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 Curitiba on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 213th most-seen of the 247 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 Hangnest Tody-Tyrant in Curitiba on a given day, so our monthly data shows no clear season.
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 Curitiba, in our data
Curitiba is the only city 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 family: Tyrannidae
The closest relatives of the Hangnest Tody-Tyrant that you can see in Curitiba (family Tyrannidae, Tyrant Flycatchers) are Great Kiskadee (about 90%), Tropical Kingbird (about 30%) and Cattle Tyrant (about 20%), 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 Curitiba (10 verified sightings), 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.
