I hate to be contrary, BUT this is not odd behavior at all. Crows have been congregating in large "roosts" in the fall and winter as long as there have been crows. I live in a northern Canadian town and am able to watch bird and animal behavior most of the time. This doesn't mean that the OP is wrong in her observation, though. Something has been changing, but it's not the behavior of the birds....it's the location of the roosts and the fact that more people are observing them.
