Northern hoary bats carry a NatureServe S3 vulnerable rank in New Jersey that matches a global G3 rating, reflecting a species under pressure continent-wide, largely from wind-turbine collision mortality during migration. All 10 of the state’s records come from iNaturalist with no GBIF specimen data at all, meaning what’s known here traces entirely to people photographing or detecting the bat directly.

Records are thin and scattered, a July peak of 4 sightings against isolated single records in February and September, too sparse to describe a confident seasonal pattern beyond the July cluster likely reflecting the bat’s presence during the summer breeding season before it heads south.
