The scarlet-headed blackbird (''Amblyramphus holosericeus'') is an icterid bird of southern South American wetlands. This species is about 24 cm long. The bill is oddly shaped: long, slender, and very sharp, looking almost upturned. Adults of both sexes are described by their name. Juveniles have entirely black plumage; orange-red feathers first appear on their breast and throat, later spreading to the neck, head, and thighs. The song is given as "loud, clear, and melodic, a ringing 'cleer-cleer-clur, clulululu'." Calls are simpler but have a similar quality. Scarlet-headed blackbirds occur in pairs in large reed beds in southern Brazil, Paraguay, Uruguay, and northeastern Argentina; Bolivia has an isolated population at altitudes up to about 600 m. They often perch conspicuously on top of stems. They are uncommon, particularly away from the coast.〔 They eat mainly fruit, supplementing it with seeds and invertebrates, especially insects. They use their bill as a hammer to open food items. Scarlet-headed blackbirds are monogamous, and territories are grouped together. The nest is an open cup placed in the crotch of a shrub or woven into vegetation, in which they lay two eggs.〔 ==References== 〔 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「Scarlet-headed blackbird」の詳細全文を読む スポンサード リンク
