The Guadeloupe amazon or Guadeloupe parrot (Amazona violacea) is a hypothetical extinct species of parrot that was endemic to Guadeloupe. It was hunted, and by 1779 was already rare. Today it is extinct.

Taxonomy

The Guadeloupe amazon was first mentioned and described by the French botanist Jean-Baptiste Du Tertre in his 1664 Histoire Générale des Isles des Christophie, de la Guadeloupe, de la Martinique, et autres dans l'Amérique, and in subsequent works. The French clergyman Jean-Baptiste Labat described the bird in 1742, and it was mentioned by later natural history writers such as Mathurin Jacques Brisson, Comte de Buffon, and John Latham, the latter which gave it the name "ruff-necked parrot". The German naturalist Johann Friedrich Gmelin coined the scientific name Psittacus violaceus for the bird in his 1789 edition of Systema Naturae, based on the writings of Du Tertre, Brisson, and Buffon.[2][3]

In 1891, the Italian zoologist Tommaso Salvadori included Psittacus violaceus in a list of synonyms of the red-fan parrots (Deroptyus accipitrinus), a continental species. In 1905, the American zoologist Austin Hobart Clark pointed out that the colouration of the two species was dissimilar (their main similarity being a frill on the neck), and that Buffon stated the Guadeloupe bird did was not found in Cayenne, where the red-fan parrot lives. Clark instead suggested that the Guadeloupe species was most closely related to the similarly coloured imperial amazon (Amazona imperialis) of Dominica. He therefore placed the Guadeloupe bird in the same genus, as Amazona violacea, and referred to it by the common name "Guadeloupe parrot".[2][4]

In 1967, the American ornithologist James Greenway suggested that the parrot of Guadeloupe may have formed a superspecies with the imperial amazon and the extinct Martinique amazon (Amazona martinicana), and was perhaps a subspecies of the former.[5][6] In 2001, the ornithologists Matthew Williams and David Steadman reported a tibiotarsus bone found on the Folle Anse archaeological site on Marie-Galante, an island in the Guadeloupe region. They found it similar to that of the imperial amazon, but slightly shorter, and due to the fact that Maria Galante shares many modern bird species with Guadeloupe, they found it likely that the bone belonged to the Guadeloupe amazon, and assigned it to A. cf. violacea.[7] Storrs Olson and Edgar Maíz consider "A. violacea" as probably identical to the living species.[8][9]

The violet macaw (Anodorhynchus purpurascens) was described by Rothschild and featured in his book, Extinct Birds published in 1907.[10][11] Its native name was supposedly oné couli. Rothschild named the species because uniform bluish coloured macaws were said to have inhabited the island of Guadeloupe,[12] but the recent tracing of the sources used by Rothschild has evidenced the author based on a poor depiction of the Guadeloupe Amazon by Raymond Breton, a French missionary present in Guadeloupe during the first years of the French colonization.[13] Only the genus Ara is thus known to have colonised the West Indies.[6]

Description

Hypothetical illustration of the Guadeloupe amazon by Keulemans, 1907

Du Tertre described the Guadeloupe amazon as follows in 1654:

The Parrot of Guadeloupe is almost as large as a fowl. The beak and the eye are bordered with carnation. All the feathers of the head, neck, and underparts are of a violet color, mixed with a little green and black, and changeable like the throat of a pigeon. All the upper part of the back is brownish green. The long quills are black, the others yellow, green, and red, and it has on the wing-coverts two rosettes of rose color.[2]

Labat described the bird as follows in 1742:

The Parrots of these islands are distinguishable from those of the mainland of Guinea (? Guiana) by their different plumage; those of Guadeloupe are a little smaller than the Macaws. The head, neck, and underparts are slaty, with a few green and black feathers; the back is wholly green, the wings green, yellow, and red.[2]

Behaviour and ecology

Du Tetre described some details of their breeding behaviour:

We had two which built their nest a hundred paces from our house in a large tree. The male and the female sat alternately, and came one after the other to feed at the house, where they brought their young when they were large enough to leave the nest.[2]

Extinction

Guadeloupe is less mountainous than Dominica, and the human population was larger, which would have led to a larger pressure on the Guadeloupe amazon than the one on Dominica. The Guadeloupe amazon appears to have gone extinct by the end of the 18th century.[6] In 1779, Buffon stated the bird had become very rare, and perhaps extinct:

We have never seen this parrot, and it is not found on Cayenne. It is even rare in Guadeloupe to-day, for none of the inhabitants of the island have given us any information concerning it;[2]
