The Chaco chachalaca (Ortalis canicollis) is a species of bird in the family Cracidae, the chachalacas, guans, and curassows. It is found in Argentina, Bolivia, Brazil, Paraguay, and possibly Uruguay. The latter might actually be a subspecies of plain chachalaca (O. vetula) or a species in its own right. The Paraguayan population has been treated as a separate subspecies but that status has not been generally accepted.
The Chaco chachalaca is 50 to 56 cm (1.6 to 1.8 ft) long and weighs 479 to 678 g (1.1 to 1.5 lb). The nominate subspecies' head, back, and breast are gray and the belly tan to brown. It has bare pinkish red skin around the eye. O. c. pantanalensis is browner and the facial skin is more purplish than pinkish.
The nominate subspecies of Chaco chachalaca is found in the Gran Chaco of eastern Bolivia, western Paraguay, and northern Argentina. O. c. pantanalensis is found in southwestern Mato Grosso and Mato Grosso do Sul of Brazil... Wikipedia →

No species of the same family or order lives in El Impenetrable National Park, so these are its closest relatives here: other birds.
Very likely
About 80% of wildlife watchers report a Chaco Chachalaca sighting in El Impenetrable National Park on a given day, based on 390 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the most-seen of the 219 birds we can rate there. Over three days the chance rises to over 90%, if each day is a fresh chance.
July and September–October
In those months about 90% of wildlife watchers report a Chaco Chachalaca in El Impenetrable National Park on a given day, against about 50% in January and February, the lowest months. Those are among El Impenetrable National Park's driest months, with about 50 mm of rain a month against 120 mm in March. December has too few records to rate.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Chaco Chachalaca sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 parks where we can rate Chaco Chachalaca sightings, El Impenetrable National Park has the highest daily chance: about 80%. Next come Parque Estadual Encontro das Águas (Brazil, about 70%) and Iberá National Park (Argentina, under 5%).
GBIF citizen-science records
It is estimated from how often the Chaco Chachalaca is recorded against all the birds logged in El Impenetrable National Park (390 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.
