The grey-headed tanager (Eucometis penicillata) is a species of bird in the family Thraupidae, the tanagers and allies. It is found in Mexico, every Central American country except El Salvador, and every mainland South American country except Argentina, Chile, French Guiana, and Uruguay.
The grey-headed tanager was formally described in 1825 by the German naturalist Johann Baptist von Spix under the binomial name Tanagra penicillata. Spix did not specify a type locality but this was later designated as Fonte Boa in the Brazilian state of Amazonas. The grey-headed tanager is now the only species in the genus Eucometis that was introduced by the English zoologist Philip Sclater in 1856. The genus name is derived from Ancient Greek eukomēs meaning "with lovely hair". The specific epithet penicillata is from the Latin diminutive of peniculus meaning "brush".
Within the Thraupidae the grey-headed tanager is a member of the subfamily Tachyphoninae and is the sister species to the black-goggled tanager (Trichothraupis melanops). The grey-headed tanager has these seven subspecies Wikipedia →

GBIF citizen-science records
It is estimated from how often the Gray-headed Tanager is recorded against all the birds logged in Tikal National Park (348 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.
