Northern flying squirrels are nocturnal gliders, so Vermont’s 36 records lean toward GBIF specimen and trapping data (34 of 36) rather than photographs, since spotting one gliding between trees after dark is genuinely difficult. NatureServe rates the state population S4, apparently secure, fitting a species tied to the mixed and coniferous forest that spans the Green Mountains and Champlain Valley uplands.

Records go completely silent in July and August, then rebound to a September peak of 7, a pattern more likely shaped by when researchers run live-trapping surveys, since this species doesn’t hibernate and actually stays active through the summer nights the record shows nothing for.
