We are told that these critters are from the amazon forest and that they can't survive the harsh winter here. And yet, if you ask anyone who works in construction, he'll tell you all about entire parakeet villages under bridges, on top of cell phone towers, etc.
I'm an engineer. We've been preparing for a major project in the Midwest. You know what us engineers do while we have nothing to do? We stand around and stare at the parakeet villages (nests) and wonder how the hell they survive the winter here. We know they don't migrate south. What the hell do they eat in December, January, and February?
What's more, I've been observing over the years that every year there are more and more of them. They don't bother anyone, so most people don't even notice. But they are everywhere.
A couple years ago, I was working on a bridge in Chicago. And there they were under the bridge. Whole village of them. There must have been hundreds or even thousands. We tried to leave them alone. None of us wanted to bother them. And all that time we were working on it, we kept wondering how the hell they survive the harsh winter here.
If you do a search on the internet, you're not going to find anything. Shouldn't this be on the discovery channel or something?
