Value: Resident locally in the Americas along the northern coast of the Yucatan Peninsula (Celestún, Río Lagartos), in the Greater Antilles (Cuba, Hispaniola, and probably Gonâve and Beata islands), in the southern Bahamas (Acklins Island and Great Inagua), in the Netherlands Antilles (Bonaire) and in the Galapagos Islands. Formerly bred in the Florida Keys (once, possibly), widely in the Bahamas, locally from Culebra and Anegada to the Virgin Islands, and along the north coast of South America from Colombia to the Guianas. Wanders to southern Florida (where captive flocks are also established), widely through the Bahamas and Antilles, and along the east coast of the Yucatan Peninsula (including Cozumel Island) and northeastern South America from Colombia to northern Brazil. Casual or accidental (but many if not all probably pertaining to escaped individuals) along the Gulf coast from Texas to Florida, inland north to Kansas, Michigan, Ontario, and southern Quebec, along the Atlantic coast north to New Brunswick and Nova Scotia, and to Bermuda and the Cayman Islands; reports from Washington, California, and Nevada almost certainly pertain to escaped individuals.
