The Curl-crested Jay (Cyanocorax cristatellus) is a jay from South America.
This New World or "blue" 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 a crow.
Curl-crested Jays are almost Brazilian endemic. They are native to the Cerrado of central and southern and the Caatinga of northeastern Brazil. They can also be found in extreme northern Paraguay. (from Wikipedia)
They are known in Brazil as "gralha-do-campo".
