Kirt's big-eared bat is a small bat with very long ears. It lives in coniferous forests in the west of North America and hunts insects at night using echolocation.
Kirt's big-eared bat differs from related species by its particularly long ears and dark coloration. It is important for nature because it destroys a large number of harmful insects in forest ecosystems.
