The ash-throated crake (Mustelirallus albicollis) is a species of bird in the subfamily Rallinae of the rail, crake, and coot family Rallidae. It is found in every mainland South American country except Chile. The taxonomy of genus Mustelirallus and that of the ash-throated crake in particular have not been settled. The International Ornithological Committee (IOC), the South American Classification Committee of the American Ornithological Society (SACC), and the Clements taxonomy moved the species from genus Porzana in 2015. The SACC and Clements also moved the Colombian crake and paint-billed crake from genus Neocrex to Mustelirallus while the IOC retains them in Neocrex. In addition, BirdLife International's Handbook of the Birds of the World (HBW) retains the ash-throated crake in Porzana and the other two in Neocrex.
This article uses the IOC/SACC/Clements genus. The SACC does not include subspecies in its published list. The ash-throated crake is 21 to 24 cm (8.3 to 9.4 in) long and weighs 90 to 120 g... Wikipedia →

Rare
Under 5% of wildlife watchers report an Ash-throated Crake sighting in Chapada dos Guimarães National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 240th most-seen of the 273 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.
November to January
In those months about 10% of wildlife watchers report an Ash-throated Crake in Chapada dos Guimarães National Park on a given day, against under 5% in May to October, the lowest months. Those are among Chapada dos Guimarães National Park's wettest months, with about 200 mm of rain a month against almost none in July. February to April have too few records to rate.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Ash-throated 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 9
Of the 9 parks where we can rate Ash-throated Crake sightings, Chapada dos Guimarães National Park ranks 7th at under 5%. The best odds are in Iberá National Park (Argentina, about 10%), Emas National Park (Brazil, about 10%) and Serra dos Órgãos National Park (Brazil, under 5%).
GBIF citizen-science records
It is estimated from how often the Ash-throated Crake is recorded against all the birds logged in Chapada dos Guimarães National Park (7 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.
