The Cuban amazon was
formally described in 1758 by the Swedish naturalist
Carl Linnaeus in the
tenth edition of his
Systema Naturae. He placed it with all the other parrots in the
genus Psittacus and coined the
binomial name Psittacus leucocephalus. Linnaeus cited the description and illustration of the "white-headed parrot" in
George Edwards'
A Natural History of Uncommon Birds which was published in 1751. Linnaeus gave the
type locality as "America" but this was restricted to eastern Cuba by
Thomas Barbour in 1923. The Cuban amazon is now one of around thirty species placed in the genus
Amazona that was introduced by the French naturalist
René Lesson in 1830. The genus name is a Latinized version of the name
Amazone used in the 18th century by the
Comte de Buffon. The specific epithet
leucocephala is from
Ancient Greek leukokephalos meaning "white-headed" (from
leukos meaning "white" and "-kephalos" meaning "-headed"). Traditionally, most authorities have recognized four
subspecies of the Cuban amazon, •
A. l. leucocephala (
Linnaeus, 1758), also called the Cuban amazon. Present throughout
Cuba, including
Isla de la Juventud (formerly known as Isla de Pinos). •
A. l. bahamensis (
Bryant, H, 1867), also called the Bahaman amazon. Two
extant populations in
the Bahamas; one on the
Abaco Islands and one on
Great Inagua (with sightings from nearby
Little Inagua).
Extirpated populations were present on the
Acklins and Crooked Islands and possibly elsewhere in the Bahamas as well. •
A. l. caymanensis (
Cory, 1886), also called the Grand Cayman amazon. Restricted to
Grand Cayman Island. •
A. l. hesterna Bangs, 1916. Now restricted to the island of
Cayman Brac, but formerly also on
Little Cayman Island. Another subspecies,
A. l. palmarum (
Todd, 1916) was thought to occur in western Cuba (east to
Villa Clara Province) and Isla de la Juventud based on differences in the
plumage, but in 1928 a re-evaluation indicated that the colour differences were due to age-related variations and that they showed no substantial differences to the specimens obtained from the rest of Cuba (i.e.,
A. l. leucocephala sensu stricto). but some authorities have maintained that
A. l. palmarum is a valid subspecies. A recent review based on
morphology and plumage supported the distinction of
A. l. palmarum (at least if restricted to the population on Isla de la Juventud), it having a longer
wing chord and
metatarsus, 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. ==Description==
