The white-eyed tody-tyrant (Hemitriccus zosterops) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela. The species had a complicated taxonomic history from its original description to late in the twentieth century. It was described as Euscarthmus zosterops. It was later moved to genus Idioptilon, and later still both Euscarthmus and Idioptilon were merged into Hemitriccus. In the early twentieth century some authors treated what is now the white-eyed tody-tyrant as a subspecies of the stripe-necked tody-tyrant (H. striaticollis). And what is now the white-bellied tody-tyrant (H. griseipectus) was for a time treated as conspecific with the white-eyed.
The white-eyed tody-tyrant is about 11 cm (4.3 in) long and weighs 7.8 to 10 g (0.28 to 0.35 oz). The sexes have the same plumage. Adults of the nominate subspecies have an olive-green crown and nape. They have a whitish spot above the lores and... Wikipedia →

Rare
Under 5% of wildlife watchers report a White-eyed Tody-Tyrant sighting in Anavilhanas National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 219th most-seen of the 291 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
January, March and June
In those months about 10% of wildlife watchers report a White-eyed Tody-Tyrant in Anavilhanas National Park on a given day, against under 5% in February, April–May and July–December, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most White-eyed Tody-Tyrant sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 parks where we can rate White-eyed Tody-Tyrant sightings, Anavilhanas National Park ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Brownsberg Nature Park (Suriname, under 5%).
GBIF citizen-science records
It is estimated from how often the White-eyed Tody-Tyrant is recorded against all the birds logged in Anavilhanas National Park (10 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.
