Habitat
Horsfield's tarsier primarily inhabits dense lowland and hill forests in Southeast Asia, including parts of Malaysia, Indonesia, and Borneo. They prefer areas with thick vegetation for cover and hunting, avoiding open spaces and higher elevations above 1,000 meters.
Diet
Horsfield's tarsier mainly feeds on insects such as beetles, crickets, and moths, which it catches by leaping and pouncing at night. They hunt using their acute hearing and vision in the dark, often consuming their prey whole. Feeding primarily occurs during the nocturnal hours, with individuals spending several hours each night foraging.
Behavior
Horsfield's tarsier is nocturnal and primarily solitary, though pairs or family groups may share territories. They are highly territorial, marking areas with scent and communicating via ultrasonic calls inaudible to humans. Notable behaviors include vertical clinging and leaping between trees, as well as freezing in place when threatened to avoid detection.
Conservation Status
Horsfield's tarsier is classified as Vulnerable by the IUCN due to habitat loss from deforestation and fragmentation. Population trends are declining, with major threats including agricultural expansion and hunting for the pet trade.
