Habitat
Hagen's flying squirrel primarily inhabits lowland and montane rainforests in Borneo, preferring areas with dense canopy cover for gliding. They are found at elevations up to 1,500 meters, often in old-growth forests with plenty of trees for nesting and foraging. These habitats provide the necessary vertical space for their arboreal lifestyle.
Diet
Hagen's flying squirrel feeds mainly on fruits, nuts, and seeds from trees like figs and dipterocarps, supplemented by insects and occasionally bird eggs. They forage at night, using their gliding ability to move between trees and access food sources efficiently. Feeding behavior includes caching food in tree hollows for later use.
Behavior
Hagen's flying squirrel is nocturnal and arboreal, spending most of its time in trees and gliding between them to escape predators or find food. They are generally solitary, except during mating season, and maintain small territories in the forest canopy. Notable behaviors include building nests in tree hollows and emitting high-pitched calls for communication.
Conservation Status
Hagen's flying squirrel is classified as Vulnerable by the IUCN due to habitat loss from deforestation and logging. Population trends are declining, with major threats including fragmentation of rainforest habitats and human encroachment.
