The of mantle and the back Green olive: scapulars of the same colour but some with blue tips; rump and uppertail-coverts bright pale blue, lesser and median coverts greenish oliva-marron; greater coverts bluish green.

The tail of the immature opaque yellow-tipped, the plumage duller than the adult Green (especially below), the iris brown.

The older adult birds sometimes show patches of Turquoise in the plumage, especially in rear of the neck and the breast.


    The Military Macaw (Ara militaris) is so similar to this species, in German are called minor military Macaw (Militaris) and greater (ambiguous).

    An Ecuadorean specimen intermediate between the Great Green Macaw (Ara ambiguus) and the Military Macaw (Ara militaris) suggests one hybridization, increasing the likelihood that the two forms are the same species. Although separate from the ecological point of view.

    The Ambiguous macaws and Military You can be in contact at the bottom of the Valle del Cauca in Colombia, and in the Northwest of Ecuador and West Colombia. The Great Green Macaw (mainly in humid lowland forests) use deciduous forests, While the Military Macaw (mainly of dry upland forest) they are also recorded in lowland moist forests. Both make seasonal movements and in the case of the Military Macaw, they perform movements of long distance between their preferred habitats.

    The length of the tail and of the wings of the Mexican military Macaw and species nominal of the Great Green Macaw, They show a considerable overlap. Waiting to collect more details, the Great Green Macaw and the Military Macaw they are here treated as separate species.

  • Sound of the Great Green Macaw.
Subspecies description:
  • Ara ambiguus ambiguus

    (Bechstein, 1811) – The nominal species

  • Ara ambiguus guayaquilensis

    (Chapman, 1925) – The bill smaller, with a more greenish color under the flight feathers and under the tail.


The Great Green Macaw they are very shy and difficult to see birds, usually found at no lower altitudes of 35 meters in the treetops. They feed in silence and many times could be up to more than five hours in a same tree.

Mainly observed in moist lowland forests, but also in deciduous forests in the Chongon region to the southwest of Ecuador.

In Costa Rica in the primary forest of low and clear land with tall trees, from time to time in the lower montane forests. Crossing open between forest fragments fields and visit remnants of trees of the species Dipteryx on forest pastures.

Remote forests in Panama.

In Ecuador inhabits humid lowland, deciduous forest and Montane forest low but also visit more open areas for feeding.

They come to the 600 metres in the Cordillera de Guanacaste, Costa Rica; between 1.000 and more rarely 1.500 m, in Darien, Panama.

Less sociable than other large macaws, Although usually seen in pairs, in groups of 3-4, and more rarely in groups of up to twelve birds.


Form pairs of lifetime and are almost true to their nests, nesting from December to June. The majority of couples the first egg at the end of January and February the nests are young. The female incubates the eggs, While the male brings food to the nest. Both parents are responsible for feeding the pigeons, to do so approximately every two hours. These are birds that take care of their chicks until they can avail themselves, They even take care of them until that hatch the chicks of the season.

The average clutch consists of 2 – 3 white eggs, they are incubated by the female for a few 26 days. Hatchlings are blind, nude and completely dependent on the care of parents; they weigh around 23 g..

The chicks are fed by both parents and they leave the nest When you have about 12 – 13 weeks of age. At the time they leave the nest, usually weigh between 930-985 g..

A nest in Guayas, Ecuador, in the cavity of a tree of the species Cavanillesia platanifolia. Reported nestings between August-October in Ecuador. Breeding during the dry season (December-April) in Costa Rica.


The diet of the Great Green Macaw includes fruits of Lecythis costaricensis, Dipteryx panamensis, Sloanea, Dalium guianensis and Ficus, and flowers of Symphonia globulifera.

Feeds in the treetops.


Tamaño del área de distribución (reproducción/residente): 100,000 km2

Its distribution ranges from the East of Honduras to western Colombia and West of Ecuador.

Observed in the lowlands of the Caribbean East of Honduras through this of Nicaragua to the lowlands of Costa Rica especially on the slope of the Caribbean, including the Cordillera de Guanacaste.

In Panama especially on the slope of the Caribbean, but also locally in the Pacific. From East Panama to the tropical zone to the West of Colombia, on Western Cordillera of the Andes and South to the upper area of the Atrato river and the The Baudó mountains (possibly up to Buenaventura) and East towards the north end of the Andes in the West of the upper part of the Valley of the Rio Sinú.

In West Ecuador observed mostly from the Colonche hills, Northwest of Guayaquil; also further north, in Esmeraldas, possibly in the extreme southwest of Colombia, Although forests here are, Perhaps, too humid (See geographic variation).

The numbers fluctuate locally due to movements of foraging season. Local appearances in Costa Rica they often coincide with the fruiting of trees of the species Dipteryx.

Local, being the most common of the large macaws in Panama. However, in general, rare, with the decline in recent large scale of its population due to obvious deforestation in the range.

Extinguished much of Ecuador, where the population (only 100 birds) It is threatened by loss of habitat due to urbanization and agriculture.

The exploitation of trees of the species Dipteryx It poses a serious threat in Costa Rica.

They occur in several protected areas, including the The Darien biosphere reserve, Panama, The Rio Platano Biosphere Reserve, Honduras and the Cotacachi-Cayapas ecological reserve, Ecuador, but seasonal pilgrimages suggest that these areas are insufficient on their own to preserve the populations.

Less common that the Military Macaw (Ara militaris) in captivity and bred rarely. CITES Appendix I. VULNERABLE (included as subspecies of the Military Macaw Necklace et to the. 1994).

Distribution of subspecies:
  • Ara ambiguus ambiguus

    (Bechstein, 1811) – The nominal species

  • Ara ambiguus guayaquilensis

    (Chapman, 1925) – In critically endangered; they live in the wild in limited sectors of the western part of the Ecuador; characteristic is their habitat in tropical and dry damp forests of the Ecuadorian coast


• Current red list of UICN: Danger

• Population trend: Decreasing

Recent estimates suggest that the population has less than 2.500 mature individuals (or less than 3.700 in total if we include juveniles and immature); would be the largest sub-population in Darien, to the East of Panama, with less than 1.700 mature individuals (or less than 2.500 in total). You still must be careful, due to that in non-breeding times can form groups of 50 individuals or more, It can be qe will overestimate their populations. In addition, Although it is most abundant in Darien, It is found in specific areas, finding numerous areas without copies.

In captivity:

Less common that the Military Macaw (Ara militaris) in captivity and bred rarely.

The Great Green Macaw only recommended for experienced handlers and breeders. There are more silent than other macaws and can be kept with other large macaws outside the breeding season.

Breeding pairs require long flights of at least 15 m. These parrots are not suitable for the interior of a House.

With regard to its longevity, According to sources, a specimen was still alive after 29 years in captivity.
