Elusive, chunky brown bird of shady forest understory in humid tropical lowlands. Heard far more often than seen. Haunting, slurred whistle carries well and is easily imitated. Song given irregularly; not steadily repeated. Note the chunky build, drab dark olive-brown plumage with paler eyering accentuating big eye, and rather slender black bill. Tends to perch quietly and upright, then slips off like a ghost and not seen again.
