The sambar (Rusa unicolor) is a large deer native to the Indian subcontinent, South China and Southeast Asia that is listed as a vulnerable species on the IUCN Red List since 2008. Populations have declined substantially due to severe hunting, local insurgency, and industrial exploitation of habitat. 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". Description The appearance and the size of the sambar vary widely across its range, which has led to considerable taxonomic confusion in the past; over 40 different scientific synonyms have been used for the species. In general, they attain a height of at the shoulder and may weigh as much as , though more typically . Head and body length varies from , with a tail. Individuals belonging to western subspecies tend to be larger than those from the east, and females are smaller than males. Among all living cervid species, only the moose and the elk can attain larger sizes. The large, rugged antlers are typically rusine, the brow tines being simple and the beams forked at the tip, so they have only three tines. The antlers are typically up to long in fully adult individuals. As with most deer, only the males have antlers. 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. The tail is relatively long for deer, and is generally black above with a whitish underside. Adult males and pregnant or lactating females possess an unusual hairless, blood-red spot located about halfway down the underside of their throats. This sometimes oozes a white liquid, and is apparently glandular in nature. Distribution and habitat The sambar is distributed in much of South Asia as far north as the south-facing slopes of the Himalayas in Nepal, Bhutan and India, in mainland Southeast Asia including Burma, Thailand, Indochina, the Malay Peninsula, Indonesia (Sumatra and Borneo), Taiwan, and South China, including Hainan. In the Himalayan foothills, Myanmar, Sri Lanka, and eastern Taiwan, it ranges up to . It inhabits tropical dry forests, tropical seasonal forests, subtropical mixed forests with stands of conifers and montane grasslands, broadleaved deciduous and broadleaved
