Red-chested swallow : ウィキペディア英語版 | Red-chested swallow
The red-chested swallow (''Hirundo lucida'') is a small non-migratory passerine bird found in Africa, specifically West Africa, the Congo basin and Ethiopia. It has a long, deeply forked tail and curved, pointed wings. It was formerly considered a subspecies of the closely resembling barn swallow, however, the adult red-chested swallow differs in being slightly smaller than its migratory relative, in addition to having a narrower blue breast band and shorter tail streamers; juveniles are more comparable to barn swallow chicks. ==References== 〔
