Small brown flycatcher found in humid forest from southern Peru to central Bolivia. Very plain; adults have a faint rusty tinge on the head, but this is lacking in young birds. Similar to juvenile Rufous-headed Pygmy-Tyrant, but lacks rusty wings and tail. It does not overlap with Bronze-olive Pygmy-Tyrant. Stays quite low in the understory; sometimes gives thin, high-pitched whistles and trills as well as soft snaps.
