Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-07-03
Assessor(s): Miller, B., Reid, F., Arroyo-Cabrales, J., Cuarón, A.D. & de Grammont, P.C.
Reviewer(s): Solari, S.
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:It is common in most of its range in rainforests of Mexico (Ceballos and Oliva 2005), but less common in dry forest (Reid 2009). In rainforests often it is more numerous than G. soricina. In South America the species seems to be rare; in Ecuador it is known from just one record (Tirira pers. comm.).
Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This bat occurs in a wide variety of tropical and subtropical habitats, including savanna, secondary riparian growth, xeric thorn forests, pine-oak forests, and both pristine and disturbed deciduous and evergreen rain and cloud forest, and clearings (Webster and Jones 1993). It roosts in hollow trees, caves, and tunnels (Reid 2009). In Mexico, most of the known records come from streams inside mature forests (Ceballos and Oliva 2005). The diet includes nectar and pollen of bananas and Mucuna, fruit of Acnistes, and moths (Howell and Burch 1974). Birth peaks have been recorded January to April and July to August (Webster and Jones 1993).
