Least weasels are North America’s smallest carnivore, and Iowa’s record for the species is tiny: 8 records since 2000, all logged on iNaturalist and 4 of them also in GBIF, one apiece from eight counties. That’s a thin showing for an animal this small and fast, which 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 across six months, a pair each in February and December and single sightings in March, April, June, and September, too sparse a pattern in a count this small to describe any real seasonal trend.
