The spectacled thrush, bare-eyed thrush, or yellow-eyed thrush〔(Yellow-eyed Thrush ), World Birds〕 (''Turdus nudigenis''), is a resident breeding bird in the Lesser Antilles and in South America from Colombia and Venezuela south and east to northern Brazil. In Trinidad and Tobago, this thrush is also known as big-eye grieve. The similar but allopatric Ecuadorian thrush was formerly considered a subspecies of the bare-eyed thrush and named ''T. n. maculirostris''; it is now normally separated as a good species ''T. maculirostris''. It has a narrower eyering and is only found in forest and woodland in western Ecuador and northwestern Peru. ==Description== The spectacled thrush is 23–24 cm long and weighs 60 g. It is plain olive-brown above and paler brown below. The throat is brown-streaked off-white, and the lower belly is whitish. It has a prominent yellow eye ring which gives rise to its English and scientific names. There are two poorly defined subspecies, differing mainly in the darkness of the plumage. Sexes are similar, but young birds are flecked above and spotted below, and have a thinner eye ring. The song is a musical warble, slower and lower pitched than that of the cocoa thrush (''T. fumigatus''), and it also produces a cat-like ''queeoow'' call and, when uncomfortable, emits a ''kereel''. 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「Spectacled thrush」の詳細全文を読む スポンサード リンク
