I had posted a photo a couple of weeks ago of a Tufted Titmouse with a peanut in it's beak. This photo shows that they actually do eat them. I had originally bought the peanuts with the thought of feeding blue-jays but so far it's these Titmice that are getting the most of them. It's cute to watch them breaking the shell open to get at the peanut. It's fun to watch them come get them too. The peanut is so big in comparison, a lot of the time they drop them as they try to fly off with it and then have to go pick it up again.
