Bouton's 1630s description of the Martinique macaw is reproduced below, translated from French:
The macaws are two or three times as large as the other parrots, [and] have a plumage much different in colour: those that I have seen have their plumage blue and orange-yellow (saffron).
They also learn to talk and have a good body.

A translation of the 1658 French description of "Ara erythrura" by de Rochefort follows below:
Among them are some which have the head, the upper side of the neck, and the back of a satiny sky blue; the underside of the neck, the belly, and undersurface of the wings, yellow, and the tail entirely red.

In spite of the fact that the tail of "Ara erythrura" was described as entirely red, the plate in Rothschild's Extinct Birds showed a blue tip, which the American ornithologist Charles Wallace Richmond complained about in his review of the book.
