Eumops auripendulus

Black Bonneted Bat

Order: Chiroptera
Family: Molossidae


Conservation Status: Least Concern.

This free-tailed bat has large, rounded ears that frame its face like a sunbonnet. It has soft, thick fur, big teeth, and a comparatively big skull. It does not always hang head-down to roost, but instead may crawl into a small space - for example, under a corrugated tin roof - and, if bothered, crawl away. This species is not well known. Most have been found in deciduous or semi-deciduous forests. One was spotted hunting over a highway.

As with other bats in the family Molossidae, about half the long, thick tail is within the tail membrane and the rest extends beyond it. The flight of molossid bats tends to be fast and erratic.

Range: Head and Body: 75-92 mm; Tail: 43-54 mm

Range: 25-35 g
