Periquito Cachetiverde

Identificación

The green-cheeked parakeet is 25 to 26 cm (9.8 to 10 in) long and weighs 62 to 81 g (2.2 to 2.9 oz). The sexes are the same. Adults of the nominate subspecies P. m. molinae are dull brown from forehead to nape and have green cheeks, ashy brown ear coverts, and a creamy white ring of bare skin around the eye. Their upperparts are green. Their chin, throat, and the sides of their neck are a scaly brown and whitish. Their belly is dull reddish and their lower flanks and vent area are green. Their wing is mostly green, with bluish flight feathers. Their tail is dull reddish. Immatures are similar to adults but without the red belly.<p>Subspecies P. m. phoenicura is green on the upper surface of its tail's base. P. m. restricta has a blue collar, a blue tinge on its cheeks, and a smaller red belly patch than the nominate. P. m. hypoxantha has a paler crown and less distinct scaling on the breast than the nominate. P. m. australis is paler than the nominate and has a larger red belly patch. P. m. flavoptera is orange to red at the bend of the wing and on the carpal edge and is otherwise like the nominate.<p>A small number of individuals of P. m. hypoxantha have mostly yellow underparts.

Taxonomía

The green-cheeked parakeet has these six subspecies:<p>Subspecies P. m. hypoxantha was previously known as P. m. sordida and was sometimes treated as a separate species. However, by the principle of priority the older name hypoxantha replaced sordida. The green-cheeked parakeet has also been treated as conspecific with the maroon-bellied parakeet (P. frontalis).<p>The green-cheeked parakeet is most closely related to the maroon-bellied, pearly (P. lepida), and crimson-bellied (P. perlata) parakeets.

Distribución y hábitat

The subspecies of the green-cheeked parakeet are found thus:<p>The green-cheeked parakeet inhabits lowland woodlands and forest (chiefly deciduous), secondary forest, and gallery forest in the lower elevations of the Pantanal and humid subtropical forest as high as 2,000 m (6,600 ft).

Vertical migration

Comportamiento

The populations of green-cheeked parakeet breeding in higher elevations move to lower ones in winter.<p>The green-cheeked parakeet has a varied diet that, in the wild, consists of fruits, seeds, flowers and, to a lesser extent, nectar and leaves.<p>The green-cheeked parakeet's breeding season in Argentina includes February, but its season elsewhere has not been defined. It nests in tree cavities. In captivity the clutch size is four to six eggs, the incubation period is 22 to 25 days, both sexes incubate the clutch, and fledging occurs about seven weeks after hatch.<p>The green-cheeked parakeet's flight calls "comprise rather high-pitched notes with a grating quality and usually given in fast series, e.g. "krree krree krree", but also single "kuree" notes." From a perch it "utters high-pitched, more melodious notes, such as a bisyllabic "rrekeet" or "keew"." However, perched birds are often silent. Flocks in flight "call frequently and simultaneously, producing a noisy, harsh and piercing chattering."
