Appearance
The red-faced spinetail measures 15 cm long. The bird is named for its distinctive rufous cheeks and crown. The wings are also rufous. The back and nape are dark olive-brown, while the rest of the underparts are light olive-brown.
Behavior
This species often associates with mixed-species flocks.The red-faced spinetail places bits of grass and other material loosely streaming both above and below the nest chamber to break the shape of the nest and to cause it to resemble random debris without any underlying structure. This is considered as a case of protection of its nest from predators by camouflage or "masquerade".
