The ash-winged antwren is a species of bird in subfamily Euchrepomidinae of family Thamnophilidae, the "typical antbirds". It is found in Brazil, Colombia, Ecuador, French Guiana, Guyana, Suriname, Venezuela, and possibly Peru.
Region
Northern Amazon Basin and the Guianas
Typical Environment
Occurs across lowland tropical forests of Brazil north of the Amazon, southern Venezuela, eastern Colombia and Ecuador, and the Guianas; it possibly reaches adjacent northern Peru. It inhabits terra firme forest, edges, and secondary growth, and also uses white-sand (campinarana) forest where available. Birds forage mostly in the lower to mid understory, often between 1–8 m above ground. It is generally uncommon to fairly common but easily overlooked due to its secretive habits.

Formerly placed in the genus Terenura, the ash-winged antwren was reassigned to Euchrepomis after molecular studies clarified relationships within antbirds. It is a quiet, understory insectivore that often joins mixed-species flocks, making it easier to detect by its high, thin song than by sight. Subtle sexual dimorphism means males show stronger gray wing panels, while females are warmer and duller.
Temperament
skulking yet active in dense understory
Flight Pattern
short rapid wingbeats over brief distances
Social Behavior
Usually found in pairs or small family groups and regularly associates with mixed-species flocks moving through the understory. Nesting is presumed to involve a small cup placed low in vegetation, with both sexes participating in care. Territorial songs and contact calls help pairs remain in touch within dense cover.
Migratory Pattern
Resident
Song Description
Song is a short, high-pitched series of thin notes that accelerates slightly, often given from concealed perches. Calls include sharp, sibilant chips and soft trills that can be hard to localize.
