'''Parrots''' or psittacines is an [[order (biology)|order]] (namely '''Psittaciformes''') of birds that includes over 350 known [[species]]. They are usually grouped into two [[family (biology)|families]]: the [[Cockatoo|Cacatuidae]] (cockatoo), and the [[true parrots|Psittacidae]] (true parrots). Macaws are members of the true parrots.
 
  
 
Like other parrots, macaws have a generally erect stance and a characteristic curved beak shape with the upper mandible having slight mobility in the joint with the skull. Parrots also are  zygodactyl, having four toes on each foot, with two toes at the front of each foot and two at the back.

Macaws have very long tails, large and strong curved beaks, and usually brilliant plumage. The largest macaw is the hyacinth macaw (''Anodorhynchus hyacinthinus''), which reaches 100 centimeters (almost 40 inches) in head and body length and 1.4 to 1.7 kilograms (3 to 3.7 pounds) in weight, and the smallest is the red-shouldered macaw, which reaches 30 centimeters (11.8 inches) in length and 129 to 169 grams (4.5 to 5.9 ounces) in weight (San Diego Zoo 2007). The hyacinth macaw's wingspan is more than four feet (San Diego Zoo 2007).

Macaws have very long tails, large and strong beaks, and usually brilliant plumage. In terms of length and wingspan, the macaws include the largest birds in the parrot family, although the flightless Kakapo is heavier (Marshall 2006). The largest macaw is the hyacinth macaw (''Anodorhynchus hyacinthinus''), which reaches 100 centimeters (almost 40 inches) in head and body length and 1.4 to 1.7 kilograms (3 to 3.7 pounds) in weight; the smallest is the red-shouldered macaw, which reaches 30 centimeters (11.8 inches) in length and 129 to 169 grams (4.5 to 5.9 ounces) in weight (San Diego Zoo 2007). The hyacinth macaw's wingspan is more than four feet (San Diego Zoo 2007).
  
Macaws eat a variety of fruits, nuts, seeds, flowers, and even insects, and snails. Their powerful beaks allow some species to crush very hard nuts, such as the Brazil nuts (and sometimes even through the metal bars of cages). Some macaws are known to eat clay as an antidote to the toxic chemicals in the seeds or fruits they eat. Scientists have found out that the chemicals in clay mix with the poison allowing it to pass through the bird's [[Gastrointestinal tract|digestive system]] unharmed.

Macaws are known for their beautiful colors. They are also considered to be intelligent.

Macaws are [[monogamy|monogamous]] and usually pair bond until one of them dies. After the eggs are laid, the mother incubates until the chicks hatch while the father brings food. Macaws have a life span of about 50 years, but there are longer lived macaws (Marshall 2006, San Diego Zoo 2007).  
  
Macaws have been said to live for up to 100 years; however, an average of 50 years is probably more accurate. The larger macaws may live up to 65 years.
+
Many species of macaw are associated with forest, especially [[rainforest]], although others prefer woodland or [[savanna]]-like habitats (Marshall 2006). The [[Pantanal]] of Brazil, Bolivia, and Paraguay, known as the world's largest wetland, is home to the blue and yellow macaw (''Ara ararauna''), green winged macaw (''Ara chloroptera''), red-shouldered macaw (''ara nobilis''), and remains one of the best envrironments to see the endangered hyacinthin macaw (''Anodorhynchus hyacinthinus'') (Swarts 2000). Various reports put the scarlet macaw (''Ara macao''), just outside the Pantanal boundaries, but in the state of Mato Grosso, Brazil (Swarts 2000).

The '''Cuban Red Macaw''', ''Ara tricolor'', is an [[extinct]] [[parrot]] that formerly occurred on [[Cuba]] and the [[Isla de la Juventud]]. It was a rather small species of ''Ara'' [[macaw]], measuring 45 - 50 cm. A pair was kept in the royal [[menagerie]] of [[Schönbrunn Castle]], [[Vienna]], from [[1760]]. The Cuban Red Macaw was reasonably common around [[1800]]. During the early [[19th century]], the human population in its home range increased dramatically, leading to widespread deforestation. The bird was also hunted for food, and nests were plundered or disturbed to acquire young birds to keep as pets. Until [[1849]], the species seems to have been able to hold its own at least in remote areas, but subsequently, the population crashed never to recover.

The problem with illegal trafficking in macaws is clear when it is realized that a single hyacinthin macaw can fetch US$6,500 to US$12,000 in the United States (Swarts 2000). In February of 1999, authorities interdicted an effort to smuggle 24 hyacinthin macaw eggs from Sao Paulo, Brazil to Pennsylvania, with the value of the eggs estimated at US$10,000 each (Swarts 2000).

Blue-and-gold Macaw
Scientific classification

Class: Aves
Order: Psittaciformes
Family: Psittacidae
Genera

Ara

Primolius
Orthopsittaca
Diopsittaca

A macaw is any parrot (family Psittacidae) belonging to one of six genera: Ara, Anodorhynchus, Cyanopsitta, Primolius, Orthopsittaca, and Diopsittaca. They are native to Mexico, the Caribbean, and Central and tropical South America, and are known as araras in Portuguese and guacamayos in Spanish.

Macaws are known for their often colorful plumage.

Description

Parrots or psittacines is an order (Psittaciformes) of birds that includes over 350 known species. They are usually grouped into two families: the Cacatuidae (cockatoo), and the Psittacidae (true parrots). Macaws are members of the true parrots.

Like other parrots, macaws have a generally erect stance and a characteristic curved beak shape with the upper mandible having slight mobility in the joint with the skull. Parrots also are zygodactyl, having four toes on each foot, with two toes at the front of each foot and two at the back.

Two scarlet macaws

Macaws have very long tails, large and strong beaks, and usually brilliant plumage. In terms of length and wingspan, the macaws include the largest birds in the parrot family, although the flightless Kakapo is heavier (Marshall 2006). The largest macaw is the hyacinth macaw (Anodorhynchus hyacinthinus), which reaches 100 centimeters (almost 40 inches) in head and body length and 1.4 to 1.7 kilograms (3 to 3.7 pounds) in weight; the smallest is the red-shouldered macaw, which reaches 30 centimeters (11.8 inches) in length and 129 to 169 grams (4.5 to 5.9 ounces) in weight (San Diego Zoo 2007). The hyacinth macaw's wingspan is more than four feet (San Diego Zoo 2007).

Macaws eat a variety of fruits, nuts, seeds, flowers, and even insects and snails. Their powerful beaks allow some species to crush very hard nuts, such as the Brazil nuts (and sometimes even through the metal bars of cages). Some macaws are known to eat clay as an antidote to the toxic chemicals in the seeds or fruits they eat. Scientists have found out that the chemicals in clay mix with the poison allowing it to pass through the bird's digestive system unharmed.

Macaws are monogamous and usually pair bond until one of them dies. After the eggs are laid, the mother incubates until the chicks hatch while the father brings food. Macaws have a life span of about 50 years, but there are longer lived macaws (Marshall 2006, San Diego Zoo 2007).

Many species of macaw are associated with forest, especially rainforest, although others prefer woodland or savanna-like habitats (Marshall 2006). The Pantanal of Brazil, Bolivia, and Paraguay, known as the world's largest wetland, is home to the blue and yellow macaw (Ara ararauna), green winged macaw (Ara chloroptera), red-shouldered macaw (ara nobilis), and remains one of the best envrironments to see the endangered hyacinthin macaw (Anodorhynchus hyacinthinus) (Swarts 2000). Various reports put the scarlet macaw (Ara macao), just outside the Pantanal boundaries, but in the state of Mato Grosso, Brazil (Swarts 2000).

Status

Hyacinth macaw

The majority of macaws are now endangered in the wild. Five species are already known to be extinct, and Spix's Macaw is now considered to be extinct in the wild, and the glaucous macaw is also probably extinct, with only two reliable records of sightings in the 20th century (Marshall 2006). The greatest problems threatening the macaw population are the rapid rate of deforestation and the illegal trapping of birds for the bird trade.

The Spix's macaw (Cyanopsitta spixii), the only member of the parrot genus Cyanopsitta, probably went extinct in the wild around 2000, when the last known wild bird died; however, there is a captive population of some 68 individuals (BirdLife 2006), .

The Cuban Red Macaw, Ara tricolor, is an extinct species that formerly occurred on Cuba and the Isla de la Juventud, and was common in the early 19th century. However, loss of habitat due to widespread deforestation, as well as hunting and plundering of nests for young birds for pets let to its extinction before the 20th century.

The problem with illegal trafficking in macaws is clear when it is realized that a single hyacinthin macaw can fetch US$6,500 to US$12,000 in the United States (Swarts 2000). In February of 1999, authorities interdicted an effort to smuggle 24 hyacinthin macaw eggs from Sao Paulo, Brazil to Pennsylvania, with the value of the eggs estimated at US$10,000 each (Swarts 2000).

Birds in captivity

Parrot in general make popular pets. However, macaws, with their powerful jaws and large amount of intelligence can be difficult pets. They gnaw and chew on various objects and require constant intellectual stimulation to satisfy their innate curiosity. Used to bonding for life with a mate, in captivity unmated macaws will bond primarily with one person–their keeper. Pet macaws thrive on frequent interaction, and a lack of this can lead to their mental and physical suffering.

Captive pet macaws sometimes display difficult behavior, the most common being biting, screaming, and feather-plucking. Feather-plucking does not normally occur in the wild, strongly suggesting that it is the result of a neurosis related to life in captivity.

Most pet macaws had ancestors living in the wild just two or three generations ago, and are not truly domesticated by any reasonable definition. (This is unlike, for example, dogs; some estimates put the domestication of dogs as far back as 40,000 years ago.)

All species of macaws have very powerful, large beaks. Just as they a capable of cracking nuts with those jaws, they can harm fingers and even knuckles of children and adults. They can also be very loud.

International trade in macaws is illegal under the CITES agreement. Only captive born birds may be sold as pets.

A common trend in recent years is hybridizing macaws for the pet trade. Hybrids are typical macaws, with the only difference from true species being their genetics and their colors. For example, a hybrid may be made between Ara ararauna and Ara chloroptera, or between Ara ararauna and Ara macao. As a number of species of macaws are endangered, it would be beneficial to maintain pure breeding stock of captive macaws to ensure species preservation. Hybridizing dilutes the available gene pool and could hasten a species extinction.
