Cormura brevirostris

Adult bats have a body length of 5 cm, a forearm of 4.5 cm and a weight of 9 g. The dorsal color varies from light brown to black, with no longitudinal stripes. The belly is paler than the back. They have elongated odorous sacs on the forearm. Shelters are usually hollowed out of trees. Groups are formed only by individuals of this species.

 

They are associated with humid environments with water courses in continuous forests. They forage along the entire vertical stratum of the forest, from the canopy to the ground level. The call is formed by three pulses of almost constant frequency. The average frequency of each pulse is increasing, the first one being near 25 kHz, the second frequency being 28 kHz and the third frequency being 30 kHz.

 

Its distribution includes Central America (from southeastern Nicaragua to Panama) and South America (Colombia, Venezuela, Guyana, Ecuador, Peru and Brazil).
