Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Mancina, C. & Incháustegui, S
Reviewer(s): Medellín, R. (Chiroptera Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
This species is listed as Least Concern in because of its wide distribution, presumed large population, occurrence in a number of protected areas, tolerance to some degree of habitat modification, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

Population [top]

Population:This bat is rare and local in southeastern Mexico and possible north Central America; large aggregations are found in parts of west Mexico (Arroyo-Cabrales pers. comm.). Very common in Cuba and Dominican Republican (Mancina and Inchaustegui pers. comm.).
Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is found in dry areas, rarely in evergreen, lowlands forest (Reid, 1997). It roosts in large caves and mine tunnels, occasionally in buildings, in groups of 1 to 500. Individuals hang by one or both feet from high ceilings near the roost entrance and do not cluster. This species does not crawl on feet and thumbs like many bats, but can walk rapidly in an upside-down position. Activity starts 1 to 2 hours after sunset; when foraging, flight is slow and maneuverable, usually within 1 m of the ground. Fruit and insects are eaten; animal prey is gleaned by mouth from the ground or vegetation and carried to a night roost (Reid, 1997). A second foraging flight occurs about 2 hours before sunrise (Reid, 1997).
