Blue and Yellow Macaw

These birds can reach 76 to 86 cm (30 to 34 in) long and weigh 900 to 1500 grams (1.9 to 3.3 lbs), making it one of the larger members of its family. They are vivid in appearance with blue wings and tail, dark blue chin, golden under parts, and a green forehead. Beaks are black. The naked face is white, turning pink in excited birds, and lined with small black feathers.

There is little variation in plumage across the range. Some birds have a more orangey or "butterscotch" underside color, particularly on the breast. This was often seen in Trinidad birds and others of the Caribbean area. The Blue-and-yellow Macaw uses its powerful beak for breaking nutshells, and also for climbing up and hanging from trees.
