The grey-eyed greenlet is monotypic. The grey-eyed greenlet is 12.5 to 13 cm (4.9 to 5.1 in) long. The sexes have the same plumage.

Their nape and upper back are dull gray-brown and their lower back, shoulders, and rump are green-tinged gray-brown.

Their chin is dull whitish, their throat dull grayish, their flanks... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Gray-eyed Greenlet is recorded against all the birds logged in Chapada Diamantina National Park (30 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.
