An unmistakable, dainty woodland flycatcher with a slightly peaked head shape. It has a gray head and upper breast with a narrow white eye-ring. Upperparts are olive-green; breast and belly are bright yellow. An active member of mixed-species foraging flocks, but also seen singly or in pairs. Quite vocal, with a loud, squeaky five-noted song delivered throughout the year. Contact and alarm calls include sharp “chilup,” “kitwik,” or “chit” notes repeated a few times.
