The bighorn sheep (Ovis canadensis) [6] is a species of sheep native to North America. [7] It is named for its large horns.A pair of horns may weigh up to 14 kg (30 lb); [8] the sheep typically weigh up to 143 kg (315 lb). [9]
Desert bighorn sheep populations have trended upward since the 1960s. The upward trend was caused by conservation measures, including habitat preservation. In 1978, desert bighorn sheep populations were estimated at 8,415-9,040. [15] A state-by-state survey published in 1985 estimated the overall US desert bighorn sheep population at 15,980. [16]
The Sierra Nevada bighorn sheep (Ovis canadensis sierrae) is subspecies of bighorn sheep unique to the Sierra Nevada mountains of California. [3] A 2016 genetics study confirmed significant divergence between the three subspecies of North America's bighorn sheep: Sierra Nevada bighorn sheep, Rocky Mountain bighorn sheep and desert bighorn sheep.

Bighorn sheep get their name from the large horns atop their head, which curve backwards toward the sheep's body. They can weigh between 140-300 pounds and average about 3–3½ feet tall ...
There are only approximately 80,000 North American bighorn sheep on the continent currently — much less than the between 150,000 and 200,000 that existed before the 1800’s.
This is a collection of lists of mammal gestation period estimated by experts in their fields. The mammals included are only viviparous (marsupials and placentals) as some mammals, which are monotremes (including platypuses and echidnas) lay their eggs. A marsupial has a short gestation period, typically shorter than placental.
Domesticated sheep are herd animals that are bred for agricultural trade. A flock of sheep is mated by a single ram, which has either been chosen by a farmer or, in feral populations, has established dominance through physical contests with other rams. [1] Sheep have a breeding season (tupping) in the autumn, though some can breed year-round. [1]
The Badlands bighorn (Ovis canadensis auduboni), commonly known as Audubon's bighorn sheep, is an extinct subspecies or population of bighorn sheep of the northern Great Plains in North America. Its existence as a separate subspecies is disputed.
