The masked water tyrant (Fluvicola nengeta) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Argentina, Brazil, Colombia, Ecuador, Peru, and as a vagrant to Uruguay and Paraguay. The masked water tyrant was formally described in 1766 as Lanius nengeta, erroneously placing it in the shrike family Laniidae. It is now placed in the genus Fluvicola that was introduced by the English naturalist William Swainson in 1827. The genus name is derived from a combination of Latin fluvius meaning "river" and -cola meaning "dweller". Some early twentieth century authors called it Fluvicola climazura.
Subspecies F. n. atripennis was formally described as a species and some early twenty-first century authors suggest that it again should be treated that way. The masked water tyrant shares genus Fluvicola with the pied water tyrant (F. pica) and the black-backed water tyrant (F. albiventer).
The masked water tyrant is 14.5 to 15 cm (5.7 to 5.9 in) long. The sexes have the same plumage. Adults... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Masked Water-Tyrant is recorded against all the birds logged in Niterói (176 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.
