The sambar (Rusa unicolor) is a large deer native to the Indian subcontinent, southern China, and Southeast Asia that is listed as vulnerable on the IUCN Red List since 2008.
The name “sambar” is also sometimes used to refer to the Philippine deer, called the “Philippine sambar” and the Javan rusa, called the “Sunda sambar“.
The shaggy coat can be from yellowish brown to dark grey in colour, and while & it is usually uniform in colour, some subspecies have chestnut marks on the rump and underparts. Sambar also have a small but dense mane, which tends to be more prominent in males.
Adult males and pregnant or lactating females possess an unusual hairless, blood-red spot located about halfway down the underside of their throats.
The sambar is distributed in much of South Asia as far north as the south-facing slopes of the Himalayas in Nepal and India, in mainland Southeast Asia including Burma, Thailand, Indochina, the Malay Peninsula, South China including Hainan Island, Taiwan, and the Indonesian islands of Sumatra and Borneo. In the Himalayan foothills, Myanmar, and eastern Taiwan, it ranges up to 3,500 m (11,500 ft).
Sambar feed on a wide variety of vegetation, including grasses, foliage, browse, fruit, and water plants, depending on the local habitat.
