The iris is a thin, circular structure in the eye, responsible for controlling the diameter and size of the pupils and thus the amount of light reaching the retina.

, and a larger rosy pink throat patch than A. l. leucocephala of the Cuban mainland. This review also revealed differences among the populations on the various islands in the Bahamas (some of which had already been pointed out earlier), leading to the suggestion of restricting A. l. bahamensis to the now extirpated population of the Acklins and Crooked Islands, while it was proposed that the two extant populations from the Abaco Islands and the Inagua Islands each represent a new subspecies. The recognition of three subspecies from the Bahamas is also supported by genetics.

Distribution and habitat

The Cuban Amazon lives in different habitats on different islands. It was once found throughout Cuba, but it is now mainly confined to the forested areas of the main island and Isla de la Juventud. There are about 10,000 individuals in Cuba including an estimated 1,100–1,320 on Isla de la Juventud.

On the Cayman Islands the parrot lives in dry forest and on agricultural land. The population living on Grand Cayman numbers about 3,400 individuals (2006 survey), and the population on Cayman Brac consists of 400–500 individuals. The population on Little Cayman was extirpated in the 1940s.

The populations were estimated at about 3,550 individuals on Abaco and 6,350 on Inagua in 2006. The population on the Acklins and Crooked Islands was extirpated in the 1940s, while it, based on fossil

Behaviour

In the winter Cuban Amazons gather in flocks, and disperse into pairs during the breeding season.

Breeding
