Mealy Amazon
Amazona farinosa
The mealy amazon has a total length of about 38–41 cm (15–16 in) and weighs 540–700 g (19–25 oz). Captives commonly are heavier. It is among the largest parrots in the Americas, mainly being surpassed by the large macaws. It has a relatively short and square shaped tail, as do the other members of the Amazona genus. The mealy amazon is mainly green. The back and nape often have a whitish tinge; almost as if it had been covered in a thin layer of flour ("meal"; hence its name).
