Habitat
This species is endemic to Siau Island in Indonesia, primarily inhabiting tropical rainforests and secondary growth areas with dense vegetation. They prefer elevations up to 700 meters, where they can find ample tree cover for arboreal living.
Diet
The Siau Island tarsier mainly feeds on insects such as beetles, moths, and crickets, which it catches using its agile leaps and sharp hearing. It hunts nocturnally, often perching quietly before pouncing on prey. Feeding activity peaks during the early night hours.
Behavior
Siau Island tarsiers are nocturnal and arboreal, spending their nights leaping between trees in search of food while being solitary or forming loose pairs. They exhibit territorial behavior by marking areas with scent and vocalizations, and they are known for their ultrasonic calls to communicate. These tarsiers are generally shy and avoid human contact, relying on camouflage and quick movements to evade threats.
Conservation Status
The IUCN status of the Siau Island tarsier is Critically Endangered, with a declining population due to habitat loss from deforestation and predation by introduced species. Major threats include volcanic activity on Siau Island and human encroachment.
