Habitat
This species primarily inhabits tropical rainforests on the Mentawai Islands off the coast of Sumatra, Indonesia, favoring dense canopies and old-growth forests for gliding and nesting. It prefers elevations from sea level up to about 500 meters, where there is ample tree cover and fruit-bearing vegetation.
Diet
The Mentawai flying squirrel feeds mainly on fruits, seeds, and insects, often foraging in the forest canopy at night. It supplements its diet with nectar and possibly young leaves, using its sharp incisors to access hard-shelled nuts and fruits.
Behavior
Mentawai flying squirrels are nocturnal and solitary, spending their nights gliding between trees in search of food and retreating to tree hollows or nests during the day. They are territorial, marking their ranges with scent and vocalizations, and use gliding to escape predators or cover distances up to 50 meters. Males may engage in brief interactions during mating season but otherwise avoid social contact.
Conservation Status
The IUCN lists the Mentawai flying squirrel as Vulnerable due to habitat loss from logging and agriculture, with populations declining rapidly. Major threats include fragmentation of rainforests and potential hunting by locals.
