I have 4- 6 crows that come to my backyard at least 3 or 4 times a week. They are a group who hang around together and its obvious that they're friends. they tend to feed on seeds that the songbirds throw down when they are feeding on my bird feeder. I love watching them fly and congregate together in the trees or on my front lawn looking for insects. I enjoy hearing the different calls they make. I wish I knew what their different calls mean. It looks like I live in an area (New Hampshire) where there are both crows and ravens but I've never seen a raven here.
