The mammals are the class of vertebrate animals characterized by the presence of mammary glands, the presence of hair or fur; specialized teeth; the presence of a neocortex region in the brain; and endothermic or 'warm-blooded' bodies. The brain regulates endothermic and circulatory system, including a four-chambered heart. In India there are 410 species, 186 genera, 45 families and 13 orders of which nearly 89 species are listed as threatened in the International Union for Conservation of Nature and Natural Resources (IUCN) Red List of Threatened Animals (IUCN 2006).

The Siberian ibex (Capra sibirica) is seen in central Asia and Western Himalayas in India. They are large and heavily built goats. Usually living at high elevations, sometimes at the vegetation line and well above the tree line, Siberian ibexes seek out lower slopes during the winter in search of food. They have also been known to seek out tree lines on hot days, but they do not enter forested areas, preferring to return to their alpine habitat when the weather has cooled. When snow is heavy, they have to paw away snow to reach the vegetation below.
