The chestnut-capped brushfinch (Arremon brunneinucha) is a species of bird in the family Passerellidae, the New World sparrows. It is found from Mexico to Peru. The chestnut-capped brushfinch was formally described in 1839 with the binomial Embernagra brunnei-nucha. It eventually was reassigned to genus Buarremon and the specific epithet revised to brunneinuchus. Genus Buarremon was still later merged into genus Atlapetes but further study resulted in Buarremon's being resurrected. In 2000 taxonomists again revised the specific epithet to its current brunneinucha. In 2008 taxonomists began merging Buarremon into Arremon.
The chestnut-capped brushfinch's further taxonomy is unsettled. The IOC, AviList, and BirdLife International's Handbook of the Birds of the World assign it these nine subspecies: Clements also sets A. b. apertus apart within the species, calling it the "chestnut-capped brushfinch (plain-breasted)". Clements groups the others as the "chestnut-capped brushfinch (chestnut-capped)".

GBIF citizen-science records
It is estimated from how often the Chestnut-capped Brushfinch is recorded against all the birds logged in Medellín (58 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.
