Like the rest of the genus the wings of the blue-and-yellow macaw are long, as is the tail. The Ara macaws are large parrots ranging from 46–51 cm (18–20 in) in length and 285 to 287 g (10 oz) in weight in the chestnut-fronted macaw, to 90–95 cm (35.5–37.5 in) and 1,708 g (60.2 oz) in the green-winged macaw. The wings of these macaws ...
Furthermore, only the oldest residents of the region had knowledge of the macaw, with the species last recorded in the 1870s. [1] The bird's disappearance probably is linked to trapping of live adults for the wild bird trade and the wholesale felling of the yatay palm, Butia yatay, the nuts of which appear to have constituted its main food.

A macaw's facial feather pattern is as unique as a fingerprint. [4] The largest macaws are the hyacinth, Buffon's (great green) and green-winged macaws. While still relatively large parrots, mini-macaws of the genera Cyanopsitta, Orthopsittaca and Primolius are significantly smaller than the members of Anodorhynchus and Ara.
Blue-and-yellow macaws can live from 30 to 35 years in the wild, and reach sexual maturity between the ages of 3 and 6 years. [7] Little variation in plumage is seen across the range. Some birds have a more orange or "butterscotch" underside color, particularly on the breast. This was often seen in Trinidad birds and others of the Caribbean area.
Military macaws measure from 70 to 85 centimeters (28 to 33 inches) long on-average, with a 99–110 cm (39–43 in) wingspan. The birds are mostly green-plumed, with light-blue and yellow flight and tail feathers, and a bright-red patch on the forehead. Their face is bare, as with most macaws, being whitish in colour with black striations.
The great green macaw belongs to the genus Ara, which includes other large parrots, such as the scarlet macaw, the military macaw, and the blue-and-yellow macaw. [6]This bird was first described and illustrated in 1801 by the French naturalist François Le Vaillant for his Histoire Naturelle Des Perroquets under the name "le grand Ara militaire", using a skin deposited at the Muséum national ...

Spix's macaw is the only known species of the genus Cyanopsitta.The genus name is derived from the Ancient Greek kuanos meaning "blue" and psittakos meaning "parrot". [6] The species name spixii is a Latinized form of the surname "von Spix", hence Cyanopsitta spixii means "blue parrot of Spix". [6]
