Cyanocorax cristatellus (Curl-crested Jay)

Wikipedia Abstract

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 crow.
