Seven species are found in Bolivia, but no single locality in that (or any other) country surpasses four species. The centre of Ara distribution is the Amazon Basin and the Panama– Colombia border region each with as many as four species found together (marginally five where the military macaw approach the western Amazon). The Ara macaws have a Neotropical distribution from Mexico to Argentina.
There is no sexual dimorphism in the plumage, and the plumage of the juveniles is similar to adults, although slightly duller in some species. Four species are predominantly green, two species are mostly blue and yellow, and three species (including the extinct Cuban macaw) are mostly red. The colours in the plumage of the Ara macaws are spectacular. In most species the bill is black, but the scarlet macaw and green-winged macaw have a predominantly horn coloured upper mandible and a black lower one.
The eyes of ara hidden skin#
The skin patch bears minute feathers arranged in lines that form a pattern over the otherwise bare skin in all species of the genus except the scarlet macaw in which the skin is bare. They have a massive downward curved upper mandible and a patch of pale skin around the eye that extends to base of the beak. The wings of these macaws are long and narrow, which is typical for species of parrot which travel long distances in order to forage. 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.
Like the rest of the genus the wings of the blue-and-yellow macaw are long, as is the tail
