Tiny flycatcher; common and widespread, but heard far more often than seen. When seen well, note pale eye and elongated crown feathers, giving this bird a hammer-headed appearance. Found in humid forest understory and second-growth as well as in savanna woodland. Frequently found near gaps and vine tangles where it sits quietly, then sallies upward to glean insects from leaves. Song is an irregular series of ticking notes that sometimes runs into a trill, often given for long periods throughout the day. Similar to Double-banded Pygmy-Tyrant, but vocalizations are less buzzy.
