The giant conebill (''Oreomanes fraseri'') is a small passerine bird, one of the tanager family. The only member of the genus ''Oreomanes'' it is closely related to the regular conebills ''Conirostrum'' though it differs in its larger size and nuthatch-like foraging habits. The giant conebill is in length and weighs . It is grey above, deep chestnut below, and with a white patch on the cheeks. It is found in the Andes from Colombia to Ecuador, and Peru to Bolivia. It lives in ''Polylepis'' trees of the family Rosaceae. The giant conebill lives individually or in groups of 5 or less. It peels bark off ''Polylepis'' trees to find insects. It also eats aphids and sugary solutions secreted by ''Gynoxys''. The species is a seasonal breeder, nesting at the start of the rainy season (September to December in Bolivia where it has been studied). The nest is an open cup set on the branches of ''Polylepis'', and the average clutch size is 1.8 eggs. Both parents incubate the eggs, feed the chicks and remove the faecal sacs. Its decline is attributed to the destruction and fragmentation of ''Polylepis'' woodland. The binomial commemorates the British zoologist Louis Fraser. ==Footnotes== 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「giant conebill」の詳細全文を読む スポンサード リンク
