The pale-breasted spinetail (''Synallaxis albescens''), is a passerine bird which breeds in the tropical New World from Costa Rica to central Argentina, and in Trinidad. It is a member of the South American bird family Furnariidae, a group in which many species build elaborate clay nests, giving rise to the English name for the family of "ovenbirds". However, the pale-breasted spinetail constructs a spherical stick nest with a 30 cm long tubular entrance low in a bush, into which its two greenish white eggs are laid. This species is a widespread and common resident breeder in a range of grassy and scrub habitats. The pale-breasted spinetail is typically 16.5 cm long, and weighs 15 g. It is a slender bird with a medium long tail. The upperparts plumage is mainly pale brown, with darker wings and tail and rufous crown and shoulder patches. The throat and underparts are whitish with browner flanks. Sexes are similar, but the race ''josephinae'' has grey on the forecrown, face sides and chest. The pale-breasted spinetail is an insectivore which is difficult to see as it forages deep in thickets, but may be located by its buzzy repetitive ''wait'here'' song. == 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「Pale-breasted spinetail」の詳細全文を読む スポンサード リンク
