Kaytee is 12 years old and the largest of the macaws. He is a very pleasant bird but is rather quiet, unlike Leo, our Birds on the Brink spokes-bird. Kaytee and Leo are both Harlequin Macaws or what one might call a hybrid macaw. They are produced by breeding a Green Wing Macaw and a Blue and Gold Macaw.
You may not know this, but in general, the larger the bird, the longer the lifespan. Most of the larger parrots have lifespans similar to humans and, in some cases, even greater.
