Northern flying squirrel holds a solid 169-record showing in Idaho, though its record actually centers on the state’s forested mountains rather than the river-valley refuges listed here. As a strictly nocturnal glider, the species is almost never seen in daylight, so nearly all of this documentation comes from nest-box surveys and trapping.
Records spike to 50 in January, an unusual winter peak that likely reflects a concentrated trapping or nest-box survey rather than true winter activity, before settling into a more typical May-through-August pattern. NatureServe ranks the species S4, Apparently Secure, in Idaho.
