The East Brazilian chachalaca (Ortalis araucuan) is a species of bird in the family Cracidae, the chachalacas, guans, and curassows. It is endemic to eastern Brazil. The East Brazilian chachalaca was considered a subspecies of the speckled chachalaca (Ortalis guttata). It has also been treated as conspecific with little chachalaca (O. motmot) and buff-browed chachalaca (O. superciliaris). It is monotypic.
The East Brazilian chachalaca is about 50 cm (1.6 ft) long. It has a dull rufous crown and nape, brown upperparts, and a reddish rump. Its gular patch is red. The lower throat and breast are dark brownish with whitish (female) or buffy (male) spots; the rest of the underparts are white except for the ochre vent. Its dark brown eye is surrounded by bare slate blue skin.
The East Brazilian chachalaca is found in a fairly narrow strip of far eastern Brazil, from Rio Grande do Norte south into Espírito Santo and Minas Gerais. Its primary habitat is the Atlantic Forest but also includes secondary forest, caatinga, and restinga landscapes.

Possible
About 30% of wildlife watchers report an East Brazilian Chachalaca sighting in Chapada Diamantina National Park on a given day, based on 201 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 40th most-seen of the 271 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
March, May and October
In those months about 40% of wildlife watchers report an East Brazilian Chachalaca in Chapada Diamantina National Park on a given day, against about 20% in April, August and December, the lowest months.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most East Brazilian Chachalaca sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Chapada Diamantina National Park, in our data
Chapada Diamantina National Park is the only park on Wallace's Line with enough records to rate East Brazilian Chachalaca sightings: about 30% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the East Brazilian Chachalaca is recorded against all the birds logged in Chapada Diamantina National Park (201 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.
