Japanese Dwarf Flying Squirrels At Dusk | Pteromys volans orii

Pictured here is a pair of a Japanese dwarf flying squirrel (Pteromys volans orii), one peeking out from the nest, and another perched on a branch above. These squirrels are preparing for a night of foraging, having emerged shortly after sunset. Known locally as ezo-momonga, this sub-species is a sub-species of Siberian flying squirrel and is found only in Hokkaido, Japan. It is primarily nocturnal. Mature females measure up to 15cm, males up to 18cm (not including tail). These animals weigh up to 120g and are capable of gliding considerable distances. During flight, they use their patagia (membranes of skin between their forelimbs and hind limbs) and tails (10-12cm) to achieve lift, directional control and maneuvering capability. One study in Japan recorded a maximum glide distance exceeding 49m, though most flights fell into the 10m to 20m range.
