''Sporophila'' is a genus of Neotropical birds in the family Thraupidae. The seed finches are sometimes also included in this genus.〔South American Classification Committee (2007). ''(Incluir el género Oryzoborus dentro de Sporophila. )'' Accessed 19 January 2010.〕 They are relatively small with stubby, conical bills adapted for feeding on seeds and alike. Most species are strongly sexually dimorphic, and while "typical" adult males often are distinctive, female and immatures of both sexes can be very difficult (in some species virtually impossible) to identify to exact species.〔Ridgely, R. S., & G. Tudor (1989). ''The Birds of South America.'' Vol. 1. Univ. Texas Press, Austin〕 Females of at least some of these species have different ultraviolet colours, which can be seen by birds, but not humans.〔Benites, P., Eaton, M. D., Lijtmaer, D. A., Lougheed, S. C. & Tubaro, P. L. (2010). ''Analysis from avian visual perspective reveals plumage colour differences among females of capuchino seedeaters (Sporophila).'' J. Avian Biology. 41: 597–602.〕 Female-like (paedomorphic) males apparently also occur, at least in some species.〔Areta, J. I. (2009). ''Paedomorphosis in Sporophila seedeaters.'' Bull. B.O.C. 2009 129(2): 98-103.〕 ==Species== There are more than 30 species of ''Sporophila:'' * Buffy-fronted seedeater, ''Sporophila frontalis'' * Temminck's seedeater, ''Sporophila falcirostris'' * Slate-coloured seedeater, ''Sporophila schistacea'' * Plumbeous seedeater, ''Sporophila plumbea'' * Tropeiro seedeater, ''Sporophila beltoni'' * Caquetá seedeater, ''Sporophila murallae'' * Grey seedeater, ''Sporophila intermedia'' * Wing-barred seedeater, ''Sporophila americana'' * Variable seedeater, ''Sporophila corvina'' * White-collared seedeater, ''Sporophila torqueola'' * Rusty-collared seedeater, ''Sporophila collaris'' * Lesson's seedeater, ''Sporophila bouvronides'' * Lined seedeater, ''Sporophila lineola'' * Black-and-white seedeater, ''Sporophila luctuosa'' * Yellow-bellied seedeater, ''Sporophila nigricollis'' * * Hooded seedeater, ''Sporophila melanops'' – possibly extinct (20th century?), a hybrid or a color morph of ''S. nigricollis'' * Dubois's seedeater, ''Sporophila ardesiaca'' – possibly a subspecies or color morph of ''S. nigricollis'' * Double-collared seedeater, ''Sporophila caerulescens'' * White-throated seedeater, ''Sporophila albogularis'' * Drab seedeater, ''Sporophila simplex'' * White-bellied seedeater, ''Sporophila leucoptera'' * Parrot-billed seedeater, ''Sporophila peruviana'' * Black-and-tawny seedeater, ''Sporophila nigrorufa'' * Copper seedeater, ''Sporophila bouvreuil'' * Pearly-bellied seedeater, ''Sporophila pileata'' * Ruddy-breasted seedeater, ''Sporophila minuta'' * Tawny-bellied seedeater, ''Sporophila hypoxantha'' * Dark-throated seedeater, ''Sporophila ruficollis'' * Marsh seedeater, ''Sporophila palustris'' * Chestnut-bellied seedeater, ''Sporophila castaneiventris'' * Rufous-rumped seedeater, ''Sporophila hypochroma'' * Chestnut seedeater, ''Sporophila cinnamomea'' * Black-bellied seedeater, ''Sporophila melanogaster'' * Chestnut-throated seedeater, ''Sporophila telasco'' – the "Tumaco seedeater" is a stereotyped hybrid between this species and ''S. minuta'' 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「Sporophila」の詳細全文を読む スポンサード リンク
