English Lesser Sac-winged Bat

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2015

This species is listed as Least Concern as it is widespread, tolerant of a range of habitats and has a presumed large population. It is unlikely to be declining fast enough to be included in any of the threatened categories.

Population [top]

Population:This bat is widespread (Emmons and Feer 1997) at elevations below 500 m asl. This species is relatively common overall, but is not too abundant in Belize (Miller pers. comm.).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It occurs in moist habitats and is strongly associated with multistratal evergreen forests (Eisenberg 1989). It has been also reported in Mexico in secondary forests, crop-lands and grasslands (de Grammont pers. comm.). Roosting groups range from one to nine bats (Eisenberg 1989). It feeds on small to tiny insects, including moths. It comes out to forage during the last daylight and fly in beats, repeating the same path again and again (Emmons and Feer 1997). This species forages throughout the night as an aerial insectivore in background cluttered space. There is some shifting in the composition of the social group, males tend to defend individual females during breeding when they exist as monogamous pairs (Bradbury and Vehrencamp 1977).

Use and Trade [top]

Use and Trade: This species is not used.

Threats [top]

Major Threat(s): Forest loss through conversion to pasture and agriculture is the primary threat. It probably is a rainforest generalist but the loss of forest is more specific to areas of northern Brazil.

Conservation Actions [top]

Conservation Actions: The recommended conservation action is to reduce habitat conversion. In Mexico it is listed as subject to special protection under NOM - 059 - SEMARNAT - 2001 (Arroyo-Cabrales pers. comm.).
