Male Timorensis Deer are larger than females. Both have a rough grayish-brown coat that is often coarse in appearance. Their ears are rounded and broad and the animals look short and stubby because of their short legs. Timorensis Deer live between 15 to 20 years in the wild and in captivity. They are herbivorous and mainly feed on grass, leaves, and fallen fruits.
Timorensis Deer are polygynous which means that males mate with more than one female during each breeding season. During the mating season, males decorated their antlers with grass and twigs to attract females and intimidate competitors. Male become very vocal and contest by calling in a loud, shrill bark and dueling with antlers. Females give birth to one or two fawns after a gestation period of 8 months and young fawn stay mothers until they reach sexual maturity at 3 to 5 years old.
Unfortunately, Timorensis Deer are threatened by habitat destruction, illegal hunting, and by the expansion of agriculture. These deer are poached with guns, snares, and dogs and usually hunted in their native range for meat, medicinal products, handicraft products, and pets. Apart from that, Timorensis Deer plays an ecosystem role in dispersing seeds in the forest.
