Cuban parakeet

The Cuban parakeet (Psittacara euops) is a species of bird native exclusively to the island of Cuba. It belongs to the family Psittacidae, which encompasses African and New World parrots. For a period, it was classified under the genus Aratinga, but has since been placed in the genus Psittacara.

Description and Appearance

Adult Cuban parakeets typically measure between 22 to 29 cm (8.7 to 11 inches) in length and weigh between 78 to 96 grams (2.8 to 3.4 ounces). Their plumage is predominantly yellow-green, with paler underparts. A distinctive feature is the scattering of red spots on their head, neck, and breast; these markings are generally more pronounced in males than in females. The edges of their wings and their underwing coverts are a bright red. The undersides of their flight feathers and tail exhibit a pale green to olive hue. Their eyes are light yellow, encircled by bare skin that ranges from light pink to reddish-white. The bill is light pink, and their feet are pink to ivory. Juveniles share a resemblance to adults but exhibit minimal to no red coloration on the head and breast.

Distribution and Habitat

Historically, the Cuban parakeet was found across the main island of Cuba and on Isla de la Juventud (Isle of Pines). However, it was extirpated from Isla de la Juventud by around 1900. In the 21st century, its distribution is fragmented, with populations found in the Zapata Swamp, various provinces including Villa Clara, Ciego de Ávila, Sancti Spíritus, Camagüey, and Guantanamo, as well as in the western Escambray Mountains and the Cauto River watershed.

The species inhabits two distinct ecological landscapes: savannas characterized by numerous palms and scattered trees, and evergreen and semi-deciduous montane forests. Royal palms are a common element in both these environments and are the preferred substrate for nesting.

Behavior and Diet

The Cuban parakeet is a highly social bird, typically observed in flocks that can comprise up to approximately 50 individuals. They are not migratory. Their diet is varied, consisting of seeds, fruits (both mature and immature), flower buds, pollen, and nectar. More than 50 different plant species have been documented as food sources for this parakeet.

Breeding Habits

Breeding for the Cuban parakeet occurs between February and September. Nests are predominantly located in cavities excavated by woodpeckers, although holes in limestone cliffs are also utilized. While no nesting material is added, adults may loosen chips from the inner walls of tree or palm cavities to line the bottom. A clutch typically consists of two to five eggs, with an average of four. The incubation period lasts approximately 24 days, and fledging occurs 55 to 60 days after hatching. The male plays a role in feeding by bringing food to the nest for the female, who then feeds the young.

Vocalizations

The Cuban parakeet possesses a range of vocalizations. Its warning calls, issued in response to predators, are described as metallic and are rendered as 'erh, erh, erh, erh.' The contact call, used while feeding, is characterized as 'kkkkeeeeerrrrrrrrrrrrrr.' A flight contact call, similar to the warning call, is employed during takeoff and landing. Courtship calls are noted as being smooth, short, and sounding like 'keirp-keirp-keirp.'

Conservation Status

The International Union for Conservation of Nature (IUCN) initially assessed the Cuban parakeet as Threatened. Since 1994, it has been rated as Vulnerable. The species faces challenges due to its small and fragmented range, with an estimated population of 1,500 to 7,000 mature individuals that is believed to be declining. Habitat loss and illegal trapping for the pet trade are identified as the principal threats. Furthermore, the increasing severity and frequency of hurricanes, attributed to climate change, pose a potential additional risk. Cuban authorities have suggested that the IUCN rating be elevated to Endangered. A majority of the remaining populations are situated in areas offering some level of protection.
