So Chatot is pretty obviously a parrot, right? Well, it's missing something that defines parrots.
Look at the feet (screenshot from Filb). Chatot has three toes in the front and one in the back. Like most bird, right? Only parrots are different. From Wikipedia:
All parrots are zygodactyl, with two toes at the front of each foot and two at the back
On a semi-related note, if they ever made another parrot, they need to base it off the Eclectus parrot because males and females look so different.
