Santarem Parakeet

The Santarém parakeet (''Pyrrhura amazonum''), also known as Hellmayr's parakeet or in aviculture as Hellmayr's conure or the Santarém conure, is a species of parrot in the family Psittacidae. It is found in the eastern and central sections of the Amazon basin south of the Amazon River, only just extending onto the northern bank of this river.

Taxonomy

There are three subspecies recognized by the International Ornithological Congress:

* ''P. a. amazonum'' Hellmayr, 1906 - north of the Amazon River between Monte Alegre and Obidos, south of the Amazon between the Tapajós and Tocantins rivers
* ''P. a. pallescens'' Miranda-Ribeiro, 1926 (previously ''P. a. snethlageae'') - Madeira River basin in southwest Brazil and northern Bolivia
* ''P. a. lucida'' Arndt, 2008 - in the vicinity of the Teles Pires and Cristalino Rivers, in Mato Grosso

It has typically been considered a subspecies of the painted parakeet. While reviewing this group, Joseph (2002) discovered that an undescribed population existed in central Brazil (later also found in north-eastern Bolivia). It was described as ''Pyrrhura snethlageae'' (Joseph and Bates, 2002). No diagnostic difference was found between the taxa ''amazonum'' and ''microtera''; it was therefore recommend that the latter should be considered a junior synonym of the former. As with most other taxa of the ''Pyrrhura picta'' complex, it was recommended that ''amazonum'' should be recognized as a monotypic species, ''P. amazonum'', instead of a subspecies of ''P. picta''.

Ribas ''et al.'' (2006) confirmed by mtDNA that ''P. amazonum'' should be considered a species separate from ''P. picta'' (otherwise, ''P. picta'' would be paraphyletic), but also showed that ''snethlageae'' was very close to, and arguably better considered a subspecies of, ''P. amazonum'' (as already had been expected due to a number of intermediate specimens suggesting that hybrids occur). Consequently, SACC voted to recognize ''P. amazonum'' as a species with ''snethlageae'' as a subspecies. Arndt (2008) described yet another taxon from this complex, ''lucida'', as a subspecies of ''P. snethlageae'', but under the taxonomy used by the IOC, it becomes a subspecies of ''P. amazonum''. The taxonomic status in relations to Deville's parakeet remains unclear.

In 2016, a review of names found ''snethlageae'' to apply to a previously-described subspecies, ''pallescens'', and to thus be synonymous with that subspecies. This synonymization was followed by the IOC.

Description

Total length c. . As other members of the ''Pyrrhura picta'' complex, it is a long-tailed mainly green parakeet with a dark red belly, rump and tail-tip (tail all dark red from below), a whitish or dull buff patch on the auriculars and bluish remiges. The cheeks and ocular region are dark maroon. The nominate subspecies (''P. a. amazonum'') has a narrow blue forehead-band and pale grey scaling to the chest. The remaining subspecies, ''P. a. snethlageae'' and ''P. a. lucida'', have little or no blue to the forecrown and their chests are, uniquely for the ''P. picta'' complex, overall pale with relatively narrow, dark pointed markings. ''P. a. lucida'' is slightly smaller and paler than ''P. a. snethlageae''. Some ''P. a. snethlageae'' have a yellowish eye-ring (the basis for this variation remains unknown), but it is more commonly dark grey as in the remaining subspecies. All subspecies have dark greyish legs.

Habitat and behavior

It is restricted to Brazil and Bolivia. It occurs in tropical humid lowland forest and adjacent habitats. It is social and typically seen in pairs or groups. It feeds on fruits, seeds and flowers. The nest is placed in a tree cavity. It is fairly common in most of its range and occurs in several protected areas, e.g. ''P. a. amazonum'' occurs in the Amazônia National Park, Pará, Brazil, while ''P. a. lucida'' occurs in the Cristalino State Park, Mato Grosso, Brazil.
