Chromosomes obtained from feather tissues of 14 species of Brazilian Psittacidae were analyzed by Giemsa conventional staining and the karyotypes of Ara chloroptera, Propyrrhura maracana and Nandayus nenday are presented for the first time. The remaining species showed no chromosome differences when compared with previous literature data. Two basic karyotype patterns were observed. A karyotype pattern is mostly characterized by biarmed macrochromosomes, while in the other one most macrochromosomes are telocentrics.
