Canyon bat records fit the sheer walls and warm desert basins of Glen Canyon and Capitol Reef. North America’s smallest bat slips into narrow rock crevices for shelter and often emerges early in the evening to take tiny flying insects over washes and water. Its pale coat also suits Utah’s light-colored desert rock.

July produces the most of 437 reports, when insects, acoustic survey work, and nighttime park access overlap. Record totals measure those encounters, not colony size. Because canyon bats may remain active on mild winter nights at low elevation while high-country bats are inactive, elevation and temperature are more informative than a simple statewide season.

NatureServe lists canyon bats as S4, apparently secure, in Utah, one of the steadier ratings among the state’s bat species. Most of the 437 Utah records come from GBIF rather than iNaturalist, a sign that targeted acoustic and mist-net surveys, not casual sightings, drive the count for a bat this small and fast-flying.
