Habitat
Humboldt's flying squirrels primarily inhabit coniferous and mixed evergreen forests in the Pacific Northwest, from southwestern British Columbia through Washington, Oregon, and northern California. They prefer old-growth forests with large trees for nesting and gliding, often at elevations from sea level up to 2,500 meters. These areas provide ample canopy cover and proximity to water sources.
Diet
Their diet consists mainly of nuts, seeds, and fungi, such as acorns, pine seeds, and truffles, which they forage at night. They also eat berries, insects, and occasionally bird eggs or nestlings to supplement their nutrition. Feeding occurs primarily in the canopy, where they use their gliding ability to access food sources efficiently.
Behavior
Humboldt's flying squirrels are nocturnal and arboreal, spending most of their time in trees and gliding between them to escape predators or find food. They are generally solitary but may share dens in winter for warmth, and they exhibit territorial behavior by marking trees with scent. Notable behaviors include caching food for later use and communicating with high-pitched calls.
Conservation Status
The IUCN status for Humboldt's flying squirrel is Least Concern, with a stable population trend, though habitat loss from logging poses a threat in some areas.
