The rose-ringed parakeet, also known as the ring-necked parakeet, is a gregarious tropical Afro-Asian parakeet species that has an extremely large range. Indian rose-ringed parakeet (Psittacula krameri manillensis) is a subspecies that originates from the southern Indian subcontinent. 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. Both sexes have a distinctive green colour. Rose-ringed parakeets measure on average 40 cm (16 in) in length, including the tail feathers, a large portion of their total length.
