Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Kock, D., Amr, Z., Mickleburgh, S., Hutson, A.M. & Bergmans, W.
Reviewer(s): Hutson, A.M., Racey, P.A. (Chiroptera Red List Authority) & Temple, H. (Global Mammal Assessment Team)
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.

Habitat and Ecology [top]

Habitat and Ecology:This is a gregarious and colonial species which occurs in crevices or in cliffs in arid and semi-desert habitats. It roosts in temples, caves, mines, open-wells, underground irrigation tunnels and old tombs and buildings. Forages over desert and semi-desert vegetation zones, mainly in oases. Forages by slow hawking, has been observed foraging around palm trees and buildings, and over water.

Threats [top]

Major Threat(s): The main threat is the widespread use of pesticides against locusts. Human disturbance in caves and old buildings is affecting some populations.

Conservation Actions [top]

Conservation Actions: It presumably occurs in several protected areas. Underground roost management is needed in some places. A study on the impacts of pesticides is required, especially ways in which the impact might be minimised.
