Ruddy Treerunner

This treerunner is found in hills and mountains from 1200 m up to the timberline, in forests and adjacent edges and clearings. It builds a large enclosed oval nest 25 m high in the crown of a tree on the underside of a thick branch. The nest is camouflaged with mosses and epiphytes and has a downward pointing entrance tunnel at its base. The eggs are undescribed, but members of this family typically lay two white eggs.

The Ruddy Treerunner is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.

The adult Ruddy Treerunner is 16 cm long, weighs 18 g and looks like a small, short-billed woodcreeper, but has soft, rather than rigid, tail spines. It has bright rufous upperparts and a white supercilium. It has a white throat and otherwise tawny underparts. Young birds are almost identical to the adults. The call is a sharp tsit, and the song is a twittering trill. More
