This small bird inhabits wooded areas near water in northern South America. A 2000 study treated the forms now matched to CoL ID 3PP56 as caudata and intermedia, and compared their plumage and ranges.
In both studied forms, the crown is slightly grayer than the olive-brown back, with a whitish chin, brighter yellow belly, pale tail tips and whitish wing-bars. The throat and breast are buff to ochraceous: deeper in caudata and paler in intermedia.
The study reports an affinity for wooded places near water and birds usually encountered alone or in pairs in lower to middle forest layers. They glean arthropods from live foliage. The caudata form is associated mainly with Orinoco várzea and, in the Guianas, mostly mangroves.
