Geographic Range [top]

Range Description:This species is found in Central and South America. This species ranges from Jalisco and Veracruz (Mexico) to Bolivia, Guianas, and eastern Brazil south to Rio de Janeiro, Trinidad and Tobago (Simmons 2005). It is widely distributed at low elevations, generally below 500 m asl (Eisenberg 1989).

Population [top]

Population:This species is common in lowland evergreen and semi-deciduous forest and forest edge. It is rare in dry deciduous forest (Reid 1997).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This bat usually forages near streams and in moist areas. It prefers multistratal evergreen forest and forage in clearings and forest edges and forest corridors (Eisenberg 1989). Clearings and corridors are both natural and man made. In Mexico it has also been reported for secondary forests, croplands and grasslands (de Grammont pers. comm.). Roosting colonies average about 12 individuals. It may roost with other species in hollow trees or caves. Males defend harems, they have well-developed wing sacs in their ante-brachial membranes and emit scent while flapping their wings in ritualized combat (Bradbury and Emmons 1974). This species is an aerial insectivore that forages in background cluttered space.

Use and Trade [top]

Use and Trade: This species is not used.

Threats [top]

Major Threat(s): In general, deforestation is a potential threat in the region but this is probably not specific to any species of New World emballonurid bat because none of them have a restricted area of endemism, other than perhaps Balantioperyx infusca and Saccopteryx antioquensis.

Conservation Actions [top]

Conservation Actions: Retention of primary forest is the recommended conservation action. This species occurs in some protected areas, as with most New World emballonurid bats because they are usually widely distributed.
