It is found in the Amazon Basin of northern Brazil and Amazonian Colombia, Ecuador, Peru and northern-border Bolivia; also the Guianan countries Guyana, Suriname, French Guiana. It occurs in non-Amazonian regions of Venezuela and Colombia and its range extends into eastern Panama.


Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical mangrove forests, subtropical or tropical swamps, and heavily degraded former forest. It is found in forest undergrowth and thickets near water and is more often heard than seen. It lives in pairs, seeking insects in the tangled vegetation along riverbanks, forests and clearings that have partly regrown.


Build a globular nest with the entrance near the top. Clutch size is 2-3 eggs. Young (1-3) often remain with their parents until the latter’s next breeding attempts.

Feeding habits

Buff-breasted Wrens forage mostly in the understory, gleaning arthropods from upper and lower leaf surfaces, dry branches, and aerial litter.


This species has a large range, with an estimated global extent of occurrence of 8,600,000 km². The global population size has not been quantified, but it is believed to be large as the species is described as ‘common’ in at least parts of its range (Stotz et al. 1996). Global population trends have not been quantified, but the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e., declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern.
