Habitat:
Observed in forest, between 1.250 and 4.000 meters above sea level. It is thought that you can make vertical migration seasonal. Views in the Tibet in 3.300 m, even in winter.
According to reports, have priority for coniferous forests or mixed forests of Pinus and Quercus, also of Alpine growth as the rhododendron. Visit valleys culture, especially during harvest.
Gregaria, usually seen in noisy flocks of up to several dozen birds. Only rarely are in pairs or individually.
Reproduction:
Holes for their nests they are located in tree hollows, usually at a certain height, commonly in a himalayan poplar Populus ciliata.
The breeding they performed it during the month of June.
The put in captivity is between 2 and 5 eggs.
Food:
Reported foods include barley, the corn, catkins of Populus ciliata, cones of Pinus tabulaefornis and fruit grown according to availability, including peaches; they can be highly destructive crops. It is believed that they may eat some invertebrates, Hoja-brotes and berries.
Distribution:
Distributed by the Of the Himalayas and South of the Tibetan plateau. Since Arunachal Pradesh and Assam, India, to the southeast of Tibet and Southwest China in Sichuan Western fence of 32 ยฐN and west of Yunnan to the South up to around Tengchong to 25 ยฐ N.
Visitors during the summer in the northeast of the India (May-September). Resident elsewhere, apparently with some seasonal altitudinal movements.
Usually common. Live birds traded in small numbers with a modest population captive outside their area of distribution.
Conservation:

Near Threatened โ (UICN)โ

โข Current Red List of UICN: Near-threatened
โข Population trend: Decreasing
The population of the Derbyan Parakeet It is suspected that it may be suffering a moderately rapid decline mainly due to the pressure that is subjected , not only due to its continuous capture for the cage bird trade, but also by the indiscriminate felling of trees in the nest, together with evidence of local extinctions and declining birds in some parts of its area of distribution.
Threats:
-
– This species was previously threatened by deforestation campaigns, that it resulted in, loss of much of their breeding habitat; However, This threat ended in the Decade of 1990 (Zeidler and Francis 2011).
– Today, Middle-aged trees, some of which provide the perfect place for the construction of the nest, they are being felled for the construction of housing and firewood, even in protected forests (Zeidler and Francis 2011).
– Recent observations indicate that this species is subject to a strong pressure catch and the collection of eggs for the pet trade (J. Eaton in litt. 2010, Zeidler and Francis 2011).
– The collection of eggs and subsequent incubation, for the breeding of Derby Parrots and subsequent sale, is very organized in some areas (Zeidler and Francis 2011).
– The species is sold openly and are kept, in large numbers, as a pet in its natural distribution area (J. Eaton in litt. 2010, J. Hornskov in litt. 2010, Zeidler and Francis 2011).
Actions of conservation in CITES Appendix II course.:
-
– Is listed in Schedule I of the law of 1972 for nature (Protection) on India (The India Government, 1993) and the collection for the pet trade is illegal in China (Zeidler and Francis 2011).
– In some areas, as the Shachong valley (Szechwan), the monks provide protection for wildlife, including trap activities (Zeidler and Francis 2011).
Conservation Actions Proposed:
-
– Population trends and monitor hunting pressure.
– Addressing the threat of trade through the application of the legislation and awareness-raising activities.
– Steadily increase the number of sites that are protected.
– Support monks engaged in activities for the protection of wildlife (Zeidler and Francis 2011).
– Evaluate the effectiveness of a scheme of nest boxes (Zeidler and Francis 2011).
"Derbyan Parakeet" in captivity:
The Derbyan Parakeet is a pet very popular at the local level due to the wonderful color of its plumage, his intelligence and its excellent speaking skills, that distinguishes it from other Asian parrots, usually you do not have that voice clarity.

The Derby Parrot reach sexual maturity between the 2 and 3 years of age. It reported that it may reach sexual maturity later in nature, possibly to the 5 years.

It requires much interaction to keep its meekness. By nature, it is a shy bird to human contact, Although considered usually placid compared to some other parrots.
If they are kept outdoors they may require periodic deworming – since they spend considerable time at the bottom of your aviaries or cages. Because of this habit, they are also susceptible to fungal infections. Good hygiene is especially important to keep healthy this Parrot.
Even so, the Derby Parakeet is a rare bird outside its range and with limited breeding.
