The nigritas or negrofinches are small passerine birds belonging to the genus ''Nigrita'' in the estrildid finch family Estrildidae. There are four species which occur in forest, secondary growth and scrubland in West, Central and East Africa. They are 10-15 centimetres long. The bill is short and black and is fairly slender in some species. The colour of the plumage varies but all have a dark tail. The upperparts are grey or brown and the underparts are black, grey, white or reddish-brown. The grey-headed negrofinch and male pale-fronted negrofinch have a black face and the white-breasted negrofinch has a black cap. Negrofinches have whistling or trilling songs and calls. They feed on insects, fruit and seeds. They often forage high in the treetops, usually alone or in pairs. ==Species list== * White-breasted nigrita, ''Nigrita fusconotus'' * Chestnut-breasted nigrita, ''Nigrita bicolor'' * Pale-fronted nigrita, ''Nigrita luteifrons'' * Grey-headed nigrita, ''Nigrita canicapillus'' 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「Nigrita (bird)」の詳細全文を読む スポンサード リンク
