The crimson sunbird (''Aethopyga siparaja'') is a species of bird in the sunbird family which feed largely on nectar, although they will also take insects, especially when feeding young. Flight is fast and direct on their short wings. Most species can take nectar by hovering like a hummingbird, but usually perch to feed most of the time. Crimson sunbird is a resident breeder in tropical southern Asia from India to Indonesia. Two eggs or three eggs are laid in a suspended nest in a tree. This species occurs in forest and cultivation. Crimson sunbirds are tiny, only 11 cm long. They have medium-length thin down-curved bills and brush-tipped tubular tongues, both adaptations to their nectar feeding. The adult male has a crimson breast and maroon back. The rump is yellow and the belly is olive. The female has an olive-green back, yellowish breast and white tips to the outer tail feathers. In most of the range, males have a long green-blue tail, but ''A.s. nicobarica'' of the Nicobar Islands and the former subspecies ''A. vigorsii'' (Western crimson sunbird) of the Western Ghats of India lack the long central tail feathers. Their call is ''chee-cheewee''. The crimson sunbird has become the unofficial national bird of Singapore.〔 〕 File:Aethopyga siparaja seheriae Panchkhal Valley 01.jpg File:Aethopyga siparaja seheriae Panchkhal Valley 02.jpg Image:Aethopyga siparaja.jpg Image:Aethopyga_vigorsii_1.jpg Image:Aethopyga_vigorsii_2.jpg File:Aethopyga siparaja seheriae Panchkhal Valley 03.jpg File:Aethopyga siparaja seheriae Panchkhal Valley 04.jpg ==References== * ''Birds of India'' by Grimmett, Inskipp and Inskipp, ISBN 0-691-04910-6 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「crimson sunbird」の詳細全文を読む スポンサード リンク
