about . 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 kilometers 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. Behavior A typical sighting is of a single bird or a pair flying above the forest canopy, though in some areas flocks can be seen. They often gather at clay licks. Scarlet macaws communicate primarily through raucous honks; however, vocal communication is highly variable, and captive macaws are known to be adept mimics of human speech. Feeding Wild scarlet macaws feed on fruits, nuts, seeds, flowers and nectar. They also love to eat insects and larvae. They are seen feeding heavily on bugs, snails and foliage. Snails and bugs are great source of protein, as they need additional protein during breeding seasons. In Costa Rica's Central Pacific they have learned to feed on introduced Teak trees (Tectona grandis) and Almond Beach Trees (Terminalia sp). The local non-profit organizations have planted hundreds of those trees along the coastline from Tarcoles River basin to Esterillos Beach which had helped increase the population drastically. The combined efforts and the correct ecotourism has also an important role in the conservation of such majestic birds. Tour companies along the Tarcoles River and its mangroves have bet on the importance of birdwatching as an asset for the growth on its population. Breeding While comparatively docile at most times of the year, scarlet macaws may be formidably aggressive during
