Taxonomy and Distribution
Traditionally, the Painted Parakeet included the Santarém Parakeet (P. amazonum), Bonaparte's Parakeet (P. lucianii) and Rose-fronted Parakeet (P. roseifrons) as subspecies. Following a review in 2002, it was recommended treating these as separate species. In 2006, a study based on mtDNA confirmed that the "traditional" Painted Parakeet was polyphyletic, as P. p. picta was closer to the taxon emma (traditionally considered a subspecies of the White-eared Parakeet, P. leucotis) than it was to amazonum and roseifrons. The taxon lucianii was not sampled, but based on plumage and biogeography it likely falls between P. amazonum and P. roseifrons. In 2002 it had also been recommended treating the Azuero Parakeet (P. eisenmanni), Sinú Parakeet (P. subandina) and Todd's/Perijá Parakeet (P. caeruleiceps) as separate species. Of these, only eisenmanni was sampled in 2006, where it, although with low bootstrap support, was found to be relatively close to P. p. picta, and arguably should be retained as a subspecies of the Painted Parakeet. Based on plumage and biogeography, caeruleiceps and subandina are likely also part of this group. Consequently, the South American Classification Committee voted for treating these as subspecies of the Painted Parakeet. Following this treatment, the Painted Parakeet includes the following subspecies:
- P. p. picta (nominate): North-eastern Brazil (north of the Amazon River and east of the lower Rio Negro/Rio Branco, though crossing west of the latter in northern Roraima), the Guianas and south-eastern Venezuela.
- P. p. emma (Venezuelan or Emma's Parakeet): Western Venezuelan Coastal Range.
- P. p. auricularis (Venezuelan Parakeet): Eastern Venezuelan Coastal Range.
- P. p. caeruleiceps (Todd's or Perijá Parakeet): Perijá Mountains in Colombia and Venezuela, and the eastern slope of Magdalena Valley (= western slope of Cordillera Oriental) in Colombia.
- P. p. subandina (Sinú Parakeet): Sinú Valley in Córdoba, Colombia.
- P. p. eisenmanni (Azuero Parakeet): Azuero Peninsula, Panama.
Nevertheless, the possibility that some of the above are separate biological species cannot be discounted at present. It has been suggested that auricularis should be considered a synonym of emma, but a recent review has suggested that auricularis is valid, and consequently it has tentatively been included here. Another taxon, pantchenkoi, has often been considered a valid subspecies or rarely even a separate species, but recent opinion is that it is a synonym of caeruleiceps.

Famous quotes containing the word distribution:
“My topic for Army reunions ... this summer: How to prepare for war in time of peace. Not by fortifications, by navies, or by standing armies. But by policies which will add to the happiness and the comfort of all our people and which will tend to the distribution of intelligence [and] wealth equally among all. Our strength is a contented and intelligent community.”
—Rutherford Birchard Hayes (18221893)
