Scientific Name: Saccopteryx bilineata

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 Least Concern as it is widespread and is relatively habitat tolerant, which means that the species is tolerant to some habitat modification.

Geographic Range [top]

Range Description: This species is found in Central and South America. This species ranges from Jalisco and Veracruz (Mexico) to Bolivia, Guianas, and eastern Brazil south to Rio de Janeiro; Trinidad and Tobago (Simmons 2005). It is widely distributed at low elevations, generally below 500 m (Eisenberg 1989).

Population [top]

Population: S. bilineata is common in lowland evergreen and semideciduous forest and forest edge; rare in dry deciduous forest (Reid 1997).
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: These bats usually forage near streams and in moist areas; they prefer multistratal evergreen forest and forage in clearings and forest edges and forest corridors (Eisenberg 1989). Clearings and corridors are both natural and man made. Roosting colonies average about 12 individuals. These bats may roost with other species in hollow trees or caves. Males defend harems; they have well-developed wing sacs in their ante-brachial membranes and emit scent while flapping their wings in ritualized combat (Bradbury and Emmons, 1974). This species is an aerial insectivore that forages in background cluttered space. In Mexico it has also been reported for secondary forests, crop-lands and grasslands (de Grammont pers. comm.)
Systems: Terrestrial

Threats [top]

Major Threat(s): This is a widely distributed and common species. 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: This is a widely distributed and common species. Retention of primary forest. The species occurs in some protected areas. This occurs for most New World emballonurid bats because they are usually widely distributed.
