I feed crows mornings in my back yard. If I’m late they gather on the roof and call until I come out with peanuts and kibbles. One crow sits on top of the bird feeder post and observes. Since I started this coarse I found a nest in a tall river birch in our yard. At first they would only come for food if I went inside but now they come if I’m sitting or walking around. I talk to them when I put the food out so they become familiar with my voice. Yesterday they drove off two hawks. If I put out stale bread they take it to the nearby pond and soften it up
I have seen them in the western states. On the Madison River I watched them raise 3 Babies over the summer. I was fishing from a boat and their nest, mostly a pile of sticks, was in an indentation on a cliff face
1 Statiscally, snakes and squirrels are the prime predators for song bird nestlings
2 I feed American crows in my backyard in southeastern NC I will look for nests on my walks in the future
3I don’t believe there are any ravens here and I have never seen one
4/crows warn of predators. I have seen the crows in my backyard chase hawks away.
