Characteristic Odors of Tadarida brasiliensis mexicana Chiroptera: Molossidae
Lawrence T. Nielsen, David K. Eaton, Donald W. Wright, and Barbara Schmidt-French

Abstract

The odors in a central Texas cave with a large roosting population of Mexican free-tailed bats (Tadarida brasiliensis mexicana) were identified and related to captive individual bats. Solid phase microextraction (SPME) was used to sample and concentrate the volatile organics from the cave and individual bats. Odors were detected organoleptically and simultaneously quantified and identified. The characteristic odor for T. b. mexicana is due principally to 2’-aminoacetophenone.
