The russet antshrike (''Thamnistes anabatinus'') is a passerine bird in the antbird family. It is the only member of the genus '' Thamnistes''. It is a resident breeder in the tropical New World from southern Mexico to northern Bolivia. It is a bird of forest, old second growth, semi-open woodland and edges up to altitude. The female lays two brown-speckled white eggs in a deep cup nest high in a tree, usually in a semi-open location. Nest-building, incubation, and care of the young are shared by both sexes. The russet antshrike is a small antbird, typically long and weighing . It has a heavy hooked bill and brown upperparts, becoming rufous on the wings and tail. It has a dark eyestripe and a buff supercilium. The underparts are olive buff. Sexes are similar, but the male has a concealed rufous-orange patch in the centre of his back. Young birds are similar to the adults, but have rufous fringes to the wing coverts and are paler below. The call is a squeaky ''sweek'', and the song is ''cheep cheep CHEEP CHEEP cheep''. The russet antshrike feeds on insects and other arthropods, which it gleans from foliage like a vireo. It may be seen alone, in pairs, or with tanagers and warblers in mixed-species feeding flocks == References == * Stiles and Skutch, ''A guide to the birds of Costa Rica'' ISBN 0-8014-9600-4 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「Russet antshrike」の詳細全文を読む スポンサード リンク
