Population severely fragmented: No

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. It is common only where there are caves or rock crevices, and  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 (Tuttle 1970, Handley 1976, Gardner 1977, Wilson 1979, Emmons and Feer 1997, Reid 1997).
Systems: Terrestrial

Use and Trade [top]

Use and Trade: This species is not used.

Threats [top]

Major Threat(s): There are no major threats to this species. Cave mining and tourism could be a threat. There is habitat loss in Mexico (Arroyo-Cabrales pers. comm.).

Conservation Actions [top]

Conservation Actions: It occurs in a number of protected areas throughout its range. The recommended conservation action is to protect the caves where this species is found.
