What I notice is that I almost never see crows anymore. I'm thinking that West Nile has taken them out. They used to hang out on power lines in numbers like you'd expect to see pigeons.
I think they all moved to Texas. Often, in the evening, they cover almost every tree, power line, roof top, sign, and parking lot in some areas (and poop on the rest). If you miss them, we'll be happy to give you all can catch or shoot and carry.
We don't have many bald eagles around, but lots of hawks, owls and other attack birds.
