The curl-crested jay (Cyanocorax cristatellus) is a species of jay native to South America. This New World jay is a beautiful and large (35 cm/14 in overall) bird with predominantly dark blue back, an almost black head and neck, and snow-white chest and underparts. They have a pronounced curled crest rising from just behind the beak; the crest is on average larger in males, but the sexes are generally quite similar.
The voice is a loud, gray, graa, gray-gray-gray, sometimes repeated 8-10 times. They sound similar to crow. Curl-crested jays are native to the cerrados of central and southern and the caatinga of north-eastern Brazil. In the southeast Amazon Basin, curl-crested jay ranges into the upstream headwater regions adjacent to the northwestern cerrado. In the west, the extreme headwaters of the west-flowing Guaporé River on the Brazil-Bolivia are home. For the southeast Amazon, the north-flowing rivers that limit the range are the Tapajós on the west, the Xingu River, then the adjacent drainage to the east, the Araguaia-Tocantins River system. The range continues easterly and southerly through the cerrado. The range on the river systems is only the upstream half of the drainages. They can also be found in extreme northern Paraguay. Altogether, they are limited by the extent of habitat, but wherever this is suitable, they may not be rare. For example, they are the most commonly seen corvid in the Serra do Cipó National Park.
They live in groups of from 6 to 12 individuals, moving from food source to food source during the day. They leave a lookout nearby to keep watch for predators. This bird is a generalist, eating almost anything, including eggs and nestlings of other birds, insects, arthropods, and small vertebrates like geckos. It also likes palm nuts and is particularly fond of the seeds of the native Inga laurina and the fruits of the introduced umbrella tree (Heptapleurum actinophyllum). Curl-crested jays have even been observed spending the early morning in a pequi tree (Caryocar brasiliense) where they fed on nectar, and perhaps also on invertebrates which had visited the mainly night-blooming flowers of this plant.
This jay is not considered a threatened species by the IUCN, and in fact they are at present expanding their range. However, range expansions may only be temporary and populations may eventually disappear from formerly settled locations again. Wikipedia →

With luck
About 10% of wildlife watchers report a Curl-crested Jay sighting in Itatiaia National Park on a given day, based on 213 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 152nd most-seen of the 352 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
May
In that month about 50% of wildlife watchers report a Curl-crested Jay in Itatiaia National Park on a given day, against under 5% in February, July, September and November, the lowest months. That is one of Itatiaia National Park's driest months, with about 70 mm of rain against 330 mm in December.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Curl-crested Jay sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 6
Of the 6 parks where we can rate Curl-crested Jay sightings, Itatiaia National Park ranks 3rd at about 10%. The best odds are in Emas National Park (Brazil, about 80%) and Serra da Canastra National Park (Brazil, about 20%).
Same order: Passeriformes
The closest relatives of the Curl-crested Jay that you can see in Itatiaia National Park (order Passeriformes, Perching Birds) are Rufous-collared Sparrow (about 80%), Golden-crowned Warbler (about 70%) and Saffron Finch (about 60%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Curl-crested Jay is recorded against all the birds logged in Itatiaia National Park (213 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.
