Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

The Plain-winged Antwren faces severe pressure from rapid deforestation throughout its restricted Amazonian range, particularly in Colombia and Venezuela where agricultural expansion and cattle ranching have fragmented its lowland forest habitat. Mining activities and infrastructure development further threaten remaining forest patches, while the species' specialized foraging behavior in mixed-species flocks makes it particularly vulnerable to habitat fragmentation that disrupts these critical social feeding associations.

Threat summary

Habitat

The Plain-winged Antwren inhabits lowland tropical rainforests and humid forest edges in the Amazon Basin, typically found in the understory and middle canopy levels. It prefers primary and mature secondary forests with dense vegetation structure that supports the mixed-species foraging flocks it depends on for feeding.
