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".

Rare
Under 5% of wildlife watchers report a Russet-Crowned Crake sighting in Medellín on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 179th most-seen of the 244 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Russet-Crowned Crake in Medellín on a given day, so our monthly data shows no clear season.
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.
6th of 6
Of the 6 cities where we can rate Russet-Crowned Crake sightings, Medellín ranks 6th at under 5%. The best odds are in Goiânia (Brazil, about 10%), 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 Medellín (15 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.
