The ruddy woodcreeper (''Dendrocincla homochroa''), is a passerine bird which breeds in the tropical New World from southern Mexico to northern Colombia and extreme northern Venezuela. This woodcreeper is typically long and weighs . It is almost entirely rufous, with a paler throat and grey line from the bill to the eye. The bill is longish and straight. The call is a squeaky ''quink'' or loud ''deeah''. The ruddy woodcreeper is found in premontane humid forest in lowlands and foothills up to ,〔 and also in adjacent semi-open woodland and clearings. Ruddy woodcreepers feed on spiders and insects. They will follow columns of army ants, sometimes in groups of up to three birds, dropping from saplings to catch prey fleeing the ants. It builds a leaf-lined nest up in a hollow palm tree stump, and lays 2–3 white eggs. Adult birds also sleep alone in tree crevices. Like other woodland birds, this species has been adversely affected by deforestation.〔 For example, in Colombia it is apparently common in the northwestern Sierra Nevada de Santa Marta, though otherwise a rather rare bird. This species apparently avoids human-altered habitat and secondary forest whenever possible. It is thus useful as a bioindicator.〔 Nonetheless, it occupies a large range and wherever sufficient habitat remains, it is often not particularly uncommon. The IUCN considers it a Species of Least Concern.〔 ==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「Ruddy woodcreeper」の詳細全文を読む スポンサード リンク
