Pyrrhura hoffmanni gaudens
(Bangs, 1906) – Very similar to nominal, although feathers crown and the nape They have yellower, with their ends red or red and orange (in some birds, red ends of the feathers may extend over the back, the throat and the breast). Underparts slightly darker.
Pyrrhura hoffmanni hoffmanni
(Cabanis, 1861) – Nominal.
Observed, mainly, in mountainous areas, preferring montane forests in the subtropical zone, mainly 1.000 to 2.400 meters above sea level, although views 550 meters in the region Almirante Bay, Panama and a 3.000 metres in Costa Rica.
They appear to tolerate a considerable disturbance of habitat, including managed forests, areas and the second growth partially cleared, forests and wooded pasture shrubs. Usually seen in pairs or small flocks of 5-15 birds. You can perform altitudinal movements daily to feed, returning to the mountains to rest. Forage occurs in the canopy or smaller trees and bushes near the edge of the woods.
They nest in tree hollows, including old nests woodpeckers, to 8-20 meters of land. With reproduce dry season (January June). Clutch six eggs in captivity.
ExtensiÃ³n de su Ã¡rea de distribuciÃ³n (reproductores / residentes): 18.400 km2
Confined south of Costa Rica and western Panama.
The species is found in the highlands of the southern half of Costa Rica, including the slopes of Caribbean, the mountains of the central plateau south and the two sides of the Cordillera de Talamanca, sometimes the region Cartago and Paradise and the Irazu volcano.
In western Panama They are mainly distributed in the west and center ChiriquÃ and areas adjacent in Bull's mouths, in the highest mountains (including the Chiriqui volcano and the high ridges on Boquette) and at lower elevations around, for example, of the Chiriqui Lagoon and Admiral Bay.
The easternmost Panamanian registry was found east of the central mountain range in 1868.
Some altitudinal movements (higher in the dry season). Birds are perhaps only sporadic in the extremities of their range. Apparently, It is common in middle to high elevations Cordillera de Talamanca and in isolated areas, and it is believed to be quite numerous throughout the main range.
Its Habitat It is now highly fragmented, though still apparently numerous, even in areas where the forest is partly cloudy. Rare in captivity.

Pyrrhura hoffmanni hoffmanni
(Cabanis, 1861) – Nominal. South of Costa Rica.
Justification of the red list category
Although this species may have a small range, it is not believed that approximates the thresholds for Vulnerable under the criteria of size range (Extension <20,000 km2 combinada con un tamaÃ±o de rango decreciente o fluctuante, extensiÃ³n / calidad del hÃ¡bitat o tamaÃ±o de la poblaciÃ³n y un pequeÃ±o nÃºmero de lugares o fragmentaciÃ³n severa). La trend of the population It appears to be stable, so that the species does not approach the thresholds for Vulnerable under the criteria of population trend (> 30% decline over ten years or three generations). The population size It has not been quantified, but it is not believed to be close to the thresholds for Vulnerable under the criterion of population size (<10.000 individuos maduros con un declive continuo estimado> 10% in ten years or three generations or a population structure). For these reasons, the species is evaluated as Least Concern.
Justification of the population
The size of the world's population has not been quantified, but this species is described as “quite common” (Stotz et to the., 1996).
Justification of trend
They suspected that the population of Catana Cotorra is stable in absence of evidence of any decline or threatens substantial.
Rare in captivity. Quieter than other parakeets. In Panama the export of these birds is prohibited from 1980.
