Such's Antthrush Chamaeza meruloides

Plump anthrush with a short cocked-tail and long legs. Walks quietly on the ground of humid montane forests between 200 and 1500 m, where it is usually very difficult to see. It has a rufous crown, olive-brown back, and a heavily streaked belly. Note the white throat and eyebrow. Almost identical in plumage to Rufous-tailed Antthrush, but differs in song. Such's Antthrush sings a long (20-40 seconds) and melodious series of “tju tju tju” notes while Rufous-tailed Antthrush has a faster and shorter (3-4 seconds) song.
