Typical Environment
Occurs in the lowland forests of Bolivia, Brazil, Colombia, and Peru, especially along major rivers. It favors river-edge thickets, seasonally flooded várzea, young secondary growth, and gallery forest. Frequently uses dense vine tangles, Cecropia stands, and shrubbery on river islands and oxbow lakes. It is most common in the understory from near ground level to a few meters up, occasionally along terra firme edges.

The leaden antwren is a tiny Amazonian antbird whose sexes look very different: males are plain slate-gray while females are warm brownish with buffy tones. It often joins mixed-species flocks in the understory and edges of lowland forests. Although it belongs to the antbird family, it is not an obligate army-ant follower and mostly gleans small arthropods from foliage.
Temperament
active and skulking
Flight Pattern
short rapid wingbeats
Social Behavior
Usually seen in pairs or small family groups moving quickly through dense understory. Regularly joins mixed-species foraging flocks along forest edges and riverine thickets. Nests are small cups placed low in dense vegetation; both parents are involved in incubation and care.
Migratory Pattern
Resident
Song Description
Song is a thin, high-pitched series of whistles or trills that may accelerate slightly, delivered from low perches in dense cover. Calls include sharp chips and soft, sibilant notes used to keep contact with a mate.
