The buff-breasted wren (Cantorchilus leucotis) is a species of bird in the family Troglodytidae. It is found in the Amazon Basin of northern Brazil and Amazonian Colombia, Ecuador, Peru and northern-border Bolivia, and also the Guianan countries of Guyana, Suriname, and French Guiana.

There is considerable variation in plumage across the species' wide range. Adults' head, nape, shoulders, tail, and back are rufescent to grayish brown; the tail is heavily barred.

GBIF citizen-science records
It is estimated from how often the Buff-breasted Wren is recorded against all the birds logged in Manaus (50 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
