These parakeets where unfortunately introduced all over the World as pets, some stupid people let them in the wild, now we can see them everywhere, from Barcelona, to Tokyo! A tremendous stupidity!
I think the same parakeets live in the free in Heidelberg, Germany. They have the same colour and have the black band around the neck. But it is another climate, not the Indian heat. Seehttp://www.pbase.com/ragnarandren/image/166308205
