They do not actually fly but glide from tree to tree. They are similar in appearance to the northern flying squirrel, however, they are generally smaller and have darker pelage. They are good gliders but clumsy walkers on the ground.
Humboldt's flying squirrels are found in coniferous and mixed coniferous forests from southern British Columbia to southern California. They live in thick coastal forests where there is plenty of room for them to glide from tree to tree.
They feed on a variety of plant material as well as tree sap, fungi, insects, carrion, bird eggs and nestlings. They mostly breed once a year in a cavity lined with lichen or other soft material. Unlike most members of their family, flying squirrels are strictly nocturnal. They nest in the tops of the trees away from the ground and predators.
