Sambar

Rusa unicolor

Vulnerable

At high risk of extinction in the wild over the medium term.

Spotted something wrong?

The sambar is the largest deer in tropical Asia and the tiger's preferred prey over much of its range. It is robust, with a dark brown, coarse coat, a neck mane more pronounced in males and antlers with only three tines each. It is largely nocturnal and fairly solitary. It likes water: it wallows in mud and enters rivers and lagoons to eat aquatic plants. Its population has fallen by more than 50% in three generations through hunting and forest loss.

Fun facts

  • GeneralThe largest deer in tropical Asia; heavily dependent on water, it often takes to the water to swim.
  • comunicaciónIt is one of the largest deer in Asia, and its alarm call — a loud bark — is used by other forest animals as an indirect warning that a tiger is about.
  • It is the tiger's preferred prey wherever the two occur together: a single adult sambar feeds a tiger for several days, and sambar abundance is one of the best predictors of tiger density in a reserve.
  • When it detects a predator it gives a powerful alarm snort and stamps its feet, a signal that guides in India use to locate tigers and leopards.

The sambar is classified as vulnerable. Organisations such as the IUCN, WWF and the Wildlife Conservation Society work specifically on its conservation and that of its habitat; looking into their programmes is a good starting point if you want to get involved.

It's documented in 10 protected areas — one reason why protecting these places matters for its conservation.
