Northern hoary bats carry a NatureServe S3B vulnerable breeding rank in New York that matches a global G3 rating, reflecting a species under pressure continent-wide, largely from wind-turbine collision mortality during migration. The record leans overwhelmingly on GBIF (149 of 157 records), meaning survey and specimen data, not casual sightings, documents nearly everything known about this solitary, foliage-roosting bat here.

July and August together account for 114 of the 157 records, nearly three-quarters of the entire year’s total, an extraordinarily concentrated summer peak that tracks the maternity season; the record shows nothing at all in April and December, consistent with a bat that’s largely absent from New York outside its brief summer residency.
