The scarlet macaw (Ara macao) is a large yellow, red and blue Neotropical parrot native to humid evergreen forests of the Americas. Its range extends from southeastern Mexico to Peru, Ecuador, Colombia, Bolivia, Venezuela and Brazil in lowlands of 500 m (1,600 ft) (at least formerly) up to 1,000 m (3,300 ft), the Caribbean island of Trinidad, as well as the Pacific island of Coiba. Formerly, the northern extent of its range included southern Tamaulipas. In some areas, it has suffered local extinction because of habitat destruction, or capture for the parrot trade, but in other areas, it remains fairly common. It is the national bird of Honduras. Like its relative the blue-and-yellow macaw, the scarlet macaw is a popular bird in aviculture as a result of its striking plumage.
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.
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. Local non-profit organizations have planted hundreds of those trees along the coastline from the Tárcoles 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.
While comparatively docile at most times of the year, scarlet macaws may be formidably aggressive during periods of breeding. Scarlet macaws are monogamous birds, with individuals remaining with one partner throughout their lives. The hen lays two or three white eggs in a large tree cavity. The female incubates the eggs for about five weeks, and the chicks fledge from the nest about 90 days after hatching and leave their parents about a year later. Juveniles reach sexual maturity at five years of age.
The South American range is extensive and covers the Amazon forest, extending to Peru east of the Andes, to Bolivia. In Bolivia, it is common in the Aquicuana Reserve, located in the Beni Department, near the city of Riberalta, the Capital of the Bolivian Amazon.
In Central America, the range extends from extreme eastern and southern Mexico and Panama through Guatemala, El Salvador, Honduras and Belize, the island of Coiba and infrequently on the mainland of Panama, and in Costa Rica in isolated regions on the Pacific Coast; the Nicoya Peninsula the Carara National Park and Peninsula de Osa.
