Pallid bat roosting ecology along the Purgatoire River

In an attempt to locate maternity colonies in southeastern Colorado I visited the Purgatoire River to capture and telemeter Townsend's big-eared bats. There are several Townsend's maternity colonies in this region of Colorado, and there may be others yet undiscovered.

Unfortunately no Townsend's bats were captured, but male pallid bats were captured repeatedly. Given their similar size and paucity of male roosting information I attached telemeters to approximately a dozen individuals.

Much thanks to the Wootens for their hospitality and to the Colorado Division of Wildlife for funding.
