If a neighbor complained about crows eating baby birds, I would agree, but tell them that squirrels, chipmunks, snakes, and raccoons eat a lot more baby birds than crows do, citing the information from tis course.
I remember hearing crows early in the morning year round when growing up in the Chicago suburbs. It was a sound I loved waking up to as a child, and have continued to treasure as an adult in New England. In Boston, I see crows in parks. In rural Maine, they are often along roadsides or in the woods.
There are ravens and crows in Maine. I've spotted a raven a time or two but see crows often. I've also heard what I thought was the croak of a raven deep in the woods, but as I learn more about the crow's vocal repertoire, I'm not so sure.
Any bird or rodent small enough to make a good meal for a hawk or eagle benefits from having a flock of crows in the neighborhood because the crows often mob large raptors.
