A highly social and conspicuous species, the Cuban parakeet typically forages in family groups or small flocks (2). Although largely frugivorous, it will also eat the seeds of palms, pines and various other tree species. The Cuban parakeet will also take the fruit of orange trees, the heads of maize and the berries of coffee, a behaviour that has labelled the species as a crop pest (4). This species flies between trees with a swift, direct flight and may be extremely vocal, calling with an array of chatters, squeaks and shrieks (6).
In common with most other parakeets, the Cuban parakeet is probably monogamous, mating with its partner for life. Pairs remain together constantly and reinforce the pair bond by feeding and preening together (6). Breeding takes place between April and July, coinciding with a peak in the productivity of fruit trees, and nests are constructed in holes in old trees, such as dead Roystonea regia and Sabal palviflora palms (4) (5). A clutch of three to five eggs is incubated for 23 to 25 days, and the young chicks will remain in the nest for 45 to 50 days before fledging (4).
