Can someone identify this Brazilian bird? Photographing and documenting the local fauna (Brasília, DF, Brazil - Near Coordinates [-15.696506 -47.860013]), I found this rather unusual-looking bird whose name I couldn't find: * * * ![Two birds with long, kind of spiky-looking feathers on their heads, dark wing, beige-ish white chest and long tail feathers]( * * * (Image was now uploaded to Wikimedia under my account "AlephGuira") Possibly useful information: * One was seen preying on what looked like _Taturanas_ (< but due to their venomous nature, I'm not sure. * The observed flock was composed of 7 birds. * There seems to be sexual dimorphism (The other one, not pictured, seems to be smaller, has shorter head feathers, whiter wings and lacks the orange-pointed beak). * They were first seen on a _Pequi_ Tree (<

These look very similar to the Guira cuckoo ( _Guira guira_ ) which are found in this part of Brazil.
