The figbirds are a genus (''Sphecotheres'') of orioles found in wooded habitats in Australia, Papua New Guinea and the Lesser Sundas. The three species have been considered conspecific, but today all major authorities consider them as separate species.〔Higgins, P. J., L. Christidis, & H. A. Ford (2008). Family Oriolidae (Orioles).

ISBN 978-0-643-06511-6〕 The split is primarily based on differences in measurements and plumage, and on biogeography. Compared to the "typical" orioles of the genus ''Oriolus'', the figbirds are more frugivorous (though they also take some small insects, nectar and seeds) and gregarious, even breeding in small, loose colonies (at least the Australasian figbird; nesting habits still unknown for the remaining).〔 They are strongly sexually dimorphic, with males having olive-green upperparts, a black head, and (uniquely for the family) distinct bright red facial skin.〔Simpson, K.

''A Guide to the Birds of Wallacea.'' Dove Publications Pty. Ltd. ISBN 0-9590257-3-1〕 Females are drab-coloured, being dull brownish above, and white below with strong dark streaking. They have greyish facial skin, and a greyish-black bill.〔〔 ==Species== Species in the genus ''Sphecotheres'' listed in taxonomic order:〔〔 * Green figbird or Timor figbird, ''Sphecotheres viridis''. * Wetar figbird, ''Sphecotheres hypoleucus'' * Australasian figbird, ''Sphecotheres vieilloti'' * * Yellow figbird, ''Sphecotheres (vieilloti) flaviventris'' * * Green figbird or southern figbird, ''Sphecotheres (vieilloti) vieilloti'' 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「Figbird」の詳細全文を読む スポンサード リンク
