Habitat
This species primarily inhabits montane forests on the island of Sulawesi, Indonesia, at elevations between 1,000 and 2,500 meters. It prefers dense, tropical rainforests with abundant trees for cover and food, avoiding lower altitude or disturbed areas.
Diet
The Montane long-nosed Squirrel feeds mainly on fruits, seeds, and nuts gathered from the forest canopy. It also consumes insects and occasionally small invertebrates or bird eggs. Feeding activity peaks during the early morning and late afternoon when it forages alone or in small groups.
Behavior
These squirrels are diurnal and arboreal, spending most of their time climbing and leaping between trees in search of food. They are generally solitary but may interact during mating season, exhibiting territorial behavior by marking trees with scent glands. Notable behaviors include quick escapes into foliage when threatened and caching food for later use.
Conservation Status
The IUCN lists Hyosciurus heinrichi as Vulnerable due to ongoing habitat loss from deforestation and agriculture. Population trends are decreasing, with major threats including logging and human settlement in their montane habitats.
