Los Angeles, my home, is host to thousands of wild parrots. And their numbers are increasing. Almost daily I see flocks of amazons and conures fly past overhead. Military macaws roost in eucalyptus trees and on deck railings. Where are these birds coming from? Not all, or probably even most, are escapees. These flocks are established and reproducing. Of course, their numbers are added to by escaped birds, and by birds that have so annoyed their owners that they have been set free. Brooklyn, San Francisco, London, and even the Netherlands have established flocks too. Few things are more incongruous than walking down a cobbled lane in Amsterdam and seeing a macaw dart past.

Unlike most introduced species, wild parrots don't seem to be causing too much environmental havoc. This is partly because they haven't yet crossed over into the wild lands that ring most cities, and partly because they live almost exclusively off of non-native plants. In other words, the environmental harm has already been done. The parrots are merely the beneficiaries.
Are we going to someday see huge flocks, hundreds of birds strong, wheeling over our cities? I don't know, but it's a remote possibility. After all, prior 1904 when the last native North American parrot was killed in Florida, huge flocks of Carolina parakeets were a common sight in the Eastern U.S. So grab a Mai Tai and keep an eye on that bird feeder!
