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 →

Rare
Under 5% of wildlife watchers report a Euler's Flycatcher sighting in Belo Horizonte on a given day, based on 39 verified sightings from GBIF citizen-science data. It is the 122nd most-seen of the 220 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.
April
In that month about 10% of wildlife watchers report a Euler's Flycatcher in Belo Horizonte on a given day, against under 5% in May to March, the lowest months. That is one of Belo Horizonte's driest months, with about 55 mm of rain against 270 mm in December.
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.
2nd of 10
Of the 10 cities where we can rate Euler's Flycatcher sightings, Belo Horizonte ranks 2nd at under 5%. The best odds are in Curitiba (Brazil, about 10%).
Same family: Tyrannidae
The closest relatives of the Euler's Flycatcher that you can see in Belo Horizonte (family Tyrannidae, Tyrant Flycatchers) are Great Kiskadee (about 90%), Tropical Kingbird (about 50%) and Boat-billed Flycatcher (about 40%), 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 Belo Horizonte (39 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.
