Red Sea Swallowとは 意味・読み方・使い方

The Red Sea Swallow (Hirundo perdita) is a species of bird in the Hirundinidae family. It is possibly endemic to Sudan. It is known only from a single specimen, found in May 1984 at the Sanganeb lighthouse, north-east of Port Sudan, Sudan. However, this enigmatic swallow probably still exists, but the lack of recent records is puzzling. Unidentified swallows have been sighted in Lake Langano (c.20 birds) and in Awash National Park (3-8 birds) in the Rift Valley in Ethiopia, and these could possibly be this species. It is alternatively placed in the genus Hirundo.
