Long-tailed weasel sightings in Utah spread widely, from the Uinta-Wasatch-Cache National Forest, which alone accounts for 14 of the state’s top-place records, down through Bear River Migratory Bird Refuge, Cedar Breaks National Monument, and Antelope Island. That range mirrors the weasel’s own habits: it hunts along meadow edges and streams that connect valley wetlands to mountain forest rather than sticking to one elevation band.
Of Utah’s 383 recorded sightings, 297 came from iNaturalist, an unusually photo-heavy split for a small, fast-moving carnivore, and the most recent sighting was logged in July 2026. Reports run all year but climb into a clear July peak of 64, with May and August close behind, likely tracking both the weasel’s own activity and when people are out on the trails where it turns up.
NatureServe ranks the long-tailed weasel S4, Apparently Secure, in Utah, the healthiest standing of any mustelid covered in this set of records.
