Population [top]

Population: This bat species was poorly studied until a few years ago, but the German-Mexican team as part of the Program for Mexican Bat Conservation (PCMM) has carried out new studies. It is considered an uncommon species (Arroyo-Cabrales pers. comm.). They roost in small groups. They may have to undertake small-scale seasonal migrations in order to find flowering plants. They do not hibernate (Bergstresser 2002).
Current Population Trend: Decreasing
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: This species has been found roosting in a sheltered, but not secluded, rocky overhang above a stream in a canyon. In addition, this bat was found roosting in a culvert and in a cave. Apparently, its occurrence is restricted to the arid thorn and tropical deciduous forest along the coast. These habitats have a clear summer rainy season (from July to October) and a remarkably dry season (from November to May). During this last period the majority of the trees lose their leaves. The dominant species in these habitats are Cordia alliodora, Caesalpina eriostachys, Lysiloma divaricata, Brosimun alicastrum, Tabebuia donnell-smithi. Reproductive records are limited. Two pregnant females were collected in Colima in September. A female captured in August was lactating (Tellez and Ortega, 1999).
Systems: Terrestrial

Threats [top]

Major Threat(s): Habitat loss including fires (Arroyo Cabrales pers. comm.).

Conservation Actions [top]

Conservation Actions: The species is including inside the Mexican regulation for species conservation NOM-59-SEMARNAT-2001 (under P categorie which means Endangered of extinction). It is found in at least two proteced areas (Cuenca de los Rios Valle de Bravo, Malacatepec, Tilostoc y Temascaltepec and Chamela-Cuixmala Reserve). The protection of this species is being undertaken by the Program for Mexican Bat Conservation (PCMM) (Arroyo-Cabrales pers. comm.).
