The Rose-ringed Parakeet, Psittacula krameri, also known as the Ring-necked Parakeet, is an elegant medium-sized member of the parrot family Psittacidae. A popular pet at various times, dating back to the ancient Greeks and Romans, escaped individuals have colonised various cities throughout the world, adapting well to their surroundings.

Adult males have a pink and black neck ring, and the female and immature birds of both sexes either have no neck rings or just a pale to dark grey ring. Both sexes have a distinctive green colour in the wild with a red beak and long blue tail. Captive bred birds have multiple colour mutations, as one might expect, including white, blue and yellow. Rose-ringed parakeets measure up to 40 cm (16 in) in length.

Diet consists manly of seeds, nuts, fruits, and berries and these birds will visit garden bird feeders when hungry. Although popular as pets, they are not liked by farmers as they tend to cause a fair amount of damage to crops. There could be up to around 100,000 feral birds in Europe
