From my experience the best Crow hunting is out in the country where you can set up where crows are roosting at night. About an hour before sundown hide in some brush and wait for the sun to start going down. The crows will start flying in. they can't see you because the ground looks black under them. At first when you shoot the other crows will fly away. But as the sun goes down they become desperate to land for the night and we'll keep flying in even while you shoot.
