Ara is a

extinct species.[1] The genus name was coined by French naturalist Bernard Germain de Lacépède in 1799. It gives its name to and is part of the Arini, or tribe of Neotropical parrots. The genus name Ara is derived from the Tupi word ará, an onomatopoeia
of the sound a macaw makes.

The Ara macaws are large striking parrots with long tails, long narrow wings and vividly coloured

Taxonomy

The genus Ara was erected by the French naturalist

monotypic
and are morphologically and behaviourally different, whereas the three Primolius macaws are green and smaller.

There are eight surviving species, two extinct species that died out during modern times, and a third extinct species known only from

subfossil remains.[1] The last confirmed sighting of the extinct Cuban macaw was in 1864 when one was shot. Several skins of the Cuban macaw are preserved in museums, but none of its eggs have survived.[6]

Several

hypothetical extinct species
of the genus Ara have been postulated based on very little evidence. They may have been distinct species, or familiar parrots that were imported onto an island and later presumed to have a separate identity.

Morphology and appearance

Like the rest of the genus the wings of the blue-and-yellow macaw are long, as is the tail

The Ara macaws are large parrots ranging from 46–51 cm (18–20 in) in length and 285 to 287 

green-winged macaw
have a predominantly horn coloured upper mandible and a black lower one.

The colours in the plumage of the Ara macaws are spectacular. Four species are predominantly green, two species are mostly blue and yellow, and three species (including the extinct Cuban macaw) are mostly red. There is no sexual dimorphism in the plumage, and the plumage of the juveniles is similar to adults, although slightly duller in some species.[7]

Distribution and habitat

The Ara macaws have a

extirpated from Trinidad in the 1960s[8] (but was later reintroduced),[9]
and several hypothetical species apparently became extinct in the islands of the Caribbean.

The Ara macaws are generally fairly adaptable in their habitat requirements; this reaches its extreme in the scarlet macaw, which as suggested in its widespread distribution, uses most habitat types from humid

savannah. The only requirement is sufficient large trees, which is where they obtain their food and breeding holes. The other species are slightly more narrow in their habitat choices, but the need for large trees is universal. The blue-throated macaw generally inhabits forest "islands" in the savanna, and the red-fronted macaw prefers arid scrub and cactus
woodland.

Within their range, birds may travel widely seasonally in search of food. They do not undertake large scale migrations, but instead more local movements amongst a range of different habitats.

Feeding and diet

Like all macaws and most parrots,

green-winged macaws in Venezuela they shared many of the same trees as bearded sakis, although in some cases they ate the seeds at an earlier stage of ripeness than the sakis, when they contained more poison.[10] Macaws, like other parrots, may consume clay to absorb toxic compounds produced by some poisons.[11] As well, the toxic compounds of some foods may be neutralized by compounds, such as tannins
, found in other foods consumed at the same time.

Breeding

Like almost all parrots, the Ara macaws are cavity

green-winged macaw will also nest in natural fissures in cliffs. This nesting habitat is the only one used by the red-fronted macaws, as large enough trees are absent in its arid range.[13]

Macaws are known to have been transported between the

Saint Croix macaw (Ara autochthones) is only known from subfossils, and the Lesser Antillean macaw (Ara guadeloupensis) is known from subfossils and reports.[21][23] No endemic Caribbean macaws remain today, and they were likely all driven to extinction by humans, some in historic, and others in prehistoric times.[24]

In addition to the three species known from remains, several hypothetical extinct Ara macaws were only based on contemporary accounts, but are considered dubious today. Many of these were named by

Walter Rothschild in the early 20th century, who had a tendency to name species based on little tangible evidence.[6] Among others, the red-headed macaw (Ara erythrocephala) and Jamaican red macaw (Ara gossei) were named for accounts of macaws on Jamaica, the Martinique macaw (Ara martinicus) was from Martinique, and the Dominican green-and-yellow macaw (Ara atwoodi) was supposed to come from Dominica.[25]

Other species have been mentioned as well, but many never received

junior synonyms of other species.[26] Woods and Steadman defended the validity of most named Caribbean macaw species, and believed each Greater and Lesser Antillean island had their own endemic species.[24] Olson and Maíz doubted the validity of all the hypothetical macaws, but suggested that the island of Hispaniola would be the most likely place for another macaw species to have existed, due to the large land area, though no descriptions or remains of such are known. They suggested such a species could have been driven to extinction prior to the arrival of Europeans.[21] The identity and distribution of indigenous macaws in the Caribbean is only likely to be further resolved through palaeontological discoveries and examination of contemporary reports and artwork.[27][28]
