Bighorn sheep, with huge horns and a robust body, are native to North America and have seven different subspecies, five of which live in desert areas. And in mountainous areas, bighorn sheep live in remote and barren mountains and ridges. Mountain bighorn sheep are the largest and most numerous among these 7 species. Mountain bighorn sheep are more agile than goats, and rams are also better at fighting than other types of rams. During the mating season, the sound of them colliding head-on always echoes in the mountains. Males have spiral shaped large horns, while females have missing or short horns. The main food source is the tender branches and leaves of grass and shrubs. Visual acuity, able to detect the approaching danger in the distance and issue warnings to the group.
