The Sambar Deer is currently classified as a vulnerable species on the IUCN Red List. Over the past three decades, their population has declined by more than 50% in Southeast Asia, Borneo, and Sumatra. The main threats to their existence include habitat loss, rampant poaching, and the high demand for their meat and antlers.
Conservation efforts are underway to protect the habitats of Sambar Deer and regulate hunting practices to ensure the survival of this iconic species for future generations.
Sambar Deer Behavior and Predators
Sambar Deer are primarily nocturnal and crepuscular, being most active at dawn and dusk. Males lead a solitary life, while females live in small herds. They often congregate near water sources and are good swimmers.
Sambar Deer are known for their unique behaviors, such as marking their territories by rubbing their antlers on trees and standing on their hind legs to clash their antlers during courtship. They communicate through scent marking, foot stamping, alarm barks, and vocalizations.
Sambar Deer have a wide variety of vegetation in their diet, including grasses, foliage, browse, fruits, and water plants. They are an important prey species for predators such as tigers, Asiatic lions, leopards, and dholes (wild dogs). Tigers, in particular, prey on Sambar Deer and can comprise up to nearly 45% of their biomass consumed by Bengal tigers in India.
Sambar Deer are known to defend their young from predators, exhibiting defensive behaviors like lowering their heads, erecting their manes, and vocalizing loudly to discourage predators.
