Glaucomys sabrinus
A large North American flying squirrel of northern conifer forest, with silky grey and cinnamon fur and belly hairs that are grey at the base. Strictly nocturnal, it glides between trees and eats many fungi and lichens.
The northern flying squirrel (Glaucomys sabrinus) is a gliding squirrel ranging across northern North America from Alaska to Nova Scotia, south to the mountains of North Carolina and Tennessee and west to Utah. It prefers spruce and fir forest but also lives in deciduous and mixed woods. The silky fur is grey and cinnamon, and a furred gliding membrane runs from wrist to ankle. The flat, round-tipped tail is about 80% of head-and-body length, and the large black eyes suit night activity. It is told from the southern flying squirrel (G. volans) already kept in Japan by its larger size and belly hairs that are grey at the base (often white to the base in the southern species). It is strictly nocturnal, active for about two hours starting an hour after sunset and again before dawn. Clumsy on the ground, it glides gracefully between trees, and up to eight may share a nest. Besides nuts and acorns, fungi and lichens form a large part of its diet. Most wild animals live less than four years; the captive average is 13. In Japan, captive-bred animals appear only occasionally at specialists.

Nomenclature follows global taxonomic authority databases.
Not covered by CITES or the specified-animal rules. As a member of the squirrel family, it needs a species-name certificate under the Invasive Alien Species Act when imported (it is not itself a designated or uncategorized invasive species). Imports fall under Japan's animal import notification system (Infectious Diseases Control Law, MHLW): a health certificate from the exporting country's government must be filed with the quarantine station, and rodents must come from a holding facility designated by that government. Animals bred in Japan can be sold and kept without notification. Never release captive animals into the wild.

Omnivore: nuts, acorns, fungi and lichens, plus fruit and insects
It travels by gliding between trees. Provide a tall, deep cage with high nest boxes and branches, and make the room safe before letting it out.
Unlike most squirrels, fungi and lichens are a major part of its diet alongside nuts and acorns; it also takes fruit, buds, sap, insects and eggs.
Strictly nocturnal, active after sunset and before dawn. Up to eight may share a nest, and same-sex groups huddle for warmth in winter.
A species of cold northern conifer forest with little data on heat tolerance; air-condition the room through a Japanese summer.
As a squirrel it needs a species-name certificate on import, and imports fall under the animal import notification system.
Larger than the southern flying squirrel (G. volans), with grey-based belly hairs; captives can live over 10 years. Never release captive animals into the wild.
