Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Sampaio, E., Lim, B., & Peters, S.
Reviewer(s): Medellín, R. (Chiroptera Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
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 threat categories.
Previously published Red List assessments:
1996 Lower Risk/least concern (LR/lc)

Habitat and Ecology [top]

Habitat and Ecology: It occurs in moist habitats and is strongly associated with multistratal evergreen forests (Eisenberg 1989). Roosting groups range from one to nine bats (Eisenberg 1989). S. leptura feed on small to tiny insects, including moths; they come out to forage during the last daylight and fly in beats, repeating the same path again and again (Emmons and Feer 1997). The species forages throughout the night. 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). This species is an aerial insectivore that forages in background cluttered space. It is not too abundant in Belize (Miller pers. comm.). It has been also reported in Mexico in secondary forests, crop-lands and grasslands (de Grammont pers. comm.).
Systems: Terrestrial

Threats [top]

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

Conservation Actions [top]

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