![]() Male mountain goats are typically larger, stronger, and heavier than females and have a longer beard than the females. Male goats also have longer horns and longer beards than females. Their coats help them to withstand winter temperatures as low as −46 ☌ (−51 ☏) and winds of up to 160 kilometres per hour (99 mph).Ī male goat stands about 1 m (3.3 ft) at the shoulder to the waist and can weigh considerably more than the female (around 30% more in some cases). Mountain goats molt in spring by rubbing against rocks and trees, with the adult billies shedding their extra wool first and the pregnant nannies shedding last. The fine, dense wool of their undercoats is covered by an outer layer of longer, hollow hairs. ![]() They are protected from the elements by their woolly greyish white double coats. General appearance and characteristics Mountain goat on Mount Massive, Colorado, United Statesīoth male and female mountain goats have beards, short tails, and long black horns, 15–28 cm (5.9–11 in) in length, which contain yearly growth rings. The name Oreamnos is derived from the Greek term ὄρος óros (stem ore-) meaning "mountain" (or, alternatively, oreas "mountain nymph") and the word ἀμνός amnós meaning "lamb". The mountain goat is the only living species in the genus Oreamnos. Ancient DNA studies suggest that this was the sister species of the living mountain goat, not its ancestor consequently, the living species would also date back to the Pleistocene at least. In the Pleistocene era, the small prehistoric mountain goat Oreamnos harringtoni lived in the southern Rocky Mountains. No Pliocene mountain goats have been identified yet the known fossil record is fairly recent, entirely from North America, and barely differs from the living animals. The mountain goat's ancestors thus probably crossed the Bering Strait after they split from their relatives, presumably before the Wisconsinian glaciation. Given that all major caprine lineages emerged in the Late Miocene and contain at least one but usually several species from the eastern Himalayan region, their most likely place of origin is between today's Tibet and Mongolia or nearby. The mountain goats probably diverged from their relatives in the late Tortonian, some 7.5 to 8 million years ago. The sheep lineage is also very closely related, while the muskox lineage is somewhat more distant. Other members of this group are the bharal, the true goats, and the Himalayan tahr. The takins of the Himalayan region, while not a sister lineage of the mountain goat, are nonetheless very closely related and almost coeval to the mountain goat they evolved in parallel from an ancestral goat. It belongs to the subfamily Caprinae, along with true goats, wild sheep, the chamois, the muskox and other species. The mountain goat is an even-toed ungulate of the order Artiodactyla and the family Bovidae (along with antelopes, gazelles, and cattle). Mountain goats generally avoid venturing down into lower elevations-except during seasonal food shortages or during particularly bad weather-as the extreme elevation which they inhabit is their primary defense against predators such as black and brown bears, pumas and wolves.ĭespite its vernacular name and both genera being in the same subfamily ( Caprinae), the mountain goat is not a member of Capra, the genus that includes all other goats (such as the wild goat ( Capra aegagrus), from which the domestic goat is derived) rather, it is more closely allied with the other bovids known as “ goat-antelopes”, including the European chamois ( Rupicapra), the gorals ( Naemorhedus), the takins ( Budorcas) and the serows ( Capricornis), of Japan and eastern South Asia. A subalpine to truly alpine species, it is a sure-footed climber commonly seen on sheer rock faces, near-vertical cliffs and icy passages. The mountain goat ( Oreamnos americanus), also known as the Rocky Mountain goat, is a cloven-footed mammal that is endemic to the remote and rugged mountainous areas of western North America.
