Euler's flycatcher (Lathrotriccus euleri) is a small passerine bird in the family Tyrannidae, the tyrant flycatchers. It is found on Trinidad and in every mainland South American country except Chile. It formerly was found on Grenada.
Euler's flycatcher has a complicated taxonomic history. Subspecies L. e. flaviventris was originally described as Blaccicus flaviventris. Subspecies L. e. lawrencei was originally described as Ochthaeca flaviventris but later renamed Empidonax lawrencei. In the early 1900s genus Empidochanes was merged into Empidonax. Wikipedia →

With luck
About 10% of wildlife watchers report a Euler's Flycatcher sighting in Curitiba on a given day, based on 75 verified sightings from GBIF citizen-science data. It is the 109th most-seen of the 247 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
March
In that month about 20% of wildlife watchers report a Euler's Flycatcher in Curitiba on a given day, against under 5% in February, April–August and November, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Euler's Flycatcher sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 10 cities where we can rate Euler's Flycatcher sightings, Curitiba has the highest daily chance: about 10%. Next come Belo Horizonte (Brazil, under 5%) and São Paulo (Brazil, under 5%).
Same family: Tyrannidae
The closest relatives of the Euler's Flycatcher 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 Euler's Flycatcher is recorded against all the birds logged in Curitiba (75 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.
