Large red, yellow, and blue Central and South American parrot, a member of a large group of Neotropical parrots called macaws.
It is the national bird of Honduras. Like its relative the blue and gold macaw, scarlet macaws are popular birds in aviculture as a result of their striking plumage.
It is about 81 centimeters (32 in) long, of which more than half is the pointed, graduated tail typical of all macaws, though the scarlet macaw has a larger percentage of tail than the other large macaws. The average weight is about 1 kilogram (2.2 lb). The plumage is mostly scarlet, but the rump and tail-covert feathers are light blue, the greater upper wing coverts are yellow, the upper sides of the flight feathers of the wings are dark blue as are the ends of the tail feathers, and the undersides of the wing and tail flight feathers are dark red with metallic gold iridescence. Some individuals may have green in the wings.
There is bare white skin around the eye and from there to the bill. Tiny white feathers are contained on the face patch. The upper mandible is mostly pale horn in color and the lower is black. Juveniles have dark eyes; adults have light yellow eyes.
It is frequently confused with the slightly larger green-winged macaw, which has more distinct red lines in the face and no yellow in the wing.
Scarlet macaws make very loud, high and sometimes low-pitched, throaty squawks, squeaks and screams designed to carry many miles to call for their groups.
The scarlet macaw can live up to 75 or even 90 years in captivity, although a more typical lifespan is 40 to 50 years.
Scarlet macaws eat mostly fruits, nuts and seeds, including large, hard seeds and sodium packed dirt.
They are monogamous birds, with individuals remaining with one partner throughout their lives.
