Northern hoary bats carry a NatureServe S4 apparently secure rank in Iowa despite the species’ G3 global rank, which reflects continent-wide pressure from wind-turbine collision mortality during migration. All 7 of the state’s records come from iNaturalist with no GBIF specimen data, meaning what’s documented here traces entirely to people photographing or detecting the bat directly.
Records cluster entirely in summer, June through August account for all 5 of the monthly-tallied sightings, fitting the window when this solitary, foliage-roosting bat is present for the breeding season before it heads south for winter; the record shows nothing outside that three-month stretch.
