Macaws, Cockatoos, Greys, Poicephalus, Conures, Lovebirds, Parrotlets, Parakeets etc. Discuss topics related to specific species of parrots and their characteristics, mutations, pros, and cons.
I have no experience with Hawkheaded Parrots, but from what I've heard/read, they describe them like the devil! "Aggressive one-person birds that bite on impulse. They attack for no reason." I believe that no bird is like that. Aggressive maybe, but never without a reason.
