The complete county distribution, spread across 6 Nebraska counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Every one of Nebraska’s 31 tricolored bat records comes through GBIF rather than a photograph, a species so thinly documented by casual sightings that its NatureServe S3 vulnerable rank, matching G3 global rank, and IUCN Vulnerable status all point to the same story: white-nose syndrome has hit this bat hard across its range since the disease began spreading.

January alone accounts for 13 of the state’s 31 records, more than 40 percent of the total, an unusual mid-winter peak that likely reflects hibernaculum survey timing, when researchers count bats roosting in caves, rather than the bat’s own visibility, since tricolored bats are otherwise dormant during that month.
