1. Surprisingly, neighbor, crows eat very few nestlings, and squirrels, even chipmunks, are one of the biggest nest predators, along with snakes!
2. We see crows often in the rural area of Kentucky in which we live. There's usually a lookout/sentry and four to five more. I've never seen a crow's nest, but always look for nests when hiking.
3. Our area has American Crows but we are within 50 miles of raven habitat and have seen them there. While I am able to distinguish easily between their calls, I now know more of the physical characteristics that distinguish crows and ravens.
4. Crows alert other birds (and the neighborhood) to the presence of owls and hawks and they help keep the rodent population down.
