Long-tailed weasels carry a NatureServe S2 imperiled rank in Nebraska despite the record showing 117 total sightings, one of the larger counts in this tier, a reminder that a healthy record count doesn’t equal a secure population. 115 of those records come from GBIF rather than iNaturalist, meaning trapping data, not casual sightings, dominates what’s documented.

Records show two peaks, February (17) and July (18), together nearly a third of the year’s total, tracking late-winter fur-trapping season and peak summer activity when this year’s young become mobile enough to be trapped or spotted alongside a parent.
