Northern flying squirrels are nocturnal gliders and genuinely hard to spot after dark, yet all 12 of New Hampshire’s records are iNaturalist observations, with Coos and Sullivan counties logging three each. 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.

July has the most records, 5, and nothing turns up from January through April or September through November, but 12 records are too few to show a real season, especially for a squirrel that doesn’t hibernate and stays active through winter nights.
