Mitred Parakeet

Characterized by its medium to large size within the family, this taxon displays a total length ranging from 34 to 38 centimeters and a body mass of approximately 150 to 200 grams. The plumage is predominantly a bright green color, appearing slightly paler and more yellowish on the underparts of the body. The most striking diagnostic feature is a vibrant scarlet-red facial mask covering the forehead, lores, cheeks, and periocular area, often accompanied by scattered red feathers on the neck, flanks, and thighs. It features a prominent, bare creamy-white orbital ring that surrounds an iris ranging in color from yellow to orange. The robust, hooked bill is pale horn-colored, while the feet are grayish. Juvenile individuals are distinguished by having significantly less red on the head, which gradually increases through successive molts as they reach maturity.

Geographical distribution: It is natively distributed along the eastern slopes of the Andes Mountains, extending from central and southern Peru, through western Bolivia, to northwestern Argentina, particularly in the provinces of Salta, Jujuy, Tucumán, and Catamarca. Furthermore, as a consequence of accidental releases and deliberate escapes from the pet trade, the species has successfully established viable, self-sustaining feral populations in urban and suburban areas of California, Florida, and Hawaii in the United States, as well as in major South American metropolitan areas such as Lima and Buenos Aires.

Habitat: This bird primarily occupies temperate and subtropical montane zones and inter-Andean valleys, spanning an elevational gradient from 1000 to 3400 meters above sea level, occasionally reaching up to 4000 meters. It is a characteristic inhabitant of humid montane forests, also known as Yungas, deciduous woodlands, semi-arid shrublands, and adjacent agricultural areas. Additionally, it exhibits remarkable ecological plasticity, successfully colonizing urban parks and residential gardens where it exploits human-modified landscapes for nesting sites and year-round food resources.

Feeding: It is an opportunistic herbivore with a diet specialized in a wide variety of plant matter. Its feeding spectrum encompasses seeds, fruits, berries, flower buds, and blossoms of native species, including those of the genus Podocarpus and various cacti. In agricultural and peri-urban zones, it frequently invades cultivations of maize, figs, citrus fruits, and walnuts, sometimes causing notable damage to local crops and leading to conflicts with farmers. It utilizes its powerful beak as a third limb to climb and dexterously manipulate food items before consumption.

Behavior: Highly gregarious and intensely social, this species typically travels in noisy flocks that can range from a dozen to over a hundred individuals. Flight is swift and direct, characterized by shallow, rapid wingbeats and accompanied by loud, screeching calls that maintain group cohesion. It forms large communal roosts on vertical cliff faces or in the canopy of tall trees, dispersing at dawn toward feeding grounds. Seasonal altitudinal migrations are performed in response to resource availability and harsh winter weather in higher mountain ranges.

Nesting: The breeding season generally takes place between November and March, aligning with the peak abundance of food resources. It is a monogamous species that forms long-term pair bonds. It nests in deep cavities located in vertical rock cliffs, clay banks, or hollows of mature trees. The female lays a clutch of 2 to 4 white eggs, which she incubates exclusively for 23 to 26 days while the male provides food. Both parents actively feed the chicks via regurgitation until the young fledge, a process that takes around 50 to 60 days after hatching.

Conservation status: It is currently classified as Least Concern (LC) on the IUCN Red List. Although the global population is considered stable and the species occupies a vast geographical range, it faces localized threats. These include habitat loss and fragmentation within Andean forests due to agricultural expansion, alongside the illegal pet trade, which historically targeted this species and inadvertently facilitated its establishment as an exotic breeding bird in several urban centers worldwide.
