Bison & Calf (Bison bison)

Yellowstone National Park, WY

Bison refers to the North American species as opposed to Bovids in other parts of the world, which are called buffalo. Bison are related to domestic cattle, sheep and goats. Bison stand 5 1/2 feet high at shoulders. Adult males (bulls) weigh 1200-2000 pounds while females (cows) weigh 700-900 pounds.

They breed in late summer and early fall. After a gestation period of 9 months, cows will usually have one calf, on occasion twins. Calves are weaned in the spring as yearlings. The bison feeds almost entirely on grasses and sedges.
