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:
(Image was now uploaded to Wikimedia under my account "AlephGuira")
Possibly useful information:
- One was seen preying on what looked like Taturanas (https://en.wikipedia.org/wiki/Lonomia), 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 (https://en.wikipedia.org/wiki/Caryocar_brasiliense).
