Taxonomic Notes: This may be a complex of two distinct species, with Chaerephon nigeriae in the north of the known distribution and C. spillmani in the south. We follow Simmons (2005) in currently recognizing spillmani Monard, 1933 as a subspecies of nigeriae.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2017
Date Assessed: 2016-08-31
Assessor(s): Monadjem, A., Bergmans, W., Hutson, A.M., Cotterill, F. & Mickleburgh, S.
Reviewer(s): Piraccini, R.
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Geographic Range [top]

Range Description:This species is widely distributed over much of sub-Saharan Africa. It ranges from Sierra Leone in the west to Ethiopia in the east, being recorded as far south as Angola, Botswana and Zimbabwe. There are some additional records from the Arabian Peninsula in Yemen and western Saudi Arabia. Animals have been found at elevations of up to 1,000 m Asl, and possibly occur higher than this.
Countries occurrence:
Angola; Botswana; Burkina Faso; Cameroon; Chad; Congo, The Democratic Republic of the; Ethiopia; Ghana; Malawi; Namibia; Nigeria; Sierra Leone; South Sudan; Tanzania, United Republic of; Zambia; Zimbabwe

Population [top]

Population:This species is typically found in small groups of 10 to 15 animals, with maternity roosts being formed of up to 25 bats.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This is a savanna woodland species associated with Brachystegia woodlands in the southern portion of its range (Willis et al. 2002; Skinner an Chimimba 2005). In Nigeria, animals have been found in the Guinea and Sudan savannas extending southwards into cleared areas of tropical moist forest (Happold 1987; Willis et al. 2002). During the day this species has been recorded roosting in groups under tree bark an in the roofs of houses (Happold 1987; Ansell 1960; Skinner and Chimimba 2005).

Threats [top]

Major Threat(s): There appear to be no major threats to this species. The ability of the species to exploit buildings as roosts, and its association with cleared rainforest in Nigeria, suggests that it is relatively resistant to anthropogenic impacts (Willis et al. 2002).

Conservation Actions [top]

Conservation Actions: In view of the species wide range, it is presumably present in some protected areas. No direct conservation measures are currently needed for this species as a whole.
