In Puerto Rico, the most common bird is called La Cotorra (The Puerto Rican Amazon). This is a BEAUTIFUL bird. The Puerto Rican Amazon measures 28–30 cm (11–12 in) and weighs 250–300 g (8.8–11 oz), or 275 g (9.7 oz) on average. Although small compared to Amazons in general, it is similar in size to other Greater Antilles Amazona species. Both males and females have predominantly green plumage, though their feathers have blue edges. The primary flight feathers of the wings and the main covert feathers are dark blue. The color of the feathers on the underside varies depending on the body part: the feathers on the underside of the wings, which can be seen during flight, are bright blue; those in the tail have yellow-green tone. One of the only problems is that this bird is in danger of dissapearing. Here are some pictures of this type of bird and its colors:
