The hangnest tody-tyrant (Hemitriccus nidipendulus) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is endemic to Brazil. The hangnest tody-tyrant has a complicated taxonomic history. It was originally described in 1831 as Euscarthmornis nidipendulus and was the type specimen for genus Euscarthmornis. In part of the twentieth century it was assigned to genus Idioptilon. Both Euscarthmornis and Idioptilon were eventually merged into Hemitriccus.
The hangnest tody-tyrant is 9.5 to 10 cm (3.7 to 3.9 in) long and weighs 7.2 to 8 g (0.25 to 0.28 oz). The sexes have the same plumage. Adults of the nominate subspecies have a bright olive-green crown. Their lores are yellowish olive and the rest of their face bright olive-green. Their back and rump are bright olive-green. Their wings are olive with yellow edges on the flight feathers and coverts. Their tail is olive. Their throat and underparts are mostly white with faint grayish olive streaks on the breast and flanks. Wikipedia →

Rare
Under 5% of wildlife watchers report a Hangnest Tody-Tyrant sighting in Itatiaia National Park on a given day, based on 47 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 235th most-seen of the 352 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.
June and July
In those months about 10% of wildlife watchers report a Hangnest Tody-Tyrant in Itatiaia National Park on a given day, against under 5% in August to May, the lowest months. Those are among Itatiaia National Park's driest months, with about 35 mm of rain a month against 330 mm in December.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Hangnest 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.
Only Itatiaia National Park, in our data
Itatiaia National Park is the only park on Wallace's Line with enough records to rate Hangnest Tody-Tyrant sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Hemitriccus
The closest relatives of the Hangnest Tody-Tyrant that you can see in Itatiaia National Park (genus Hemitriccus, Tody-Tyrants and Bamboo-Tyrants) are Fork-tailed Pygmy-Tyrant (about 10%), Brown-breasted Pygmy-Tyrant (about 10%) and Drab-breasted Pygmy-Tyrant (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hangnest Tody-Tyrant is recorded against all the birds logged in Itatiaia National Park (47 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.
