Rose Ringed Parakeet
Scientific name : Psittacula krameri
These are vibrantly bright green parakeet, frequently found in woodland, parks, and gardens, feed mainly in trees. Nests in cavities, including holes in buildings. Easily overlooked if quiet, as the bright green plumage blends easily with foliage. Note the very long slender tail, bright red bill; male has narrow black-and-rose neck ring. Closely resembles the larger Alexandrine Parakeet, which has a wine-red patch on each shoulder. Like other parakeets, raucous and social, often appearing in noisy groups. Native to Africa and South Asia, introduced locally in Europe and Japan.
