It is native to humid evergreen forests in the American tropics. Range extends from extreme south - eastern Mexico to Amazoniain Peru and Brazil, in lowlands up to 500 m (1,640 ft) (at least formerly) up to 1,000 m (3,281 ft). It has been widely extirpated by habitat destruction and capture for the pet trade. Formerly it ranged north to southern Tamaulipas. It can still be found on the island of Coiba. It is also the Honduran national bird.

Description

It is about 81 to 96 cm (32 to 36 inches) long, of which more than half is the pointed, graduated tail typical of all macaws. The average weight is about a kilogram (2 to 2.5 pounds). The plumage is mostly scarlet, but the rump and tail-covert feathers are light blue, the greater upperwing 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. Three subspecies present varying widths in their yellow wing band. 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. Sexes are alike; the only difference between ages is that young birds have dark eyes, and adults have light yellow eyes.

Scarlet Macaws make loud, low-pitched, throaty squawks, squeaks and screams designed to carry many miles to call for their groups.
Behavior

The Scarlet Macaw can live up to 75 years, although, a more typical lifespan is 30 to 50 years.

Diet

Scarlet Macaws eat mostly fruits and seeds, including large, hard seeds. 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 may gather at clay licks. They like apples, nuts, bananas, and fruits. They also feed on nectar and buds.

Breeding

The Scarlet Macaw lays two or three white eggs in a tree cavity. The female incubates the eggs for about 28 days, and the chicks fledge from the nest about 90 days after hatching and leave their parents about a year later.


Distribution and habitat

Scarlet Macaws originate in the humid lowland subtropical rain forests, open woodlands, river edges, and savannas of Central and South America. The habitat of the Central American Scarlet Macaw runs through the extreme eastern and southern regions of Mexico and Panama, but also through Guatemala and Belize, while the South American population has an extensive range that covers the Amazon basin; extending to Peru east of the Andes, to Bolivia, and Paraguay. While generally infrequent on the mainland, great colonies of Scarlet Macaws can still be found on the islands of Coiba.

Before the Scarlet Macaw's decline in population, its distribution included much of Costa Rica. However, by the 1960s Scarlet Macaws had been decreasing in numbers due to a combination of factors, particularly hunting, poaching, and the destruction of habitat through deforestation. Further, the spraying of pesticides by companies cultivating and selling bananas for export played a significant role in decreasing Scarlet Macaw populations.

The combined factors stressed the population of Scarlet Macaws in Costa Rica, where they had previously occupied approximately 42,500 km² of the country's total national territory of 51,100 km², leaving viable populations in the early 1990s isolated to only two regions on the Pacific Coast of Costa Rica; the Carara Biological Reserve and Peninsula de Osa. By 1993 surveys had shown Scarlet macaws occupied only 20% (9,100 km²) of their historic range in Costa Rica.

The habitat of Scarlet Macaws is considered to be the greatest latitudinal range for any bird in the genus Ara, as the estimated maximum territorial range covers 6,700,000 km². Nevertheless, the Scarlet macaw’s habitat is fragmented, and colonies of the bird are mostly confined to tiny populations scattered throughout Central and South America. However, as they still occur in large numbers in some parts of their territory, where they are described as "common," the World Conservation Union evaluated the species in 2004 as "Least Concern".

Aviculture, captivity, and care

Scarlet Macaws are popular, but are a high maintenance pet; they are expensive to purchase, adopt, or maintain, they are demanding, and they are extremely loud and noisy cage birds. They are prized for their beautiful plumage and considered very affectionate with their owners. They are considered an intelligent species. Many hybrids between this and other macaw species are popular and different variations of coloring are numerous like the one pictured at the right.

The Scarlet Macaw is a CITES I listed species, meaning that they are illegal to take from the wild without specific special permits. They are not endangered as of 2008 but are very vulnerable to the pet trade. Like many rarer parrot species today, they are occasionally smuggled to the United States or Canada where they wind up seized by authorities in Miami, San Juan, Toronto, or New York City (both nations are CITES signatories and thus obligated to take appropriate action). Unfortunately not all perpetrators are caught and some birds are sold illegally. Many smuggled parrots die from stress on their way to points north.


Scarlet Macaws require a large amount of room and thus the cage a single bird occupies should be as large as possible, 36 inches wide x 36 inches deep x 60 inches high, or larger. They need ample amounts of room to prevent the muscles in their wings from atrophying as well as plenty of room to play, exercise in, and spread their wings. The bars of the cage should be no larger than 1 inch apart and should be made of durable metal. It should not have parts that contain lead or zinc, including paint on the bars. Cage cleaning and hygiene are important, Many cages have a grate covering the base to separate the bird from its droppings. The cage should be placed in an area that is off the floor, well-lit, and of a consistent temperature. Perches are acceptable and recommended; perches of varied materials and size are required to keep feet healthy. Stands placed strategically around the house are important as an additional place to hang out and be part of the family. A spray bottle of lukewarm water can be used to bathe the bird. (All macaws typically like water and will also respond happily to an outing in the kitchen sink as well or spray down in the shower or with a garden hose.) They should eat a diet that mimics what they eat in the wild (fruit, vegetables, nuts, and seeds) but if given nuts should ideally be given those with a higher fat content (hazelnuts, Brazil nuts, walnuts, etc.)


In addition to requiring large spaces Scarlet Macaws equally require a great deal of stimulation, attention, and affection. They thrive on,and need frequent, regular interaction. They should be removed from their cages for long periods to socialize and be slowly socialized with others to retain a friendly disposition towards people; they need time to get to know strangers. They will naturally be extremely vocal and should not be discouraged from this behavior but should be given limits overall. Children are not recommended to have this bird as a pet and in particular should interact with Scarlet Macaws under adult supervision and taught to respect a large, very sensitive bird with a powerful beak adapted to crushing hard nuts. They love to play and should have plenty of toys in good condition for stimulation; they habitually chew whatever they can get their beaks on and so wooden toys are recommended both for enrichment and to avoid beak overgrowth. Toys that are worn out should be replaced and care should be taken to keep a Scarlet Macaw's curious mind occupied. Birds that do not receive enough attention often display behaviors of over-preening, self-mutilation, depression, and extreme rage/aggression.
