The russet-crowned crake (Rufirallus viridis) is a species of bird in subfamily Rallinae of family Rallidae, the rails, gallinules, and coots. It is found in Bolivia, Brazil, Colombia, Ecuador, the Guianas, Paraguay, Peru, and Venezuela.
The russet-crowned crake was formally described in 1776 by the German zoologist Philipp Statius Müller under the binomial name Rallus viridis. Müller based his account on a plate of the "Râle de Cayenne" that had been published to accompany the Comte de Buffon's Histoire Naturelle des Oiseaux. The russet-crowned crake is now placed in the genus Rufirallus that was introduced in 1856 by the French naturalist Charles Lucien Bonaparte. The genus name combines the Latin rufus meaning "rufous" with the genus Rallus that had been introduced by Carl Linnaeus in 1758 for the rails. The specific epithet viridis is Latin meaning "green".

With luck
About 10% of wildlife watchers report a Russet-Crowned Crake sighting in Goiânia on a given day, based on 38 verified sightings from GBIF citizen-science data. It is the 100th most-seen of the 174 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
March
In that month about 20% of wildlife watchers report a Russet-Crowned Crake in Goiânia on a given day, against under 5% in January–February and July–August, the lowest months. That is one of Goiânia's wettest months, with about 210 mm of rain against almost none in July.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Russet-Crowned Crake sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 6 cities where we can rate Russet-Crowned Crake sightings, Goiânia has the highest daily chance: about 10%. Next come Belém (Brazil, under 5%) and Rio de Janeiro (Brazil, under 5%).
GBIF citizen-science records
It is estimated from how often the Russet-Crowned Crake is recorded against all the birds logged in Goiânia (38 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.
