The seedeaters are a form taxon of seed-eating passerine birds with a distinctively conical bill. Most are Central and South American birds that were formerly placed in the American sparrow family (Emberizidae), but are now known to be tanagers (Thraupidae) closely related to Darwins finches. Indeed, some of the birds listed here seedeaters are closer to these "finches", while the more "true" seedeaters form a clade with some tanagers. A few "atypical" seedeaters are closely related to certain tanagers, many of which (such as the flowerpiercers) have peculiarly adapted bills. In addition, there are some African passerines called seedeaters. They belong to the serin genus (''Serinus'') of the true finch family (Fringillidae), but might need to be separated with their closest relatives in ''Crithagra''. ==American seedeaters== True seedeaters * ''Amaurospiza'' – blue seedeaters (4 species, tentatively placed here) * ''Dolospingus'' – white-naped seedeater * ''Oryzoborus'' – seed-finches (6 species, sometimes included in ''Sporophila'') * ''Sporophila'' – typical seedeaters (some 30 species, 1 possibly recently extinct) Related to Darwin's finches * ''Euneornis'' – orangequit * ''Loxigilla'' – Antillean bullfinches (4 species) * ''Loxipasser'' – yellow-shouldered grassquit * ''Melanospiza'' – St. Lucia black finch * ''Melopyrrha'' – Cuban bullfinch * ''Tiaris'' – typical grassquits (5 species) Atypical seedeaters * ''Acanthidops'' – peg-billed finch * ''Catamenia'' (3 species) * ''Haplospiza'' (2 species) Relatives of true seedeaters These tanagers are the true seedeaters' closest relatives: * ''Charitospiza'' – coal-crested finch * ''Lophospingus'' (2 species) * ''Sicalis'' – yellow-finches (12 species) * ''Volatinia'' – blue-black grassquit 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「seedeater」の詳細全文を読む スポンサード リンク
