Hyacinth Macaw

 

Anodorhynchus hyacinthinus

SUBFAMILY

Psittacinae

TAXONOMY

Psittacus hyacinthinus Latham, 1790, Brazil. Monotypic.

OTHER COMMON NAMES

English: Hyacinthine macaw; French: Ara hyacinthe; German: Hyazinthara; Spanish: Guacamayo Jacinto.

PHYSICAL CHARACTERISTICS

39 in (100 cm); weight not recorded. Largest and probably most spectacular of all parrots. Deep blue plumage, yellow eye patch and chin, long tapering tail.

DISTRIBUTION

North Brazil to east Bolivia and extreme north Paraguay.

HABITAT

Lightly to moderately wooded country where palm food trees are present; favors gallery woodland traversing semi-open lands, especially seasonally inundated grasslands of the Pantanal; occurs also at margins of moist, lowland forest and in low, dry scrublands or cerrado with scattered clumps of Mauritia palms.

BEHAVIOR

At extremities of range seasonal movements influenced by fruiting of palms, but elsewhere largely sedentary. Usually in groups of six to 12, and mated pairs or parents with offspring readily discernible, but singly or in pairs during breeding season. Noisy and conspicuous, especially in flight, and when disturbed rises up from treetops to circle overhead while screaming loudly; rests quietly in uppermost branches during heat of the day, paired birds sitting together and allopreening frequently; long-distance flights between nighttime roosts and feeding areas at great height, pairs normally traveling together, one beside and slightly behind its mate, and long, streamer-like tail giving distinctive appearance.

FEEDING ECOLOGY AND DIET

Principally fruits of palms, procured in trees or on the ground underneath; takes palm seeds from cattle droppings or seeds remaining after pulp has been eaten by foraging mammals. Ficus and other fruits sometimes eaten, and recorded taking of Pomacea snails from shallow ponds.

REPRODUCTIVE BIOLOGY

Monogamous. Breeding recorded from July to December. In northern Brazil nests commonly in crevices in cliff-faces, but elsewhere in tree hollows, often in dead palm stumps; clutch of two or rarely three eggs, but normally only one chick reared; in captivity incubation by female lasted 28–30 days; young bird fledged at approximately three months.

CONSERVATION STATUS

Endangered and listed on CITES Appendix I. Alarming declines caused by capture of adults and removal of nestlings for live-bird trade, exacerbated by land clearance and hunting for food or feathers. In early 1990s total population estimated at fewer than 3,000.

SIGNIFICANCE TO HUMANS

Very much in demand as aviary bird; also hunted for food and feathers.

The Hyacinth Macaw's distribution is colored in red

Native to central and eastern South America, the Hyacinth Macaw (Anodorhynchus hyacinthinus), or Hyacinthine Macaw, is the largest macaw and the largest flying parrot species in the world, though the flightless Kakapo of New Zealand can outweigh it at up to 3.5 kg. In terms of length it is larger than any other species of parrot. While generally easily recognized, it can be confused with the far rarer Lear's Macaw. Their popularity as pets has taken a heavy toll on their population in the wild.

Description

The Hyacinth Macaw is 100 cm (39 in) long and 1.5–2 kg (3.3-4.4 lb) in weight. The wingspan is 120–140 cm (48–56 in). It is almost entirely blue and has black under the wings. It has a large black beak with bright yellow along the sides of the lower part of the beak and also yellow circling its eyes.[1] The female and male are nearly indistinguishable, although the female is typically a bit more slender.

Behaviour

Upper body

Food and feeding

They have a very strong beak for eating their natural foods, which include the kernel of hard nuts and seeds. Their strong beaks are even able to crack coconuts and macadamia nuts. In addition, they eat fruits and other vegetable matter. Pine nuts are also one of the most popular foods. They will also take snails.

Reproduction

These birds nest in existing holes in trees. The clutch size is one or two eggs, although usually only one fledgling survives as the second egg hatches several days after the first, and the smaller fledgling cannot compete with the first born for food. Juveniles stay with their parents until they are three months old. They are mature and begin breeding at seven years of age. Eggs are regularly predated by corvids, possums, coatis and (most prolifically) toucans.[2] Adults have no known natural predators.[3]

Distribution and habitat

Hyacinth Macaws in their natural habitat, the Pantanal, Brazil.

The Hyacinth Macaw survives today in three main populations in South America: In the Pantanal region of Brazil, and adjacent eastern Bolivia and northeastern Paraguay, in the Cerrado region of the eastern interior of Brazil (Maranhão, Piauí, Bahia, Tocantins, Goiás, Mato Grosso and Minas Gerais), and in the relatively open areas associated with the Tocantins River, Xingu River, Tapajós River, and the Marajó island in the eastern Amazon Basin of Brazil. It is possible that smaller, fragmented populations occur in other areas. It prefers palm swamps, woodlands, and other semi-open wooded habitats. It usually avoids dense humid forest, and in regions dominated by such habitats, it is generally restricted to the edge or relatively open sections (e.g. along major rivers).

Conservation

At La Palmyre Zoo, France

The Hyacinth Macaw is an endangered species due to overcollection for the cage bird trade and habitat loss. Annual grass fires set by farmers can destroy nest trees, and regions previously inhabited by this macaw are now unsuitable due to cattle-ranching, hydroelectric power schemes, agriculture and plantations. Locally, it has been hunted for food, and the Kayapo Indians of Gorotire in south-central Brazil use its feathers to make headdresses and other baubles. While overall greatly reduced in numbers, it remains locally common in the Brazilian Pantanal, where a specific program, the Hyacinth Macaw Project, among others involving artificial nests and awareness campaigns, has been initiated by several ecolodges, and many ranch-owners now protect the macaws on their land.

The Minnesota Zoo with BioBrasil [4] and World Wildlife Fund[5] are involved in Hyacinth Macaw conservation.
