From their large size, the length of their tails, and the gorgeous tints of blue, red, and yellow adorning their plumage, the macaws are the most showy and conspicuous of all the parrots ; but they have the disadvantage of being the most noisy of the whole confraternity, and are therefore far from desirable in the house, By many writers the whole of them are included in a single genus, but Count.Salvadori considers that they may be divided into three generic groups. The hyacinthine macaw (Anodorhynchus hyacinthinus), from Central Brazil, of which a figure is given on the left side of our coloured Plate, is the best known representative of a small genus, characterised by the general colour of the plumage being blue both above and below, while the lores are feathered. In the figured species the whole plumage is of a nearly uniform cobalt-blue, becoming a little lighter on the head and neck, and somewhat duller below, while the under surface of the wings, and tail is black. In marked contrast to the prevailing azure, stands out the yellow of the naked skin surrounding the eye and at the base of the lower jaw. The black beak is of unusually large size even for a macaw, and the feet are blackish. The total length of this fine bird is about 34 inches, of which 201/2 are taken up by the tail. The hyacinthine macaw is a somewhat rare species, and although inhabiting the dense tropical forests affected by the other macaws, it is said by Azara to differ markedly in regard to its breeding habits. In place of building in some hollow tree, it is stated to scoop out a burrow on the bank of a river, where it lays a pair of eggs; two broods being reared in a season. These birds - the ararauna of the natives, fly, according to Bates, in pairs, and feed on palm-nuts, which, although so hard as to be difficult to break with a heavy hammer, are crushed to pulp by their beaks. The skulls of the hyacinthine macaw and its congeners differ from those of ordinary macaws in the incompleteness of the bony ring round the eye. The same feature is probably also characteristic of Spix's Macaw (Cyanopsittacus spixi), which although agreeing with the ararauna in its blue coloration, differs by the naked lore, on which account it is regarded as representing a distinct genus.

Blue macaws help to grow the forest around them
I have loaded a very recent interesting article (August 2020) on how the blue macaws - Hyacinthine and Lear’s - help to grow the forests around them. It is in the article section for "Hyacinthine Macaws in the wild".... Read More »
