BIGHORN SHEEP FACTS

distribution map showing range of Ovis canadensis in North America
Description
The Bighorn Sheep has brown coat in summer that becomes faded by winter. The male has large broad horns that can weigh up to 14kg. The female has much smaller horns. They are found in small groups, and can form herds of up to 100 animals. They are adept climbers and can scramble up mountain slopes with ease. They are also good swimmers.

Size
length: males 1.6-1.8m; females are smaller growing to 1.5m

Environment
alpine meadows, grassy mountain slopes, mountain foothills near rocky cliffs and bluffs. Bighorn sheep live where annual snowfall is less than about 150cm a year as they cannot paw through deep snow to feed

Food
grasses, sedges, herbaceous plants

Breeding
A single young (rarely two) is born after gestation of 150-180 days. The young is weaned after 4-6 months.

Notes
Bighorn rams battle each other in head-to-head combat, and these battles can go on for hours until one male concedes. They have double-layered skulls with struts of bone joining the layers to protect their heads in battle.
