Lord Derby's parakeet (Psittacula derbiana), also known as Derbyan parakeet, is a parrot species,[3] which is confined to a small pocket of moist evergreen forest in the hills and mountains of the Indian states of Arunachal Pradesh and Assam, and adjoining parts of Tibet, Sichuan and Yunnan in China.

[1] The species suffers from cutting of old trees (important for nesting sites) and poaching for the illegal wildlife trade.

[citation needed] Lord Derby's parakeets feed on fruits, berries, seeds, and leaf buds, occasionally foraging in gardens and fields.

[1] They have a mostly green plumage over their dorsal surface (i.e. from behind), black lores and lower cheeks, a bluish-purple crown and pale yellow eyes.

Juvenile birds have green crowns, orange-red upper and lower mandible (beak), and their irises are dark and do not lighten until they reach maturity between two and three years of age.
