Last year, I fed a chipmunk till hibernation time. I somehow think this chippy must be the same one as last year. She came out of her hole in early spring, ran up to me and stood on her two back legs wanting food. I've tried feeding a few other chipmunks and they're not nearly as friendly as this little chippy. Now that I've bought peanuts, there's no stopping her. Yesterday, she jumped on my lap wanting more.
