The bare-faced curassow (Crax fasciolata) is a species of bird in the Cracidae family, the chachalacas, guans, curassows, etc. Males and females are quite different as you can see in these pics I took in the Pantanal.
Male
Female
They have quite a large range throughout Brazil, Paraguay and Bolivia. Probably the easiest place to see them is in Brazil’s Pantanal.

Sadly I couldn’t find a video of them in the wild but this clip of captive birds shows the sounds they make.
