Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor/s: Sampaio, E., Lim, B., Peters, S., Miller, B., Cuarón, A.D. & de Grammont, P.C.
Reviewer/s: Medellín, R. (Chiroptera Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Justification:
This species is listed as Least Concern as it is widespread, and unlikely to be declining rapidly.

Geographic Range [top]

Range Description: This species is found in Central and South America. It's widely distributed from central Nicaragua through Panama; west of the Andes to northwestern Ecuador; and east of the Andes from Venezuela and the Guianas to Amazonian Peru, Brazil and Northern Bolivia (Wilson and Reeder 1993; Reid 1997; Eisenberg 1989; Tirira 1999). Found from lowlands to 1,000 m (Emmons and Feer 1997; Reid 1997; Linares 1998). Distribution follows moist lowland forest areas. Note that this species may no longer occur in the southernmost part of the range due to forest loss. It is found from Nicaragua south to Peru and Central Brazil (Simmons 2005).

Population [top]

Population: Locally common in the Amazon but generally understudied (Bernard pers. comm.). This species may be undersampled due to methodological issues.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: These bats are associated with streams and moist areas, preferably in lowland and multistratal tropical evergreen forests (Eisenberg 1989; Reid 1997). They live in the forest and forage in small open spaces, chiefly flying in long, slow, beats of about 20 m long between the forest canopy and subcanopy (Emmons and Feer 1997). Frequently recorded at forest edges. (Sampaio, pers comm.). Active soon after sunset, it feeds on small flying insects near forest edge or over water (Reid 1997). Cormura brevirostris has not been the subject of a detailed field study (Eisenberg 1989). It is an aerial insectivore of background cluttered space.
Systems: Terrestrial

Threats [top]

Major Threat(s): Deforestation. In general, deforestation is a potential threat to most organisms but is probably not specific to any species of New World emballonurid bats because none of them have a restricted area of endemism other than perhaps Balantioperyx infusca and Saccopteryx antioquensis.

Conservation Actions [top]

Conservation Actions: Retention of primary forest. Presumably the species occurs in some protected areas. This is true for most New World emballonurid bats because they are usually widely distributed.
