The yellow-olive flatbill or yellow-olive flycatcher (Tolmomyias sulphurescens) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Mexico, in every Central American country, on Trinidad, and in every mainland South American country except Chile.
The yellow-olive flatbill has these 16 subspecies: Since the late twentieth century several authors have suggested that what is now considered a single species is actually several species, perhaps as many as 12. Some authors consider several of the South American subspecies to be "dubious".
The yellow-olive flatbill is 12.5 to 14 cm (4.9 to 5.5 in) long and weighs 14.5 to 15.2 g (0.51 to 0.54 oz). The sexes have the same plumage.

Their upperparts are olive-green. Their wings are dusky... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Yellow-olive Flycatcher is recorded against all the birds logged in Curitiba (9 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.
