Brazil, Colombia and Ecuador

The Dusky-capped Flycatcher is distributed from south-west USA, through Central America and into South America as far south as northern Argentina. It is lacking from a good part of central and eastern Brazil but there is a disjunct population in south-east Brazil where photos 1 to 3 were taken. Photos 4 and 5 are from central Colombia. See the distribution map at xeno-canto.

It is a small Myiarchus with a bushy crest and a brownish-black crown contrasting with dull, dark olive upperparts as can be seen in the 2nd photo. This also shows the dull whitish edges to the wing coverts and the hint of rufous on the edge of the primaries. The tail is dark brown with no rufous edging.

It has two small, horny swellings at the bend of each wing, totally useless for field identification but useful for providing the specific name derived from tuberculum, Latin for a small bump or swelling.
