Animalia Chordata Mammalia Chiroptera Rhinolophidae

Scientific Name: Rhinolophus alcyone Temminck, 1852
Common Name(s):
English Halcyon Horseshoe Bat
Taxonomic Notes: There are considerable colour differences between the western and eastern populations of this bat, suggesting that there may be a need to re-examine the taxonomic status of these two groups.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2017
Date Assessed: 2016-08-31
Assessor(s): Monadjem, A., Taylor, P.J., Jacobs, D. & Cotterill, F.
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 sub-Saharan bat species ranges through much of West and Central Africa. It has been recorded from Senegal in the west through to Togo, and then from Nigeria to southern Sudan and western Uganda, with patchy records from the Congo basin (although it likely occurs throughout the Congo). It ranges as far south as central Democratic Republic of the Congo. The record of this species from Gabon needs to be reexamined as it may represent a misidentified specimen of Rhinolophus sylvester (Dowsett et al. 1991).
Countries occurrence:
Cameroon; Congo; Congo, The Democratic Republic of the; Côte d'Ivoire; Equatorial Guinea; Ghana; Guinea; Liberia; Nigeria; Senegal; Sierra Leone; South Sudan; Togo; Uganda

Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is associated with closed tropical moist forest, but also extends into savanna where there are pockets of suitable habitat (Grubb et al. 1998). During the day colonies roost in caves, hollow trees, the roofs of thatched houses and in old mine shafts (Rosevear 1965; Brosset 1966; Happold, 1987).
Generation Length (years):7.47

Threats [top]

Major Threat(s): This widespread species is threatened in parts of its range by habitat loss, largely resulting from logging and conversion of land to agricultural use. In some areas the species is hunted for food, although it is unclear whether this represents a major threat.

Conservation Actions [top]

Conservation Actions: It is not known if the species is present in any protected areas. Further studies are needed into the taxonomy and distribution of this species.
