It may be crazy to hear... but this is a wild bird in Amsterdam! (I think you can consider it as fushion!) There is a a big population in some urban areas in the Netherlands and other parts of Europe. There's a big population living in the Vondelpark in Amsterdam, and the office where I'm doing my trainee is really close to the Vondelpark :-).
9/1/09: There is not only in Amsterdam a big population of this birds, but in many European city's and also North American city's. As long as there is food this birds will servive. Isn't that great! Well we don't have extreem cold winters in The Netherlands... but still I think this is unique :D
