Diet
Bighorn are primarily grazers, feeding in meadows, open woodland, and alpine tundra. However, they will also eat forbs (herbaceous plants) in the summer and browse in the winter. Grasses eaten by bighorn include bluegrass, sedges, wheat grass, bromes and fescues. Browse includes willow, mountain mahogany, winterfat and bitter brush. Forbs include clover, cinquefoil and phlox.
