The Macaw IS an amazing cobalt blue, which is how they derived their name. The blue feathering becomes slightly darker on the wings, and the underside of the tail is a dark gray. They have a featherless ring circling the eye that is a bright daffodil yellow. This color is also found running down both sides of their gray-black beak. This combination makes the Hyacinth appear to smile. Their eyelashes are blue and the skin of the bird has a yellowish cast to it except for the legs, which are a dark gray. Their beak is quite large enabling them to meet their dietary requirements by cracking extremely hard nuts. This parrot is the largest of the Macaws, measuring often three and one-half feet in length with a wingspan of close to five feet. These are a large, full sized Macaw. A mature adult averages about 37 inches (95 cm) in length with a wingspan that can reach an impressive 42" (105 cm), and they can weigh up to about 3.7 lb (1.7 kg). These Macaws are also quite long lived, with lifespan up to about 60 xxxxx.xxx contact me at:::xxxxxxxxxxxxxx@xxxxx.xxx
