Alex Joseph, a West Indian-born parks worker, rakes the lawn at the grandly gothic Greenwood Cemetery in Brooklyn when he and his fellow laborers hear what sounds like a flock of sea gulls dive-bombing at their heads. The workers instinctively duck and whip round and look up and see — those crazy green parrots, expertly mimicking the sea gull’s caw.“Man, they do that a couple times a week just to play with our minds,” Joseph said, grinning wide and shaking his head. “They are a crazy bunch of immigrants, those birds.”
They are the wild parrots of Brooklyn, these emerald-feathered yakkers with the wisenheimer sense of humor.

Here’s an entire website dedicated to feral monk parakeets in North America. If you spot one, let these guys know.

:) Parrots are amazing creatures indeed. They are very inteligent. Does “new” free parrots that are over our backyards, our parks, are a new generation of “free thinkers”.
