Largest Bighorn Boss Courts Ewe During the Rut

Largest Bighorn Boss Travels 40km to Court more Ewes During the Bighorn Sheep Rut. During this time, male bighorn sheep engage in various behaviors to establish dominance and compete for access to females, known as ewes. Dominant rams actively pursue ewes during the rut. They will try to gather a group of females, called a harem, and guard them from other males. Ewes may resist initially, and the pursuit can involve chasing and herding behaviors. Once a ram successfully establishes dominance and attracts a group of ewes, mating rituals take place. Bighorn Rams may engage in courtship displays, including lowering their heads, sniffing the females, and nuzzling them to encourage mating. The ultimate goal for the rams during the rut is to mate with as many ewes as possible to ensure reproductive success. The strongest and most dominant rams typically have better access to females and, therefore, a higher chance of passing on their genes. The Bighorn Sheep Rut is a crucial period as it plays a vital role in the continuation of the Bighorn species. This natural behavior shows the adaptations and strategies that have evolved to ensure successful Bighorn Sheep reproduction in challenging environments.

Bighorn Sheep Rut Season

When is the Bighorn Sheep Rut Season?

The Bighorn sheep rutting season or breeding season in Canada and the American Rockies is from October to January. During the bighorn rut, Rams fight for dominance by clashing heads in very physical battles. Each group of Bighorn Sheep will have a dominance order, with high ranking Rams(males) doing most of the breeding. Like Elk bulls after their rutting season, energy expended leaves bighorn rams in poor winter condition, resulting in a higher mortality rates among dominant rams.

During the bighorn rut, ram battles take place for the right to collect a harem of ewes(females). Bighorn Sheep Ram challenges can be a combination of show and bluff. When bluffing is matched, two rams will face each other, rearing up onto their hind legs, and smash their horns together with enourmous force. The battle sounds of these impacts are often compared to the reverberation of a high powered gunshot.

Dominant Bighorn Sheep Rams

Very large, dominant bighorn rams often have horns that make a full curl, continuing past they eye. It takes 7 or 8 years for Rams to reach this mature dominant stage and such animals are quite rare outside of protected areas.

Bighorn sheep ram horns can weigh up to 15 pounds on each side, meaning bighorn sheep males might have 30 pounds of horn on their head. Horns are rarely used for defense, but more for rutting season battles to establish breeding rights among the herd of ewes. Bighorn sheep ram fights are a wild animal experience not to be missed.
