Similar species

Very similar to Spot-tailed Antwren (especially male) but differs in larger size and voice.


Extreme south and southeast Colombia, eastern Ecuador and northeast Peru.
Formerly considered rare but found to have been overlooked in many areas. Uncommon to fairly common in its range.


This is a monotypic species.
It forms a superspecies with Spot-tailed Antwren and was formerly considered conspecific.


Found in the canopy and subcanopy of wet, lowland evergreen forest. Recorded at 100 to 600m but mainly below 450m.
Prefers vine tangles in terra firme forest and floodplain-forest.


Feeds on inscects, probably also on spiders.
Forages in pairs or family groups 20 to 40m above the ground, usually in mixed-species flocks.
Not much known about breeding. One nest found in Peru in July was a small pendent cup or bag made of green moss and stems of lichens. It was placed 35m above the ground in a fork of a thin branch.
Presumably a resident species.
