About Brotogeris tirica (Gmelin, 1788)
The plain parakeet (Brotogeris tirica (Gmelin, 1788)) measures 23 to 25 cm (9.1 to 9.8 in) long and weighs approximately 63 g (2.2 oz). Adult plain parakeets have a mostly entirely green body, with a bluish tinge on the nape and a yellowish tinge on the undersides. The shoulder is bronzy or brownish green, while the flight feathers and the underside of the tail are bluish green. The bill is pinkish with a paler base. Immature birds resemble adults, but have less blue on the wings and a shorter tail. Many individuals from the population in São Paulo state have a blue mutation.
The plain parakeet is distributed across eastern Brazil, ranging from Alagoas south to Santa Catarina, with an isolated population in Rio Grande do Sul. It lives in the Atlantic Forest biome, and can be found in secondary forest, cultivated land with tree groves, plantations, and urban parks. It is common in cities, including the large metropolises of Rio de Janeiro and São Paulo. At higher elevations inland, it also occurs in the edges and canopy of montane rainforest. Most of its range is in lowlands, but it can be found at elevations up to 1,200 m (3,900 ft).
