Northern flying squirrels are nocturnal gliders, so New Hampshire’s 58 records lean heavily on GBIF specimen and trapping data (54 of 58) rather than photographs, since spotting one gliding between trees after dark is genuinely difficult. NatureServe rates the state population S5, secure, fitting a species tied to the boreal and mixed forest that covers much of the White Mountains and North Country.

Records peak in October (6) and again in July (5), with nothing at all recorded in January, a pattern more likely shaped by when researchers run live-trapping surveys than by any real seasonal shift in the squirrel’s own activity, since this species doesn’t hibernate and stays active through winter nights.
