“ MACAW, or, as formerly spelt, Maccaw, the name given to some fifteen or more species of large, long-tailed birds of the parrot-family, natives of the neotropical region, and forming a very well-known and easily recognized genus Ara, and to the four species of Brazilian Hyacinthine macaws of the genera Anodorhynchus and Cyanopsittacus. Most of the macaws are remarkable for their gaudy plumage, which exhibits the brightest scarlet, yellow, blue and green in varying proportion and often in violent contrast, while a white visage often adds a very peculiar and expressive character. ”
