    Habitat:

    It inhabits in Highlands with mature pine forests or pine with other conifers in the genus Pseudotsuga, malls Populus and/or trees of the genus Quercus, in areas isolated and often rugged, sometimes are also observed in towns of lowlands.

    Most are distributed at altitudes between 1,500 and 3,000 m, making breeding usually at heights between 2,000 and 3,000 m.

    Its preference they are areas with Pinus arizonica and Pinus ayacahuite. In general, observed in flocks. They rest in large groups on inaccessible cliffs or trees with dense foliage. Diurnal movements of up 40 km between resting areas and feeding.

    Long-lived and gregarious, they form social groups; because of this, over time the Thick-billed Parrot they return to visit forests which are of your choice.

    Reproduction:

    Nest in the cavities of trees, usually pine, but also, According to sources, in trees of the species Populus tremuloides and Pseudotsuga taxifolia; usually in trees partially dead or alive, with small holes excavated, for example, by woodpeckers as the Northern Flicker (Colaptes auratus) or caused by fungal decomposition in the Heartwood wood; sometimes very together (in the same tree) When there is available room, Although generally scattered.

    The breeding season coincides with the ripening of the pine seeds; birds, generally speaking, they reach the breeding area between the months of April and may, carrying out the mid June to end of July update. The young begin to leave the nest from early September to late October, After 59 – 65 days, Depending on their parents for a period of time after feather.

    Clutch of 2 to 4 eggs, generally three, Perhaps variable with the size of the harvest of pine seeds. Care of eggs during the incubation is performed by the female and the care of the offspring is biparental.

    Food:

    Diet Thick-billed Parrot It is mainly composed of pine seeds (including the of the Pinus teocote and of the Pinus leiophylla) extracted from cones with their powerful beaks; They also feed, According to sources, of seeds and sprouts Conifer Pseudotsuga, fruits of the American black cherry (Prunus serotina) and acorns.

    Distribution:

    The distribution Master of the Thick-billed Parrot lies between the West and centre of Mexico, with sporadic movements towards the North and towards South.

    You can see in Sierra Madre Occidental in the South of Chihuahua, South and West of Durango, the adjacent areas of the East of Sonora and Sinaloa; confirmed breeding only in the first two States.

    Like other bird specialists in pine seeds, the Thick-billed Parrot wanders widely after playback, sporadically to South-West of Mexico and Jalisco, Colima and Michoacán, previously to the East up to Veracruz (Although these records are possibly involved the Maroon-fronted ParrotRhynchopsitta in terris) and, possibly, Coahuila de Zaragoza.

    Formerly it was a sporadic visitor, and possibly resided and lesson in Arizona (especially in the mountains of Chiricahua, in the South) and in New Mexico, EE.UU, Although since the beginning of the century 20 not observed visits on a large scale and date back to the last reproductive data in the area of the 1938.

    The presence of the Thick-billed Parrot is determined by the availability of pine seeds; the core of their playback area It seems to be the most constantly occupied area.

    The decrease important in your population during the century 20 as a result ,mainly, of the loss and degradation of habitat, with the absence of these birds where the large pines were cut down, mainly by forestry. The loss of birds in EE.UU. was attributable to the hunt, but his presence there, probably, It was only in the short term, When were feeding conditions unusually favorable (or on the contrary very unfavorable in Mexico).

    The recent threats in Mexico they are the trade in live birds and the continuous loss of habitat for livestock, as well as logging (the loss of old trees for nesting is a major problem that puts this species at a higher risk than the of the Maroon-fronted Parrot, When using the latter cliffs to build their nests).

    Confiscated and captive-bred birds were released in Arizona at the end of the Decade of 1960, with the first successful reproduction in EE.UU. shortly after, but unfortunately the birds have disappeared mostly from that area.

    There are no protected areas in Sierra Madre Occidental. The Appendix I. In danger.

    Conservation:

    • Red list category of the UICN current: In danger of extinction

    • Population trend: Decreasing

    The thick-billed Parrot is found in danger of extinction due to the destruction of nesting habitat, as well as its commercial exploitation, the decrease of population who have suffered these parrots is very evident to those that, long overdue, They inhabit the timber areas of Chihuahua and Durango (Lanning and Shiflett, 1981).

    The commercial logging of pine living for wood, as well as trees died standing for its pulp, they are ending with a lot of nesting sites effective and potential for these birds (Lanning and Shiflett, 1983).

    The trade of the parrots It seemed to be at least until the Decade of the eighties (Lanning and Shiflett, 1981), However, It is estimated that during 1985 and 1986 between several hundred and even thousands of parrots were illegally trafficked to the United States of America (Snyder & Wallace, 1988).

    To reduce these threats the species and its habitat, There are legal instruments such as the vedas and provisions in the Law-General ecological balance and environmental protection (LGEEPA) and the General wildlife law (LGVS); as well as the Norma Oficial Mexicana NOM-059-SEMARNAT-2001 It lists the species of wild flora and fauna Mexican under some category of risk and the mechanisms of inclusion and modification.

    The size of the population of the Thick-billed Parrot It is estimated between 2000-2800 mature individuals.

    In captivity:

    Its sale as a pet is illegal.
