Capra sibirica.

North goat (Capra sibirica), also known as hanging goat, wild goat, Asian antelope and so on, is the wild ancestor of goats.
North goat is a key protected wildlife at the national level. It is widely distributed in the alpine areas of Central Asia, in northern India, Afghanistan and Mongolia, and in Xinjiang, northwest Gansu and northwest Inner Mongolia in China. Habitat in the altitude of 3500-6000 meters plateau bare rock, steep cliffs and rugged hillside terrain, winter does not migrate to very low places, so it can be called one of the highest habitat mammals. North goats are very good at climbing and jumping. Their hooves are very solid. They have elastic heel joints and pliers like toes. They usually cluster in the morning and evening and eat all kinds of weeds.
North goat is a typical sex-type species (i.e. the size of adult male and female individuals is obviously different). The weight of adult male goats is about twice that of female goats, and there are obvious differences in the shape and size of the horns (adult male horns are sickle-shaped). Therefore, we can clearly distinguish adult females (small horns, long horns) according to the length of the horns and the "cross ridges" on the horns of North goats. Only 19-39 cm with no "transverse ridge" on the horn and adult males (strong horn, angle length up to 100-148 cm and obvious "transverse ridge" on the horn). The "cross ridge" can also be used to estimate the age of male goats. In most years, the horns of male goats grow two "cross ridges" each year, so dividing the number of "cross ridges" by two plus one year old is the age of male northern goats.
North goats are also a typical homosexual cluster species. Like humans, most boys/girls prefer to play with boys/girls if not for love.
