The Blue-and-yellow Macaw is a member of the macaw group of parrots which breeds in the swampy forests of tropical South America from Panama south to Brazil, Bolivia and Paraguay. These macaws reach 34 inches in length and weigh 34 to 46 ounces. They are vivid in appearance with blue wings and tail, golden underparts and a green cap on the head. Their beaks are black and very strong for crushing nuts.
The Harlequin Macaw is a beautiful hybrid cross between this species and the Red-and-green Macaw. The coloration of the hybrid bird depends on which parent is which species; if the father is a Red-and-green, the Harlequin will generally be the size of a Red-and-green with the coloration of the Blue-and-yellow.
