Birdfinding.info ⇒  Locally common in several parts of its natural range along the eastern flanks of the Andes.  In Peru, the distinctive chlorogenys population can be found at several sites in the central Marañon Valley, and typical mitratus is common in Cuzco, including Machu Picchu, Ollantaytambo, and Limatambo.  In Bolivia, it is especially common in Cochabamba.  In Argentina, consistent areas include Calilegua National Park, Yala Provincial Park (Jujuy), the Salta area, and the hills above San Miguel de Tucumán.  Established sites for urban populations include: in the Bay Area, Las Palmas Park, Sunnyvale; in Los Angeles, South Pasadena, Entradero Park, Belmont Heights, and downtown Orange; in southern Florida, downtown Fort Lauderdale, Miami Springs, and throughout Kendall; in Buenos Aires, Parque Pereyra; and in Barcelona, Parc Güell and Parc de la Ciutadella.

Mitred Parakeet

Psittacara mitratus

Andes of Peru, Bolivia, and Argentina; introduced elsewhere.

Approximate natural range of the Mitred Parakeet.  © BirdLife International 2018

Native to eastern slopes of the Andes from northern Peru south to northwestern Argentina, where it occurs in humid forests, edges, and partly wooded habitats at elevations that span approximately 1,000 to 3,500m.

Range is somewhat discontinuous, with significant population centers in four disjunct areas: (1) the distinctive, isolated subspecies chlorogenys in northern Peru (southern Amazonas and northern San Martín); (2) central Peru from Huanuco to Cuzco; (3) central Bolivia from La Paz to Santa Cruz; (4) southernmost Bolivia to Catamarca, Argentina.

Introduced urban populations are established in: the Bay Area and Los Angeles, California; southeastern Florida; Buenos Aires and La Plata, Argentina; and Barcelona, Spain.  Smaller populations are more tenuously established around Lima and Arequipa, Peru.

In Hawaii, an introduced population on eastern Maui grew to over 200 during the 1990s, but it became the focus of a control program, and only a few remained into the 2010s.  Starting in the late 1990s, small flocks have occasionally been observed on the Big Island along the Kona Coast.

Identification

Confusingly variable and similar to several related species.  A large, green parakeet with a large ivory or off-white bill, a broad whitish eyering of bare skin, a red forehead, and variable amounts of red on the face that usually extend below and behind the eye and in irregular patches elsewhere on the head.  It usually has smaller flecks of red scattered elsewhere on the neck and underparts, and sometimes on the back and wings.

Much of the variation follows a geographical pattern in which northern populations (especially the northernmost, chlorogenys of northern Peru) have mostly green heads with red mostly on the forehead, and southern populations (especially the southernmost, tucumanus of northwestern Argentina) have more extensive red.  In the latter populations some individuals have mostly red heads.

All populations tend to have irregular, blotchy patches and scattered flecks of red that can appear almost anywhere on the body.

Immatures can have little or no red on the face, or red limited to the forehead, and are potentially mistaken for several closely related species that may occur with it in areas where it is introduced.

The wings tend to be all-green—depending on the lighting, the underwing may appear brownish-olive or yellowish.  Some individuals, especially in southern populations, have some red on the wings, usually on the leading edge.

Voice.  Typical calls include nasal creaks and harsh screams:

Cf. Cordilleran Parakeet.  In the Marañon Valley of northern Peru, two extremely similar populations of Psittacara parakeets occur together: chlorogenys (an atypical subspecies of Mitred) and minor (Cordilleran, which is often classified as a form of Scarlet-fronted).  Both populations have approximately the same distribution of red on the head and neck—both have the typical Cordilleran pattern, which is not typical of other Mitred or Scarlet-fronted.

The only consistent difference between them is that minor (Cordilleran) typically shows red on the leading edge of the wing, most noticeable in flight from below, whereas chlorogenys (Mitred) has a uniformly green underwing—depending on the lighting, it can also appear brownish-olive or yellowish, but not red.

In context, knowing that both populations look like Cordilleran but differ in wing markings, their identification is straightforward.  In this case the confusion is due mainly to inconsistent species-level classification of the populations, and the fact that these overlapping populations resemble one another more than they resemble distant populations that are often assigned to the same species.

Cf. Red-masked Parakeet.  Their natural ranges are not known to overlap, but introduced populations of Mitred and Red-masked Parakeets occur together in several cities.  Mitred has highly variable plumage, an inherently confusing species, whereas adult Red-masked has a consistent pattern.  Immature plumages of the two species can be essentially identical, and are usually identifiable only by their association with adults.

Adult Red-masked is distinguished by its contiguous red hood, which tapers toward the chin.  The red area sometimes has a rough border and a few stray specks, but usually gives a helmet-like impression.  Mitred can show essentially the same amount of red on the head, but its distribution is blotchier, with scattered specks of red over a wider area.  Red-masked shows red on the shoulder of the folded wing and a distinct red bar on the leading edge of the underwing, where Mitred shows little or no red.

Voice can be a useful clue.  Mitred and Red-masked have similar repertoires, but Red-masked’s calls tend to be higher-pitched: its nasal creaking has a jay-like quality and its screams are thin and piercing.  Mitred’s nasal creaking is mellower and its screams are harsher, less shrill than Red-masked’s.

Cf. Other Psittacara Parakeets.  In areas where it is introduced, Mitred is easily confused with various other members of its genus, both immature and adult plumages.

Notes

Polytypic species consisting of four currently recognized subspecies: chlorogenys of northern Peru; alticola of upper elevations in southeastern Peru and possibly western Bolivia; mitrata of central Peru to northwestern Argentina; and tucumanus of northwestern Argentina.

Alticola has at times been recognized or proposed as a distinct form or species (either Chapman’s Parakeet or Mountain Conure), but there seems to be little evidence that it exists as a recognizable population.  Another putative species, Hocking’s Parakeet (P. hockingi), is generally thought to represent an immature plumage of Mitred.
