Habitat and Ecology [top]

Habitat and Ecology: E. hansae flies in the upper levels of the canopy (Fenton, 1972); occurs in tropical forests off coastal areas (Alvarez-Castañeda and Alvarez, 1991); in the eastern Brazilian highlands, and coast and in the Amazon Basin and Atlantic Forest biomes (Koopman, 1982; da Fonseca et al., 1996). In Venezuela, it has been observed over ponds, large clearings, and evergreen forests; roosting inside a cavity located in a dead standing tree in a large lagoon (Handley, 1976). In Peru, E. hansae flew over a small river bordered by tall, tropical, lowland forest in hilly terrain (Graham and Barkley, 1984). In Bolivia, this bat occurred in a savanna area near the edge of a forest (Ibañez and Ochoa, 1989). The stomach of a specimen from Bolivia contained Orthoptera (Anderson, 1997).
