The Fanti saw-wing (''Psalidoprocne obscura''), also known as the Fanti rough-winged swallow, is a small passerine bird in the swallow family. The Fanti saw-wing breeds in the lowlands of southern west Africa from Senegal to Cameroon. It is mainly resident, apart from seasonal movements. This bird is found in open country, including light woodland, near water. Fanti saw-wings are graceful flyers and they generally feed on insects, including beetles, while airborne. They are typically seen low over water or grassland. The lined nests are built in a 60 cm burrow in a vertical bank. The clutch is two eggs. This is a small swallow at 17 cm. Its plumage is glossy green. The tail is long and deeply forked. Sexes are similar, but the female has a shorter tail. Juveniles are brown with little gloss, and have short tails. ==References== * ''Birds of The Gambia'' by Barlow, Wacher and Disley, ISBN 1-873403-32-1 * ''Swallows and Martins'' by Turner and Rose ISBN 0-7470-3202-5 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Fanti saw-wing」の詳細全文を読む スポンサード リンク
