Population [top]

Population: This bat is indistinguishable in the field from C. paranus. Aerial insective, appears to be rare but may be a relict of sampling bias.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: It occurs at low elevations in association with multistratal tropical forest in Venezuela (Handley 1976); present in deciduous and evergreen forest and clearings, often near water (Reid 1997). It has been found roosting in small groups (Reid 1997) or in colonies of fifty to seventy-five (Goodwin and Greenhall 1961) in hollow branches and buildings (Reid 1997). Activity begins soon after sunset; most records are from individuals caught in mist nets set over streams or ponds (Gardner et al. 1970; Valdez and LaVal 1971).
Systems: Terrestrial

Threats [top]

Major Threat(s): Deforestation.
