Argalis are highly gregarious animals, found in large single-sex herds that may number up to 100 individuals (2). During the mating season, these herds come together and males will compete for access to the receptive females (2). These are often violent and the clashing of horns can be heard reverberating around the mountains (2). Around 5 months later, females give birth to a litter of 1 or 2 lambs; they separate from the main herd in order to give birth and the newborns remain hidden in the grass whilst their mother feeds (2).  These sheep graze on grasses, herbs and sedges; herds may migrate to higher elevations during the summer months in search of fresh pasture (2).
