The rufous-rumped antwren (Euchrepomis callinota) is a species of bird in subfamily Euchrepomidinae of family Thamnophilidae, the "typical antbirds". It is found in Colombia, Costa Rica, Ecuador, French Guiana, Guyana, Panama, Peru, Suriname, and Venezuela.
The rufous-rumped antwren was described by the English zoologist Philip Sclater in 1855 and given the binomial name Formicivora callinota. It was transferred to genus Terenura in 1885. There it remained until the current genus Euchrepomis was created in 2012 following phylogenetic analysis.
The rufous-rumped antwren has these four subspecies: Euchrepomis callinota callinota (Sclater, PL, 1855) Euchrepomis callinota peruviana (Meyer de Schauensee, 1945) Euchrepomis callinota venezuelana (Phelps, WH & Phelps, WH Jr, 1954)
Euchrepomis callinota guianensis (Blake, 1949) The rufous-rumped antwren is 10 to 12 cm (3.9 to 4.7 in) long and weighs about 7 to 9.5 g (0.25 to 0.34 oz).

Adult males of the nominate subspecies E. c. callinota have blackish lores and line... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Rufous-rumped Antwren is recorded against all the birds logged in Brownsberg Nature Park (5 verified sightings from 2019 to 2026), 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.
