Again, similar experience. When I was a kid I also tried to hunt crows and I never got close enough to even try. I enjoy crows and I enjoy hearing their different vocabulary, especially when they are in a family setting.
I have observed the same behavior in Mississippi and Georgia so it seems to be fairly common. I throw out crust from sourdough bread I bake and they almost always soak it. They also wash McDonalds food wrappers.
