Plain Parakeet

The plain parakeet is 23 to 25 cm (9.1 to 9.8 in) long and weighs about 63 g (2.2 oz). Adults have an essentially all green body, though their nape has a bluish tinge and their undersides have a yellowish one. Their shoulder is bronzy or brownish green and their flight feathers and the underside of their tail are bluish green. Their bill is pinkish with a paler base. Immature birds are similar to adults but with less blue in the wings and a shorter tail. The population in São Paulo state has many individuals with a blue mutation.

The plain parakeet is found in eastern Brazil from Alagoas south to Santa Catarina with an isolated population in Rio Grande do Sul. It inhabits the Atlantic Forest biome, where it occurs in secondary forest, cultivated land with groves of trees, plantations, and urban parks. It is common in cities "including the huge metropolises of Rio de Janeiro and São Paulo". Towards the higher elevations inland it also is found in the edges and canopy of montane rainforest. In elevation it is mostly in the lowlands but can be found as high as 1,200 m (3,900 ft).

A plain parakeet feeds mainly on seeds, fruit, flowers, and nectar from a very wide variety of plants and trees. It also takes some adult and larval insects.
