Northern flying squirrels are nocturnal gliders, and Vermont has just 18 records of the species since 2000, all of them iNaturalist observations, a thin count for an animal that’s genuinely hard to spot gliding between trees after dark. 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 silent in July and August and pick up again in September and October, with April the single busiest month, though with only 18 records those swings come down to a few sightings either way. This species doesn’t hibernate and stays active through the summer nights the record shows nothing for, so the gap says more about who’s out looking than about the squirrels.
