Johannes's tody-tyrant, or Joao's tody-tyrant, (Hemitriccus iohannis) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Bolivia, Brazil, Colombia, Ecuador, and Peru. Johannes's tody-tyrant has a complicated taxonomic history. It was originally described in 1907 as Euscarthmus iohannis. During different parts of the twentieth century it was treated as a subspecies of the stripe-necked tody-tyrant (now H. striaticollis) and as a full species in genera Euscarthmornis and Idioptilon. Those two genera were eventually merged into Hemitriccus.
Johannes's tody-tyrant is monotypic. Johannes's tody-tyrant is about 11 cm (4.3 in) long and weighs 9.2 to 12.7 g (0.32 to 0.45 oz). The sexes have the same plumage. Adults have a bright olive crown. They have brownish lores, sometimes with a white spot above them, and the color extends around the eye. Their back and rump are bright olive. Their wings are dusky olive with indistinct yellow edges on the flight feathers and indistinct yellow tips on the coverts; the latter show as two wing bars. Their tail is bright olive. Their throat is whitish with very thin black... Wikipedia →

Rare
Under 5% of wildlife watchers report a Johannes's Tody-Tyrant sighting in Tambopata National Reserve on a given day, based on 27 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 435th most-seen of the 550 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Johannes's Tody-Tyrant in Tambopata National Reserve on a given day, so our monthly data shows no clear season.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Johannes's 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.
2nd of 2
Of the 2 parks where we can rate Johannes's Tody-Tyrant sightings, Tambopata National Reserve ranks 2nd at under 5%. The best odds are in Manu National Park (Peru, about 10%).
GBIF citizen-science records
It is estimated from how often the Johannes's Tody-Tyrant is recorded against all the birds logged in Tambopata National Reserve (27 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.
