At the rump and the upper tail-coverts the coloring goes over to the reddish brown or cinnamon-colored and on the upper wing-coverts she is lively olive - brown to reddish -yellow brown. The inner webs of the middle wing-coverts are mostly dull dark brown. The seams of the outer webs of ceilings and most of the outer webs of the great coverts are reddish -yellow brown. The hand and arm swing are brownish with a lively brown hem on the outer webs, which is increasingly becoming wider towards the secondaries. The shield springs are completely reddish brown. The under wing-coverts are reddish - orange, with the large ceiling are a bit brighter. The underside of the primaries is easy cinnamon on the hem of the inner webs.

Vocalizations
The song is distinctive and is played usually in the form of a duet. He sounds like a long rattling rattling, which consists of short, loud sounds that are of a bird (presumably the male ) is reproduced. In different periods, a second bird joins in with the singing, which is rough, even shorter sounds. Then volume and speed gradually decrease until the vocals, which is still audible at a considerable distance, is usually terminated with a solo of the first singing bird. When the birds are excited to take the duets from in speed. Then they give way to a series of slower dual or Dreichfachtönen that go on in different periods before they are accelerated in another duet. The duets are easily distinguished from those of the Strichelkehlcanasteros ( Thripophaga cherriei ) and the Zimtschwanzcanasteros ( Thripophaga macroura ).
