Well, yesterday after I had come back from a bike ride at a nearby forest preserve, I found a flying squirrel on our feeder. I sauntered right up and petted him, and he didn't care. First his tail, then his back. I think I spooked him after a couple of seconds because he bolted right up the tree. And then he flew into our neighbor's yard. That must have been the fourth or fifth time that I've seen him.
