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.
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.
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". 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.
In 2001, the ornithologists Matthew Williams and David Steadman supported the idea that the early accounts were a solid basis for believing the Guadeloupe amazon existed. They also 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 (which implies the classification is uncertain). In 2004, Patricia Ottens-Wainright and colleagues pointed out that the early descriptions of the Guadeloupe amazon did not clearly determine whether it was a unique species or the same as the imperial amazon. In 2008 the ornithologists Storrs Olson and Edgar Maíz suggested that the Guadeloupe amazon was probably the same as the imperial amazon. In 2012 the English ornithologist Julian P. Hume stated that though the amazons of Guadelouope and Martinique were base don accounts rather than physical remains, he found it likely they once existed, due to having been mentioned by trusted observers, and on zoogeographical grounds.
In 1905, the British banker and zoologist Walter Rothschild named Anodorhynchus purpurascens, based on an old description of a deep violet parrot seen on Guadeloupe. He interpreted as an Anodorhynchus macaw due to its entirely blue colouration, and stated that the native Caribs called it oné couli. Greenway suggested this "mythical macaw" may have been based on a careless description of the Guadeloupe amazon, or possibly an imported Lear's macaw (Anodorhynchus leari) from South America. He was unable to check the reference given by Rothschild for the old description, but suggested it may have been a work by Martín Fernández de Navarrete. In 2000, the English writer Errol Fuller suggested the bird may have been an imported hyacinth macaw (Anodorhynchus hyacinthinus). In 2001, Williams and Steadman were also unable to find the reference listed by Rothschild, and concluded that the supposed species required further corroboration. James W. Wiley and Guy M. Kirwan were unable to find the reference to the violet macaw too in 2013, but pointed out an account that described how Ferdinand Columbus took parrots that were mainly purple from Guadeloupe.
In 2015, Arnaud Lenoble reviewed overlooked historical Spanish and French texts, and identified the sources Rothschild had based the violet macaw on. The writings of the French missionary Raymond Breton (on Guadeloupe from 1635 to 1654) were especially illuminating, as they showed that both he and the native Island Caribs Lenoble furthermore concluded that the supposed violet macaw was based on misidentified references to the Guadeloupe amazon, and therefore never existed.
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.
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.
Rothschild featured an illustration of the Guadeloupe amazon in his 1907 book Extinct Birds by the Dutch artist John Gerrard Keulemans, based on the early descriptions. In 1916, the American ornithologist Robert Ridgway criticised the illustration for differing from Du Tertre's description in some details.
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.
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. 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;
The amazon parrots still surviving on the West Indian islands are all endangered, since they are trapped for the pet-trade, overhunted for food, and because of destruction of their habitat.
