The mountain goat (Oreamnos americanus) is a large North American hoofed mammal native to steep, rugged mountain habitats. Despite its name, it is not a true goat but a goat-antelope in the family Bovidae. It is known for its white coat and climbing ability, with most of its range in British Columbia and Alaska.

Taxonomy and classification

The mountain goat is Oreamnos americanus, the only living species in its genus. It belongs to the family Bovidae and is more closely described as a goat-antelope than a true goat.

Physical characteristics

Mountain goats are stocky, white-coated mammals with black, slightly curved horns. Their thick fur and compact build help them cope with cold temperatures and exposed alpine conditions.

Range and habitat

The species lives in western North America, especially in mountainous regions from Alaska and the Yukon to parts of the northern Rocky Mountains and the Cascades. It is associated with cliffs, ledges, and other rugged terrain. Canada, particularly British Columbia, holds a large share of the natural range, and the species is also found in the Yukon.

Behaviour and diet

Mountain goats are herbivores that browse and graze on a variety of alpine plants, including grasses, herbs, mosses, lichens, shrubs, and some conifers. They are known for strong climbing ability and for using steep terrain as refuge from predators. Females usually live in small groups, while adult males are often solitary.

Conservation status

The species is listed as Least Concern. Populations are widespread, though local numbers can vary and some introduced populations occur outside the native range.

Key facts

  • Mountain goats are not true goats; they are goat-antelopes in the bovid family.
  • Their white, shaggy coat helps them survive cold alpine conditions.
  • They are adapted to steep, rocky terrain and are known for sure-footed climbing.
  • They eat grasses, herbs, mosses, lichens, shrubs, and some conifers.
  • Females usually live in small groups, while adult males are often solitary.

Canadian context

Mountain goats are strongly associated with Canada, especially British Columbia, which holds a large share of the species’ natural range. They are also found in parts of the Yukon, making them a notable Canadian alpine mammal.
