.
The New England-Acadian forests are a temperate broadleaf and mixed forest ecoregion in North America that includes a variety of habitats on the hills, mountains and plateaus of New England and New York State in the Northeastern United States, and Quebec and the Maritime Provinces of Eastern Canada.
The Eastern Canadian Boreal Forests is a boreal ecoregion in Eastern Canada, defined by the One Earth ecoregion categorization system.
The Alaska moose, or Alaskan moose in Alaska, or giant moose and Yukon moose in Canada, is a subspecies of moose that ranges from Alaska to western Yukon. The Alaska moose is the largest subspecies of moose. Alaska moose inhabit boreal forests and mixed deciduous forests throughout most of Alaska and most of Western Yukon. Like all moose subspecies, the Alaska moose is usually solitary but sometimes will form small herds. Typically, they only come into contact with other moose for mating or competition for mates. Males and females select different home ranges during different seasons. This leads to spatial segregation throughout much of the year. While males and females are spatially separate the habitat that they occupy is not significantly different. During mating season, in autumn and winter, male Alaska moose become very aggressive and prone to attacking when startled.
The Western moose is a subspecies of moose that inhabits boreal forests and mixed deciduous forests in the Canadian Arctic, western Canadian provinces and a few western sections of the northern United States. It is the second largest North American subspecies of moose, second to the Alaskan moose. This subspecies is prey to timber wolves and bears. Male Western moose are aggressive during mating season and may injure or kill with provocation.
Cervalces latifrons, the broad-fronted moose, or the giant moose was a giant species of deer that inhabited Europe and Asia during the Pleistocene epoch. It is thought to be the ancestor of the modern moose, as well as the extinct North American Cervalces scotti. It was considerably larger than living moose, placing it as one of the largest deer to have ever lived.
The eastern coyote is a wild North American canine hybrid with both coyote and wolf parentage. The hybridization likely first occurred in the Great Lakes region, as western coyotes moved east. It was first noticed during the early 1930s to the late 1940s, and likely originated in the aftermath of the extirpation of the gray wolf and eastern wolf in southeastern Ontario, Labrador and Quebec; this allows coyotes to colonize the former wolf ranges, and mix with the remnant wolf populations. This hybrid is smaller than the eastern wolf and holds smaller territories, but is larger and holds more extensive home ranges than the typical western coyote.
Dermacentor albipictus, the winter tick, is a species of hard tick that parasitizes many different mammal species in North America. It is commonly associated with cervid species such as elk, white-tailed deer, mule deer and caribou but is primarily known as a serious pest of moose. As early as 1909, Ernest Thompson Seton described the winter tick as a greater enemy of the moose than were "wolves, bears, and cougars."
The Northwest Territories taiga ecoregion (WWF:NA0614) is located in the Northwest Territories and Yukon provinces of Canada. It covers forest and tundra along the Mackenzie River Valley and the surrounding highlands in the southern portion of the valley.
