Genus

Amazon parrot is the common name for a parrot of the genus Amazona. These are medium-size parrots native to the New World ranging from South America to Mexico and the Caribbean. Most Amazon parrots are predominantly green, with accenting colors that depend on the species and can be quite vivid. They have comparatively short, somewhat square, tails. Just like the other parrots, amazons have four toes on each foot, two pointing forwards and two pointing backward. They feed primarily on seeds, nuts, and fruits, supplemented by leafy matter. Almost everywhere in the lowlands of tropical and subtropical America, the savannas, grassy openings in the forest, and roadsides are frequented by flocks of very small finches with short and thick bills, which feed on the seeds of grasses. In the genus Sporophila, the males are clad in black, black and white, or black and chestnut, while the dull females are olive or buff. Often the same species shows pronounced variation in plumage from region to region.

Conservation

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
