The Puerto Rican Amazon typically occurs in pairs, with nests made in natural tree cavities and used year after year (2). The breeding season is from late February to July (7) and the clutch size ranges from two to four eggs, although many pairs fail to lay eggs in a season (2). Incubation is performed by the female only, and lasts for around 26 days (6). Young fledge at approximately nine weeks of age (6) (8) and reach sexual maturity after three to five years (8). Diet mainly consists of wild fruits, particularly the sierra palm (Prestoria montana), but flowers, leaves, seeds, bark and tender shoots may also be eaten, with up to 60 food plants recorded in the diet (6).
