Population [top]

Population:It is uncommon but widespread. These bats may be geographically limited to areas with caves or rocks (Emmons and Feer 1997). It can be locally abundant near caves where roosting occurs with up to 500 individuals (Lassieur and Wilson 1989).
Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is strongly associated with moist habitats and is most frequently encountered in multistratal tropical forest (Eisenberg and Redford 1999). It is usually found in mature, evergreen forest, occasionally deciduous forest and agricultural areas (Reid 1997). This bat is an aerial and gleaning insectivore, it occasionally consumes fruits. It roosts in caves or tunnels, such as mine tunnels and forms colonies of 12 to 25, sometimes up to hundreds (Goodwin and Greenhall 1961, Reid 1997, Eisenberg and Redford 1999). Activity begins well after sunset, in full darkness. This bat is an extremely agile flier and may stop and hover in front of a mist net or escape through small gasps. It is sometimes caught in nets across streams or paths through forest (Reid 1997).

Use and Trade [top]

Use and Trade: This species is not used.

Threats [top]

Major Threat(s): It is associated with cave and karstic habitats which may be threatened by disturbance within forests. In Bolivia this species is considered to be Vulnerable as it is not known from a protected area and it is in a fragile ecosystem.

Conservation Actions [top]

Conservation Actions: Conservation of caves and karstic habitats is the recommended conservation action. This species occurs in a number of protected areas throughout its range, including in Belize (Miller pers. comm.). In Mexico is listed as threatened under NOM - 059 - SEMARNAT - 2001 (Arroyo-Cabrales pers. comm.).
