The northern flying squirrel (Glaucomys sabrinus) is one of three species of the genus Glaucomys, the only flying squirrels found in North America. [2] [3] They are found in coniferous and mixed coniferous forests across much of Canada, from Alaska to Nova Scotia, and south to the mountains of North Carolina and west to Utah in the United States.
A northern flying squirrel (Glaucomys sabrinus) gliding. Flying squirrels are not capable of flight like birds or bats; instead, they glide between trees. They are capable of obtaining lift within the course of these flights, with flights recorded to 90 metres (300 ft).
Predators of these flying squirrels include raccoons, Pacific martens, and probably barred owls. The raccoon population on the island is small, and therefore most likely does not have a large impact on the flying squirrel population. Studies have shown that flying squirrels only make up about 5-7% of a marten's diet.
Gray squirrels are active during the day, while flying squirrels are active at night, says Mengak. If you discover a squirrel nesting in your home or shed, look for its entryway into the structure ...

Using genetic analyses, Arbogast et al. (2017) [2] showed that Humboldt's flying squirrel, previously thought to be conspecific with the northern flying squirrel, was actually a distinct species. The San Bernardino flying squirrel subspecies (G. o. californicus) is considered a Critically Imperiled Subspecies by NatureServe. [3]
Sciurinae (/ s ɪ ˈ j uː r ɪ n eɪ /) is a subfamily of squirrels (in the family Sciuridae), uniting the flying squirrels with certain related tree squirrels. Older sources [1] [2] place the flying squirrels in a separate subfamily (Pteromyinae) and unite all remaining sciurids into the subfamily Sciurinae, but this has been strongly refuted by genetic studies.
