Sometimes, with the best of intentions, people try to establish a bird species in a new place. Sometimes it works; that's called Introduction. Sometimes it doesn’t; that's called failure. But sometimes it works really, really well, and that's called a mess. That's what we have with these guys. True they were invited (introduced), but that didn't give them a license to make a nuisance of themselves. They've invaded. There are millions of them here. They aren't good for much and elbow out better looking birds, so we birders tend not to like them very much. Some of us get downright grumpy about it. There are states that have even tried to kill them. All of them. It didn't work.
I think we're stuck with them don't you? It's all Shakespeare's fault you know.
But more on that tomorrow. :)
