The chestnut-headed crake (Anurolimnas castaneiceps) is a species of bird in subfamily Rallinae of family Rallidae, the rails, gallinules, and coots. It is the only species placed in the genus Anurolimnas. It is found in Bolivia, Brazil, Colombia, Ecuador, and Peru.
The chestnut-headed crake was formally described in 1869 by the English ornithologists Philip Sclater and Osbert Salvin based on a specimen that had been collected in the Napo River region of eastern Ecuador. They coined the binomial name Porzana castaneiceps. The taxonomy of the chestnut-headed crake was previously uncertain and the species was placed in either Rufirallus or Anurolimnas. A molecular phylogenetic study published in 2023 found the chestnut-headed crake formed a basal branch within the Pardirallini clade (genera Mustelirallus, Pardirallus, Amaurolimnas and Aramides) with a date of divergence from the rest of the Pardirallini estimated at 15.4 to 18.5 Mya. Based on this result the chestnut-headed crake is now the only species placed in the genus Anurolimnas had been introduced in 1893 by the English ornithologist Richard Bowdler Sharpe. The genus name Anurolimnas combines the... Wikipedia →

Rare
Under 5% of wildlife watchers report a Chestnut-headed Crake sighting in Yasuní National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 515th most-seen of the 533 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 Chestnut-headed Crake in Yasuní National Park on a given day, so our monthly data shows no clear season.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Chestnut-headed 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.
Among the best
Of the 4 parks where we can rate Chestnut-headed Crake sightings, Yasuní National Park ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Sierra de la Macarena National Park (Colombia, under 5%), Tambopata National Reserve (Peru, under 5%) and Manu National Park (Peru, under 5%).
GBIF citizen-science records
It is estimated from how often the Chestnut-headed Crake is recorded against all the birds logged in Yasuní National Park (8 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.
