The rufous-sided crake (Laterallus melanophaius) is a species of bird in subfamily Rallinae of family Rallidae, the rails, gallinules, and coots. It is found in every mainland South American country except Chile. What is now the white-throated crake (L. albigularis) was for a time treated as a third subspecies.
The rufous-sided crake is 14 to 18 cm (5.5 to 7.1 in) long and weighs about 50 to 60 g (1.8 to 2.1 oz). The sexes are alike. Both subspecies' bills have a gray maxilla with a pea green cutting edge and a pale pea green mandible with a white tip. Their legs and feet are light gray brown to olive brown. The nominate subspecies has dark olive brown upperparts with a gray tinge around the eye. The face and sides of the breast are rufous to cinnamon rufous. The throat and center of the breast are white, the flanks and belly barred white and blackish brown, and the undertail coverts are dark cinnamon rufous. Subspecies L. m. oenops is similar to the nominate, but has paler upperparts and is rufous on the forecrown and around the eye. Wikipedia →

Rare
Under 5% of wildlife watchers report a Rufous-sided Crake sighting in Rio de Janeiro on a given day, based on 125 verified sightings from GBIF citizen-science data. It is the 117th most-seen of the 278 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
January
In that month about 10% of wildlife watchers report a Rufous-sided Crake in Rio de Janeiro on a given day, against under 5% in February to December, the lowest months. That is one of Rio de Janeiro's wettest months, with about 210 mm of rain against 40 mm in August.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Rufous-sided 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.
7th of 14
Of the 14 cities where we can rate Rufous-sided Crake sightings, Rio de Janeiro ranks 7th at under 5%. The best odds are in Buenos Aires (Argentina, about 10%), Porto Alegre (Brazil, about 10%) and Recife (Brazil, about 10%).
Same family: Rallidae

GBIF citizen-science records
It is estimated from how often the Rufous-sided Crake is recorded against all the birds logged in Rio de Janeiro (125 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.
