Areale e habitat

The Cuban parakeet formerly was found throughout the main island of Cuba and on Isla de la Juventud (Isle of Pines). It was extirpated from Isla de la Juventud by about 1900. In the 21st century it has a disjunct distribution in the Zapata Swamp; in parts of Villa Clara, Ciego de Ávila, Sancti Spíritus, Camagüey, and Guantanamo provinces; in the western Escambray Mountains; and in the Cauto River watershed.<p>The Cuban parakeet inhabits two quite different landscapes. One is savannas with many palms and isolated trees. The other is evergreen and semi-deciduous montane forest. Royal palm is present in both landscapes and is the species' preferred nest substrate.

Comportamento

The Cuban parakeet is very social and is usually seen in flocks that may number up to about 50 individuals.<p>The Cuban parakeet is not migratory.<p>The Cuban parakeet's diet includes seeds, fruits (both green and ripe), and flower buds, pollen, and nectar. More than 50 species of plants have been documented as sources. <p>The Cuban parakeet nests between February and September. Almost all nests are in holes excavated by woodpeckers though cavities in limestone cliffs are also used. No material is added to the substrate though in trees and palms the adults may loosen chips from the inner walls to line the bottom of the cavity. The clutch size is two to five eggs with an average of four. The incubation period is about 24 days and fledging occurs 55 to 60 days after hatch. The male brings food to the nest for the female which in turn feeds the nestlings.<p>The Cuban parakeet has a variety of vocalizations. Its "warning calls" in response to a predator are "more metallic than scraping; they can be described as erh, erh, erh, erh." Its "contact call" is used while feeding and is described as "kkkkeeeeerrrrrrrrrrrrrr". It also makes a "flight contact" call, usually when taking off and landing; it is similar to the warning call. "Courtship calls" are "smooth and short...and sound like keirp-keirp-keirp."
