Bighorn sheep live in large herds and do not typically follow a single leader ram, unlike the mouflon, the ancestor of the domestic sheep, which has a strict dominance hierarchy. Before the mating season or " rut ", the rams attempt to establish a dominance hierarchy to determine access to ewes for mating.

The domestic sheep (Ovis aries) is the only species of mammal except for humans which exhibits exclusive homosexual behavior.
