Further study resulted in Buarremon's being resurrected. Buarremon atricapillus was later reassigned as one of many subspecies of what was then the "stripe-headed brushfinch" (Buarremon torquatus). In 2008 taxonomists began merging Buarremon into Arremon. Following a study published in 2010 and some earlier studies, taxonomists began splitting the "stripe-headed brushfinch" into eight species, one of which was the black-headed brushfinch.

GBIF citizen-science records
It is estimated from how often the Black-headed Brushfinch is recorded against all the birds logged in Farallones de Cali National Natural Park (1,231 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.
