The yellow-lored tody-flycatcher, or gray-headed tody-flycatcher, (Todirostrum poliocephalum) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is endemic to Brazil. The yellow-lored tody-flycatcher was originally described by Prince Maximilian of Wied-Neuwied in 1831 as Todus poliocephalus. He called it "Der grauköpfige Plattschanbel" which roughly translates to "grey-headed flatbill". It was later moved to genus Triccus and still later to its current Todirostrum.
The yellow-lored tody-flycatcher is monotypic. The yellow-lored tody-flycatcher is 8.8 to 10.2 cm (3.5 to 4.0 in) long and weighs about 5 to 6 g (0.18 to 0.21 oz). The sexes have the same plumage. Adults have a slate-gray crown and nape, large lemon yellow or sulphur yellow patches on the lores with a black stripe below them, and greenish cheeks. Their back, rump, and uppertail coverts are "siskin-green" (Wied's term) or olive. Their wings are black-brown with yellow-green edges on the flight feathers and yellow or olive edges on the coverts; the last show as two wing bars. Their tail is dark grayish brown with olive-green edges on the feathers. Their... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Gray-headed Tody-Flycatcher is recorded against all the birds logged in Niterói (481 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.
