New York’s 91 American ermine records come almost entirely from iNaturalist (87 of them), so photographs, not trapping and specimen surveys, document most of what’s known about this weasel in the state. No NatureServe rank appears on file here. Tompkins County leads the county list with 15 records, followed by Albany with 8, and Five Rivers Education Center and Reinstein Woods Nature Preserve tie as the most often named places.
July carries the most records, 19 of the 91, with a smaller rise in May and none at all in February; that summer peak likely tracks the weeks after this year’s kits become mobile enough to be seen, when more people are also out on the trails to photograph them.
