Hippocamelus is a
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

Huemul
The
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 huemul is, along with the
Taruca
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.
Social habits include grazing in flexible groups of up to thirty animals consisting of one or two males and several females.[1]
Taxonomy and evolution
In 2008, a genetic study indicated that the huemul and taruca may not be closely related, and that the taruca should therefore be placed in a separate genus.[2] This has been contradicted by more recent studies.[3]
Fossils belonging to the now extinct species Hippocamelus sulcatus have been identified from Brazil, Uruguay, and Argentina. This species inhabited lowland plains habitats, rather than mountains, and lived between 1.5 and 0.5 million years ago, during the mid to late Pleistocene. Its exact relationship to the living species is unclear. A second fossil species, Hippocamelus percultus, is known from the Bolivian Andes, and lived around 40,000 to 20,000 years ago; it may be a direct ancestor of the living taruca.[4]
