Western Olivaceous Flatbill Rhynchocyclus aequinoctialis

A medium-sized flycatcher with a fairly long tail and rounded head. Dull brownish-olive overall with few distinctive features; look for indistinct pale eyering and very broad bill. Occurs singly or in pairs in the lower and middle levels of forests in lowlands and foothills, up to around 1,000 m. Often follows mixed-species flocks. Fairly widespread in western South America; occurs from eastern Panama to Bolivia and western Brazil. Listen for rising, accelerating series of urgent whistles.
