Hippocamelus is a genus of Cervidae, the deer family. It comprises two extant Andean and two fossil species. The living members are commonly known as the huemul (from the Mapuche language), and the taruca, also known as northern huemul.
Both species have a stocky, thick, and short-legged body. They live at high altitudes in the summer. Though Taruca spends their whole life cycle at these high altitudes, especially as populations get nearer the Ecuator line, Southern Huemul, moves down the mountains in the fall and spend the winter in sheltered forested valleys.
Areas with fresh water are preferred. They are herbivores that feed primarily on herbaceous plants and shrubs as well as sedges, lichens, and grasses found between the rocks on high peaks. They are active during daytime and have a lifespan of about ten years.[citation needed]
The huemul (Hippocamelus bisulcus), also known as the South Andean deer, is found in Chile and Argentina. Huemuls live in groups of varying size, typically of two or three individuals, but sometimes as many as eleven. In the past, groups of over a hundred deer were reported.[citation needed] Groups are made up of a female and her young, while males are often alone.
Huemul occur in several national parks in Chile and neighbouring parts of Argentina and have been on the Endangered list since 1996. They are endangered primarily due to human impacts such as deforestation, habitat fragmentation by roads, introduction of non-native mammals such as farm animals, and poaching. They are in a classic "extinction spiral" marked by increasingly small, isolated populations.[citation needed]
The taruca (Hippocamelus antisensis), also called Northern Huemul, is mainly found in Peru. Scattered potpulations are also found in high mountain regions of Bolivia, and in a less extent in northern Chile and Argentina, inhabiting treeless Puna grasslands. They live at high altitudes ranging from 3,500 to 5,200 meters above sea level.
