The Ring-necked or Rose-ringed Parakeet (Psittacula krameri) is a mainly green parrot with a red bill and a long, tapered tail. This is the most widely distributed parrot, occurring in northern Africa as well as across much of southern Asia. In southern Asia, it is found from western Pakistan and southern Nepal through India, Sri Lanka, and Bangladesh to southern Burma. It is frequent to abundant in Africa and most of Asia (fairly common in Burma). Abundance has increased during the 20th century with expanding agriculture and the species is widely bred in captivity. It is distinguished from all other Psittacula species by the combination of a green or bluish-green head, pale green body, absence of maroon shoulder patches, and (in adult males) black and pink collar markings. Ring-necked Parakeets are very noisy, especially at communal roosts.

Rose ringed parakeet (Scopoli, 1769) is sexually dimorphic bird. The adult male sports a red or black neck-ring and the hen and immature birds of both sexes either show no neck rings, or display shadow-like pale to dark grey neck rings. Indian rose-ringed parakeets measure on average 40 cm (16 in) in length including the tail feathers, a large portion of their total length. Their average single wing length is about 15-17.5 cm (5.9-6.9 in).

In the wild, rose-ringed parakeets usually feed on buds, fruits, vegetables, nuts, berries and seeds. Feeding on winter pea crops provides the female with nutrients necessary for egg production. One of the few parrot species that have successfully adapted to living in "disturbed habitats".

In north-west India, Indian rose-ringed parakeets form pairs from September to December. They do not have life mates and often breed with another partner during the following breeding season. From April to June, they care for their young. Fledglings are ready to leave the nest before monsoon.

Both males and females have the ability to mimic human speech. First the bird listens to its surroundings, and then it copies the voice of the human speaker. Some people hand-raise rose-ringed parakeet chicks for this purpose. Such parrots then become quite tame and receptive to learning.
