Elk

The elk is a large deer species, known scientifically as *Cervus canadensis*.

Updated July 30, 20261 min readCited sources

The elk is a large deer species (*Cervus canadensis*) native to North America and parts of Asia. In Canada, the term refers to this animal, not the moose (*Alces alces*).

What it is

Elk are large mammals in the deer family, Cervidae. Males are bulls, females are cows, and young are calves. They are sexually dimorphic: bulls are bigger and grow antlers each year, while cows lack antlers. An adult bull can exceed 300 kg and stand 1.5 m at the shoulder.

Why it matters

Elk are a familiar wild species across western Canada, especially in the Rocky Mountains. They are herbivores that help shape ecosystems by grazing and browsing on grasses, shrubs, and leaves. The Canadian usage of “elk” specifically refers to *Cervus canadensis*, avoiding confusion with the moose, a different species.

Key details

Elk live about 10 to 15 years in the wild and inhabit forests, grasslands, shrublands, and mountain valleys. They are most active at dawn and dusk and often form herds. Their native range in Canada includes western provinces, though they are also found in parts of Asia.

In short

  • Elk are large deer, distinct from moose in Canadian usage.
  • Herbivores that graze and browse on a variety of plants.
  • Bulls grow antlers annually; cows do not.
  • Live 10–15 years in the wild, often in herds.
Canadian angle

Elk are a familiar wild species in Canada, especially in the Rocky Mountains and western provinces, and the Canadian usage of “elk” refers to *Cervus canadensis* rather than moose.
