Bighorn Sheep (Ovis canadensis)[1] are one of two species of mountain sheep in North America; the other species being Ovis dalli, that includes Dall Sheep and Stone's Sheep. The taxononomy continues to be modified as new genetic and morphologic data becomes available but most scientists currently recognize the following subspecies of bighorn:[2][3]

Rocky Mountain Bighorn Sheep (Ovis canadensis canadensis)
Sierra Nevada Bighorn Sheep (Ovis canadensis sierrae), formerly California Bighorn Sheep, [3]
Desert Bighorn Sheep (Ovis canadensis nelsoni)
In addition, there are currently 2 federally endangered populations:[4]

Sierra Nevada Bighorn Sheep (Ovis canadensis sierrae), recognized as a unique subspecies
Peninsular Bighorn Sheep, a distinct population segment of Desert Bighorn Sheep (Ovis canadensis nelsoni)

Bighorn Sheep are named for the large, curved horns borne by the males, or rams. Females, or ewes, also have horns, but they are short with only a slight curvature. They range in color from light brown to grayish or dark, chocolate brown, with a white rump and lining on the back of all four legs. Rocky Mountains bighorn females weigh up to 200 pounds (90 kg), and males occasionally exceed 300 pounds (135 kg). In contrast, Sierra Nevada bighorn females weigh about 140 pounds (63 kg) with males weighing around 200 pounds (90 kg). Males horns can weigh up to 30 lbs (14 kg), as much as the rest of the bones in the male's body.[8]

Bighorn sheep graze on grasses and browse shrubby plants, particularly in fall and winter, and seek minerals at natural salt licks. Bighorns are well adapted to climbing steep terrain where they seek cover from predators such as coyotes, eagles, and cougars. They live in large herds, but because they do not have the strict dominance hierarchy of the mouflon, they cannot be domesticated. This is because bighorns do not automatically follow a single leader ram as the Asiatic ancestors of the domestic sheep did and do.

Bighorn Sheep in Alberta, Canada.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.[9] Ram's horns can weigh more than 40 pounds (18 kg), and frequently exhibit damage from repeated clashes. Bighorn ewes exhibit a 6 month gestation. In temperate climates, the peak of the rut occurs in November with 1, or rarely 2, lambs being born in May. They are then weaned for 4-6 months.

Bighorn sheep are highly susceptible to certain diseases carried by domestic sheep such as scabies and pneumonia; additional mortality occurs as a result of accidents involving rock fall or falling off cliffs (a hazard of living in steep, rugged terrain).

Hi Rick,

A great action scene. You really have a diversified portfolio. The details are wonderful and I love the neutral colors. They seem to be enjoying their head butting.


Hello Rick
Excellent shot of these Bighorn Sheeps,
Perfect compo and lighting,
Great POV, Welldone.


This is a great capture Rick. I suspect that these two are still a bit young to win a harem but I bet it was fun to see them doing what comes naturally. I thing the image could use a little brightening up... but that could just be the difference between viewing on a PC and a Mac. I did a workshop but it may look dark if you are a PC user. It looked good on my Mac.

Hi Rick,
great action you captured here with those two fighters. Very nice timing just as the make contact.. goodsharpness and nice colors in this composition.

Great image again...Rick!
Impressive wildlife shot at a decisive moment...

Hello Rick,
Some friendly action has been well captured!
Great details in the animals, who still are in the process of getting rid of the winter coats...
I like the composition, and the early summer colours are still dominant!
