It is in this family that we find the macaws, parrots, parakeets, jandaias, maracanas, tuims, lovebirds, etc.. Worldwide, species are distributed throughout the tropical area of the globe (Neotropical, Afrotropical, Oriental and Australian) and radiate out to the subtropical and cold. Brazil is the richest country in the world in terms of this family, and has from smaller specimen,s as tuim with 12 cm, to the most representative, as the blue macaw with 1 m in length. At the time of discovery of our land, this surplus was already reported, being our country designated as "Land of Parrots" (Brasilia sive terra papagallorum).
The main characteristics of these species are a large and robust head that supports a strong, long and curved beak, expert in breaking and peel seed. To assist in handling these seeds, they have jaw and tongue muscles very well developed. They have short legs but very articulated, which in addition to sustaining the body of animals, assist in the handling of food they consume. Both males and females have beautiful plumage with exuberant colors, giving them an unparalleled beauty. Usually the sexes are very similar.
This family consists of 78 genera (division within the family), which are distributed in 332 species of psittaciformes. Studies conducted in 1994 show that 86 of these species are critically close to extinction and another 36 threatened with extinction if measures are not taken. Brazil alone is home to about 84 species distributed in 24 genera
