    (Salvadori, 1891) – Similar to the species nominal but the males with the rump pale blue; underparts and facial area more yellowish; undertail, the tail more bluish.

  • Forpus xanthopterygius flavescens

    (Hellmayr, 1929) – Generally paler and more yellowish which the nominal. Front, throat and cheeks males, yellow.

  • Forpus xanthopterygius xanthopterygius

    (Spix, 1824) – The nominal

  • Forpus xanthopterygius crassirostris

    (By Taczanowsk, 1883) – As the species nominal but blue pale with emerald green in it forecrown. Primary coverts pale, of color grisaceo-violeta that contrast with the coverts more large of color blue more dark. Upper mandible laterally compressed in the Center.

    Algunos autores como (Stotz et al., 1996, Collar 1997) han seguido a Pinto (1945) y considerado a esta subespecie como especie monotípica bajo el nombre científico Forpus crassirostris

Habitat:

Frequent habitats woodlands more dry such as Open forests and riparian, closed and caatinga; at the edge of the range that is located in the Savannah, palm groves, scrub semiarid and pastures. In the Amazon Western seems to be mainly distributed along the rivers in a growth riparian more light. Mainly in the land low, but reported to 1,200 m in the mountains of the southeast of Brazil. Gregarious, in herds of up to 50.

Reproduction:

It nests, mainly, in the cavities of trees, Although also termite tree, posts in fences, nests Rufous Hornero (Furnarius rufus), which can be occupied by force and lined with grass stalks, or even nests of the Red-rumped Cacique (Cacique haemorrhous). Clutch 3-7 eggs.

Food:

Its diet includes fruit of Cecropia, seeds of Mikania and Trema micrantha and flowers of Ambrosia and Marcgravia; Forages in open areas, sometimes in land.

Distribution:

Tamaño del área de distribución (reproducción/residente): 5.780.000 km2

Its distribution is discontinuous in South America, since the Basin Amazon to the North of Argentina with people separated in the North of Colombia. This last occurs in the lands low in the Caribbean arid from Cartagena through the valley bottom of the river Magdalena South to North of Bolivar and East to the base of Sierra Nevada de Santa Marta. The species reappears in the end South of Colombia about Leticia and possibly in the Putumayo, and records from the Northeast borders of the Ecuador and from the East of Peru to the East of Bolivia in Beni and Santa Cruz; It extends through the basin of the Western Amazon of Brazil eastward to the East of Amazon and in large part of the interior of the this of Brazil towards the Southeast, possibly up to Rio Grande do Sul.

Apparently absent from parts of the East and northeast of Brazilian Amazon with its northeastern limits in Maranhão and Ceará.

Are distributed in the northeast of Argentina, in Missions, Northeast of Currents, Chaco oriental and Formosa Eastern.

Is located in the East of Paraguay and can be observed over the West in the Chaco.

Apparently introduced in Jamaica, but the current situation is unknown.

Mainly resident Although migrant altitude in the southeast of Brazil, with seasonal movements in Argentina in relation to food supply. Common in the East of the cordillera, sometimes locally abundant (for example, in the northern parts of Bay), less abundant in the West, being rare and local (Perhaps reducing) in the Northwest of Colombia and scarce throughout the East of Peru and Bolivia. Perhaps increasing in parts of the Amazon Western with cleared of forest dense, but probably in decline in Paraguay, where previously was common and now rare.

The Blue-winged Parrotlet have been caught for the trade, with captive birds out of those countries in the area of distribution. Is unlikely that the trade has been affected to their abundance in the Middle wild.

Distribution of subspecies

With the aim of preserving the stability of the nomenclature, It has designated a lectotype for the name widely used xanthopterygius, What makes the correct name for the species present. Four subspecies currently recognized.

  • Forpus xanthopterygius flavescens

    (Salvadori, 1891) – Bolivia and Southeast Peru.

  • Forpus xanthopterygius flavescens

    (Hellmayr, 1929) – Maranhão, Piauí, Ceará and Northeast South of Brazil to the North of Bay.

  • Forpus xanthopterygius xanthopterygius

    (Spix, 1824) – The nominal

  • Forpus xanthopterygius crassirostris

    (By Taczanowsk, 1883) – West Amazon in South Colombia, East of Ecuador and this from Peru to center of Amazon, Brazil.

Conservation:

• Current red list category of the UICN: Least concern.

• Population trend: Stable.

Justification of the population

The size of the world's population of the Blue-winged Parrotlet It has not been quantified, but this species is described as “common” (Stotz et to the., 1996).

Justification of trend

Suspected that the population is stable in absence of evidence of any decline or threatens substantial.

In captivity:

In captivity they are not very frequent. They are birds enable you require a large cage. Quiet and something timid. Not is easy to accommodate them with other parrots.
Can be prone to it Obesity.

Note:

Among the various species of the Blue-winged Parrotlet (Forpus xanthopterygius), There is, Unfortunately, a very extensive variety of colors mixed due to the crossing in captivity of the nominal species with several of their subspecies, as well as the different crossings between subspecies. Therefore, is quite doubtful to find still species and subspecies properly colored, especially in the poultry raising European. Only the subspecies Forpus xanthopterygius flavescens, as pure subspecies, is still fairly easy for recognizing.
