I vote for Magpies - they have such personalities. I have a nest (pile of twigs) in a Colorado Blue Spruce in my yard. The hatch from a couple of years ago seems to stay around. They love any of the seeds, but watching them try to get into a peanut is fun. They peck a hole and then carry it off to the field to eat. There are 8 of them and they come to the feeder only in the morning.
