The Fuscous Flycatcher is fairly widespread in South America east of the Andes from Colombia to north-east Argentina. There is a possibility that more than one species is involved. They are usually inconspicuous and prefer the undergrowth of woodland and forest borders. In the Amazon Basin they frequent river islands.
They tend to perch upright a bit like a Peewee or an Empidonax flycatcher. Note the long, conspicuous white supercilium and the two buff wing bars. These are most marked in the subspeciesC. f. bimaculatus shown in these photos but tend to be less distinct and bright in the Amazonian races. The bill is black with a pale base to the lower mandible.
The third photo shows this flycatcher on its nest in the stump of a broken branch.
