Keen’s long-eared bat has long ears and short, broad wings. It occurs along the Pacific coast of northwestern North America and can be difficult to distinguish from a similar relative.
Its wings are short and broad, and its ears are long. It closely resembles the related Myotis evotis, which can make field identification difficult.
It roosts in rock crevices and beneath boulders, and has also been found in trees, buildings, and under bridges. Foraging records include estuaries, riparian areas, and urban sites.
An extinction-risk assessment has not been added yet.
