Habitat and Ecology [top]

Habitat and Ecology: It is strongly associated with streams within tropical evergreen forest. It feeds on nectar, fruit, and pollen, and may visit flowers primarily to obtain insects. Plant species visited in Mexico include Agave, Ceiba, Calliandra, Eucalyptus, Ipomoea, Pinus, and various composites. It roosts in small groups in caves, tunnels or tree hollows and is found in lowland rainforest, deciduous forest, gardens, and plantations. A colony of about 75 was found in a tunnel in Peru, grouped into several small clusters and hanging from the ceiling. Although common only where there are caves or rock crevices, and they are rare or perhaps absent from lowland Amazonian forests lacking high ground, rocks, and caves. A single birth peak occurs each year, late in the wet season (Emmons and Feer, 1997; Gardner, 1977; Handley, 1976; Reid, 1997; Tuttle, 1970; Wilson, 1979).
Systems: Terrestrial

Threats [top]

Major Threat(s): No major threats. Cave mining and tourism can be a threat. Habitat loss in Mexico (Arroyo-Cabrales pers. comm.).

Conservation Actions [top]

Conservation Actions: Occurs in a number of protected areas throughout its range. Protect the caves.
