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., Miller, B., Cuarón, A.D. & de Grammont, P.C.
Reviewer(s): Medellín, R. (Chiroptera Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Justification:
This species is listed as Least Concern. Although it is uncommon, it is widespread and relatively habitat tolerant so presumed to have a large population overall, and is unlikely to be declining rapidly enough to qualify under a more threatened category.

Geographic Range [top]

Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: It has been taken in both moist and dry deciduous sites. It can be found in primary forest, secondary forest, forest fragments and pastures surrounding forest (Sampaio pers. comm.). In Venezuela, specimens have been observed roosting with other species in hollow trees (Handley, 1976). This bat eats insects (chiefly beetles, katydids, and Homoptera) arachnids, lizard, and some fruits (Bonaccorso, 1979). It is attracted by calling cicadas and the distress calls of small bats (Reid, 1997). It is usually caught in mist nets set over streams or across forest trails and usually travels in the subcanopy as opposed to the understory level (Reid, 1997). Two females from Peru were found to contain two embryos each (Gardner, 1976).
Systems: Terrestrial

Threats [top]

Major Threat(s): Habitat loss in some parts of its range though this is not considered a major threat.

Conservation Actions [top]

Conservation Actions: Reduce habitat loss. This species occurs in a number of protected areas throughout its range.
In Mexico is listed as threatened under NOM - 059 - SEMARNAT - 2001 (Arroyo-Cabrales pers. comm.).
