Least weasels are North America’s smallest carnivore, and Iowa’s record for the species leans heavily on GBIF specimen data, 31 records against just 8 from iNaturalist, since an animal this small and fast is far more likely to turn up in a trap than in a photograph. NatureServe rates the state population S3, vulnerable, fitting a species that’s genuinely difficult to survey and likely underrepresented even in this thin record.
Records are scattered evenly across just four months, February through April plus a single June sighting, too sparse a pattern in a dataset this small to describe any real seasonal trend beyond confirming occasional detection through the spring.
