Townsend's maternity colony

While birding in eastern Washington near Spokane, Washington Department of Fish and Wildlife biologist Howard Ferguson came across a Townsend’s Big-eared Bat stuck on a teasel bush! Desperately dehydrated, it died despite the water he gave it. On inspection, Howard discovered it was a juvenile and figured the colony must be nearby. So he started searching and found an old log cabin housing a large maternity colony.

The Townsend's Big-eared Bat (Corynorhinus townsendii) is considered one of the rarest mammal species in the northwest. It relies heavily on caves and mines for roost sites and is very sensitive to disturbances. Although it seems to shun bat houses, occasionally it has been found roosting in old buildings. Of the twelve maternity roosts known in Washington, only two are in the eastern part of the state, both in man-made structures.

See the BATCAM and read more about how Howard and BNW worked together with other bat conservation groups to help protect this rare Townsend's maternity colony.
