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 Amboró National Park on a given day, based on 30 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 113th most-seen of the 273 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May
In that month about 20% of wildlife watchers report a Euler's Flycatcher in Amboró National Park on a given day, against under 5% in July–August and November–April, the lowest months. June has too few records to rate.
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.
5th of 17
Of the 17 parks where we can rate Euler's Flycatcher sightings, Amboró National Park ranks 5th at about 10%. The best odds are in Serra dos Órgãos National Park (Brazil, about 40%), Itatiaia National Park (Brazil, about 20%) and El Palmar National Park (Argentina, about 10%).
Same family: Tyrannidae
The closest relatives of the Euler's Flycatcher that you can see in Amboró National Park (family Tyrannidae, Tyrant Flycatchers) are Black Phoebe (about 60%), Yellow-olive Flycatcher (about 40%) and Sepia-capped Flycatcher (about 30%), 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 Amboró National Park (30 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.
