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).

Red-lored Amazon
Amazona autumnalis
The red-lored amazon is 32–35 centimetres (13–14 in) in length, with a weight of 310–480 g. The plumage is primarily green, with a red forehead and, in some subspecies, yellow cheeks (sometimes with red spots). The crown is blue. Adult males and females do not differ in plumage. Juveniles have less yellow on the cheeks, less red on the forehead, and dark irises.
