The golden-faced tyrannulet (Zimmerius chrysops) is a species of bird in the tyrant flycatcher family Tyrannidae. It is found in Colombia, Ecuador, Peru, and Venezuela. The golden-faced tyrannulet was formally described in 1859 as Tyrannulus chrysops by the English zoologist Philip Sclater based on specimens collected by the zoologist Louis Fraser in Gualaquiza and Zamora of Ecuador. The specific epithet combines the Ancient Greek χρυσος/khrusos meaning "gold" with ωψ/ōps, ωπος/ōpos meaning "face". The type locality has been restricted to Zamora. The golden-faced tyrannulet is now one of 13 species placed in the genus Zimmerius that was introduced in 1977 by the American ornithologist Melvin Alvah Traylor Jr. with the golden-faced tyrannulet as the type species. The golden-faced tyrannulet was formerly considered to be conspecific with the Peruvian tyrannulet (Zimmerius viridiflavus).

Rare
Under 5% of wildlife watchers report a Golden-faced Tyrannulet sighting in Sierra de la Macarena National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 306th most-seen of the 418 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
March
In that month about 10% of wildlife watchers report a Golden-faced Tyrannulet in Sierra de la Macarena National Park on a given day, against under 5% in April to February, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Golden-faced Tyrannulet sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 6
Of the 6 parks where we can rate Golden-faced Tyrannulet sightings, Sierra de la Macarena National Park ranks 6th at under 5%. The best odds are in Farallones de Cali National Natural Park (Colombia, about 50%), Los Nevados National Natural Park (Colombia, about 10%) and Yasuní National Park (Ecuador, about 10%).
GBIF citizen-science records
It is estimated from how often the Golden-faced Tyrannulet is recorded against all the birds logged in Sierra de la Macarena National Park (15 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.
