Hyacinthine macaw
The Hyacinth macaw (Anodorhynchus hyacinthinus) is a parrot native to South America. With a length (from the top of its head to the tip of its long pointed tail) of about one meter, it is longer than any other species of parrot. It is the largest macaw and the largest flying parrot species.

Blue AnimalsHyacinth macaws have impressive cobalt blue feathers, which contrast with their bare yellow eye ring (which, in other species of macaw is white) and the yellow patch of skin beside the lower bill. Their irises are dark-brown in color and their feet are dark gray. Females and males are nearly indistinguishable, but the females are typically a little more slender. On juveniles, the upper bill is paler and the tail is shorter.
The Hyacinth macaws are native to central and eastern South America and now inhabit only three distinct areas: the Pantanal, a natural region of Brazil, Bolivia, and Paraguay; The Cerrado, a tropical savanna ecoregion of Brazil; the eastern Amazon Basin of Brazil. Hyacinth macaws are found in palm swamps, woodlands, and other semi-open, wooded habitats. They usually avoid dense, humid forests and often inhabit savannah grasslands, dry thorn forests known as 'caatinga', and palm stands.
Hyacinth macaws are very social birds. They can be seen alone but usually form groups of up to 4 birds. They are also often found in bigger groups of between 12 and 20 birds, which often include pairs and family trios (parents and chick). They feed mainly during the morning and the late afternoon and are sometimes active on moonlit nights. During the heat of the day, they rest in the canopy. Pairs stay close to each other. On being disturbed, they fly out of the canopy to circle over treetops, making their loud calls. They are very noisy birds.
Hyacinth macaws are herbivorous (granivorous, frugivorous) birds. They feed mainly on nuts from specific palm species, such as acuri and bocaiuva palms, and consume a wide variety of seeds and tree fruits.
Hyacinth macaws are monogamous and usually remain with one partner their entire life. They produce one brood per season and don’t breed every year, breeding after the rainy season, which is July to December. They make their nests in cliff faces or tree cavities, depending on what is available. 1 or 2 eggs are laid, the second being several days later than the first. Incubation is done by the female, for about a month, and the male brings her food during this period. Chicks fledge around 4 months after hatching. Often the smaller chick dies, so only one survives. Chicks remain with their parents for around 6 months and both parents feed them. These birds reach reproductive maturity at the age of 7 to 10 years.
Hyacinth macaw numbers are in decline due to the illegal pet trade (being highly prized as pets) and habitat loss. Their habitat is being lost or changed due to cattle ranching and mechanized agriculture, as well as hydroelectric schemes. Some native people hunt these birds for their colorful feathers for use in headdresses or other souvenirs for tourists.
According to the IUCN Red List, the total population size of Hyacinth macaws is 6,500 individuals (including 4,300 mature individuals), of which 5,000 individuals are in the Pantanal region. Hyacinth macaws’ numbers are decreasing today and they are classified as Vulnerable (VU) on the IUCN Red List.
Hyacinth macaws have an important part to play in their ecosystem through the dispersal of nuts and seeds throughout their territory.
