Determining the causes of mortality in endangered species is essential to understanding the possible reasons behind their decline and to facilitating the implementation of mitigating steps. The southern bent-winged bat (Miniopterus orianae bassanii) is a critically endangered Australian bat whose population numbers have decreased over the past 50 years. As part of a larger investigation to determine if disease could be a contributing factor to the decline, 27 southern bent-winged bats and one closely related eastern bent-winged bat (Miniopterus orianae oceanensis) that died during the study were necropsied and examined histologically. Trauma was the most common cause of death in the southern..View full abstract
