PictureWestern Tarsier (Tarsius bancanus)


Family: TARSIIDAE

Tarsiers are small, long-tailed primates which jump from tree to tree and feed exclusively on small animals. The distribution of the family, which contains only the genus Tarsius, is restricted and unusual: in addition to the Western Tarsier, T. bancanus, two other species are recognised, one in Sulawesi and offshore islands, the other in Mindanao, Bohol, Leyte and Samar in the southern Philippines.

Measurements:
HB 121-154, T 181-224, HF 59-71 (12 specimens). Wt 86-135 kg.

Identification:
General coloration varies from pale olive-or reddish-brown to pale or dark grey-brown (possible varying with age). Fur soft. Tail hairless except at the end. Digits slender with large terminal pads and pointed nails, except for second and third toes on hind feet, which bear a large claw. The eyes, although large, do not reflect torchlight.

Ecology & habitat:
Nocturnal. Active from ground level up to at least 7 m, often leaping between vertical supports at lower levels. Diet mainly large insects. Apparently forages for food singly, making high-pitched calls frequently. Found in a variety of tall and secondary forests.

Distribution:
Borneo - Tarsius bancanus borneanus known from many lowland sites in Sabah, Brunei, Sarawak and West Kalimantan, and above 900 m in the Kelabit uplands in northern Sarawak. Elsewhere, recorded only from Kutai and Peleben in East Kalimantan and Tumbang Maruwe in Central Kalimantan.
