Types of Bats in Washington (Identification Guide)
Learn the main bat species in Washington state along with simple ways to tell them apart using size, color, and habitat clues.
Washington state hosts several bat species including the little brown bat and big brown bat. Identification uses body size, ear length, fur tone, and flight patterns to tell them apart. These nocturnal flyers help keep insect numbers in check across forests, farms, and cities. Spotting them often starts with listening for high pitched calls at dusk near water sources.

The little brown bat stands out with its small size and glossy brown fur. It roosts in attics and trees during summer. The big brown bat grows larger with broader wings suited for open fields. Townsend big eared bats show long ears and prefer caves. Yuma myotis often hunts over lakes and streams. Each one follows distinct seasonal movements that locals track year after year.
How Can I Identify Bats by Sight and Sound in Washington?
