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.
Rather, the macaws and other bird and animal species prefer clays with higher levels of sodium. [17] Sodium is a vital element that is scarce in environments greater than 100 kilometres from the ocean. [ 18 ]

English physician, ornithologist, and artist John Latham first described the hyacinth macaw in 1790 under the binomial name Psittacus hyacinthinus. [3] Tony Pittman in 2000 hypothesized that although the illustration in this work appears to be of an actual hyacinthine macaw, Latham's description of the length of the bird might mean he had measured a specimen of Lear's macaw instead. [4]
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 ...
