Species Authority: Fry & Smith, 1985
Common Name(s):
English Red Sea Swallow, Red Sea Cliff-swallow, Red Sea Cliff Swallow
French Hirondelle de la Mer Rouge
Taxonomic Notes: The BirdLife Taxonomic Working Group is aware that phylogenetic analyses have been published which have proposed generic rearrangements which may affect this species, but prefers to wait until work by other taxonomists reveals how these changes affect the entire groups involved.
Identification information: 15cm. Only known from the type specimen. Steely blue crown, blackish forehead, lores, throat and upper breast, restricted white chin and grey rump.  Similar spp Most closely resembles South African Cliff Swallow Hirundo spilodera but has rump grey not rufous and blackish throat.

Geographic Range [top]

Range Description: Hirundo perdita is known only from the type-specimen, found dead in May 1984 at Sanganeb lighthouse, north-east of Port Sudan, Sudan (Fry and Smith 1985). It is judged most likely to be found in the Red Sea hills of Sudan or Eritrea, or possibly (because two pale-rumped swallows were seen flying out over the Red Sea towards Jedda, just before the discovery of the type) in the coastal hills of western Saudi Arabia north of Jedda (Madge and Redman 1989). Unidentified cliff swallows, possibly of this species, have been seen at Lake Langano (c.20 birds) and in Awash National Park (3-8 birds) in the Rift Valley in Ethiopia, plus three more recent sites (P. Robertson in litt. 1998), although they are more likely to represent an undescribed taxon. There is no other information on the species's range, population size and trend, preferred habitat and potential threats.
