Taxonomic note
Aratinga holochlora (Sibley and Monroe 1990, 1993) was previously split into A. holochlora, A. brevipes, A. rubritorquis and A. strenua following Stotz et al. (1996), contra AOU (1998). Following a review by the BirdLife Taxonomic Working Group (BTWG), A. brevipes and A. rubritorquis are retained as species contra AOU (1998), but A. strenua has been lumped with A. holochlora contra AOU (1998). The BTWG recognises A. rubritorquis and A. brevipes as species separate from A. holochlora for the reasons given in Howell and Webb (1995); (for brevipes see also Collar 1997 and Juniper and Parr 1998). For rubritorquis and holochlora, the assortative behaviour reported in a mixed roost, largely parapatric distributions, and the (albeit relatively minor) morphological differences are considered sufficient to warrant their separation, pending further study. For brevipes and holochlora, the BTWG acknowledges that the morphological differences are relatively minor but finds the report that their voices are "notably different" (Howell and Webb 1995) more persuasive, and separates them pending a rigorous vocal review and analysis. The taxon strenua is treated as a subspecies of A. holochlora following Forshaw (1989), who found that the two forms intergrade in all measurements and concluded that "strenua is nothing more than a poorly differentiated race", a view supported by Juniper and Parr (1998).
