Scarlet Maccaw and Yellow Ridge Toucan by Genkicoll

Scarlet Macaw

The Scarlet Macaw (Ara macao) is a large, colorful Macaw. Some consider the Scarlet to be among the most beautiful birds in the world.

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 on the wings near the yellow band. 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.

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".

Yellow-ridged Toucan

The Yellow-ridged Toucan (Ramphastos vitellinus culminatus) is a subspecies of the Channel-billed Toucan (Ramphastos vitellinus). It is a near-passerine bird which breeds in Trinidad and in tropical South America east of the Andes and as far south as southern Brazil. The western form of this bird, the Yellow-ridged Toucan, was previously considered to be a separate species, Ramphastos culminatus, but the two races readily interbreed.

This species is a resident breeder in moist lowland forest. The white eggs are laid in a high unlined tree cavity.

Like other toucans, the Channel-billed is brightly marked and has a huge bill. It is typically 48cm long with a 9-14cm bill. Sexes are similar. Both sexes are alike in appearance, and they are both active in raising the young. There is have a gestation period of 18 days, and the parents both incubate for 15 to 16 days. However, they can be impatient sitters, often leaving their eggs uncovered for hours at a time. Newborn toucans remain in the nest after hatching. They are blind and naked at birth, and their eyes open after about 3 weeks. They have short bills and specialized pads on their heels to protect them from the rough floor of the nest. The featheres do not begin to expand until they are nearly 4 weeks old. They're helpless and unable to leave the nest for about 8 weeks, dependent upon both parents to feed them. After this, the young can care for themselves. They begin to leave the nest after 40 to 50 days, depending on size.

The eastern nominate race has a black bill, upperparts and tail, and a red rump. The bare eyepatch and bill base are blue, the throat is white and the breast shows successive bands of yellow, whitish and red before reaching the black belly. The undertail is black apart from red undertail coverts.

The subspecies culminatus has a yellow top ridge to its black bill, and the throat and breast are white, with just a red band separating the latter from the black belly.

The Channel-billed Toucan is an arboreal fruit-eater, but will take insects and other small prey. The call is a croaking cree-op cree-op cree-op.

NOTE: These birds are 100% compatible. Both will say that "There are more shelters than necessary in this exhibit", but they do not actually mind having the sunken ship in their exhibit... They actually like one there!
