This ovenbird is recorded from thorny woods and open woodland in northern Argentina. It has dull olive-brown upperparts, with chestnut on the forehead and part of the wing. An old account describes a large twig-and-thorn nest placed in a tree branch.
The upperparts are dull olive-brown; the forehead and lesser wing-coverts are chestnut, the tail is light chestnut, and the flanks are ochre against dirty-white underparts.
The book records the bird in thorny woods and open woodland. It describes a large mass of twigs and thorns placed in branches, quoting Barrows for the nest account.
