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 →

Rare
Under 5% of wildlife watchers report a Masked Water-Tyrant sighting in Machalilla National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 237th most-seen of the 248 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Masked Water-Tyrant is recorded against all the birds logged in Machalilla National Park (6 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.
