Rotmaskensittich

Bestimmung

The mitred parakeet is 31 to 38 cm (12 to 15 in) long and weighs 219 to 275 g (7.7 to 9.7 oz). The sexes are alike. Adults of all subspecies are mostly green with a purplish forehead and a variable amount and pattern of red on the face. All subspecies have a red forecrown and red in front of their eye. The red usually extends past the eye and down the cheeks, and is often just flecks on the ear coverts. Subspecies P. m. chlorogenys has less red around and below the eye than the others, often a blue tinge on the crown, and some red on the thighs. Some individuals of all subspecies have a small amount of red at the bend of the wing. Their eye is surrounded by bare white skin and their bill is horn colored. Juveniles have little or no red.<p>The differences in plumage coloration noted in the field and in specimens are possibly due to erroneous age assignments, and might also be clinal.

Taxonomie

The mitred parakeet was for a time placed in the genus Aratinga but from about 2013 has been in its present genus Psittacara. Its taxonomy is otherwise unsettled. The International Ornithological Committee (IOC) recognizes these three subspecies:<p>The American Ornithological Society (AOS) and the Clements taxonomy recognize a fourth subspecies, P. m. alticola ("Chapman's parakeet"), that Arndt (2006) had suggested as a separate species. Agnolin (2009) called into question the validity of P. m. tucumanus, and BirdLife International's Handbook of the Birds of the World (HBW) does not recognize it or P. m. alticola, assigning only P. m. chlorogenys and P. m. mitratus to the mitred parakeet.<p>Arndt (2006) also suggested that another full species, P. hockingi ("Hocking's parakeet"), exists within the mitred parakeet. The IOC, AOS, Clements, and HBW have not accepted this taxon as either a species or subspecies.<p>This article follows the three-subspecies model.

Verbreitung und Lebensraum

The nominate subspecies P. m. mitratus of the mitred parakeet is found from the departments of Ayacucho and Cuzco in Peru south through Bolivia into northwestern Argentina as far as Córdoba Province. Subspecies P. m. chlorogenys is found on the eastern slope of the Peruvian Andes between Amazonas and Junín departments. P. m. tucumanus is found in the Argentinian provinces of Córdoba and Tucumán.<p>The mitred parakeet has been introduced to Uruguay and is established there. Populations in California, Florida, and Hawaii are apparently derived from escaped or released cage birds. California's official list does not include the species but the other two states' lists do.<p>In their native range mitred parakeets inhabit a variety of landscapes, most of them forested. These include both evergreen and deciduous montane forest, cloudforest, secondary forest, and semi-humid to humid scrub areas in otherwise arid zones. In elevation subspecies P. m. chlorogenys ranges from 1,200 to 2,900 m (3,900 to 9,500 ft). The other two suspecies occur in the wider elevational range of 1,000 to 3,400 m (3,300 to 11,200 ft) with one reported sighting at 4,000 m (13,000 ft) in Peru. The introduced populations in California and Florida mostly occur in suburban and urban areas while those in Hawaii occur in both populated and unpopulated areas.
