 All calls are multi-harmonic with most energy concentrated in the second harmonic.The currently known range of this species extends from the Caribbean lowlands of Costa Rica through Guyana to the state of Para, Brazil and has never been found in elevations below 300 m.

The exact population size of the short-eared bat are unknown, but this is one of the rarest Neotropical bats, know from fewer than twenty individuals taken from less than ten localities in humid lowland areas (Emmons and Feer 1997; Reid 1997).The one of the rarest, these bats have no immediate threats and is listed as Least Concern because it is widely distributed and is unlikely to be declining fast enough to qualify for inclusion in the threat categories.
