The bighorn sheep technical name is Ovis Canadensis. The horns of a male bighorn can weigh up to 30 lbs (13.5 kg)more than all the bones
in his body combined. Females (ewes) also have horns, but they are of smaller size. Desert Bighorns don't need to drink water in the winter
because the plants they eat provide enough liquid for them. In the summer they have to drink water about once in three days.
two male bighorn sheep, when they run towards each other for attacking, acquire a speed equal to nearly 15 miles per hour! Moreover,
the clashes of their sound echoes in the mountains. Male bighorn sheep have large horn cores, enlarged cornual and frontal sinuses and internal bony septa. These adaptations serve to protect the brain by absorbing the impact of clashes.
Bighorn sheep live in large flocks, and do not typically follow a single leader ram, unlike the mouflon, the ancestor of the domestic sheep, which has a strict dominance hierarchy. Prior to the mating season or "rut", the rams attempt to establish a dominance hierarchy that determines access to ewes for mating. It is during the prerut period that most of the characteristic horn clashing occurs between rams, although this behavior may occur to a limited extent throughout the year. Ram's horns can frequently exhibit damage from repeated clashes.
