a toddler's approach to squirrels

LittleBirder went outside today with a bird book, notebook, and crayon. Came in to tell me of a "chipmunk" eating seed in the green feeder that is (in his mind) for chickadees. We talked about how he could scare away a red squirrel by going out and talking to it. In the back of my mind is the idea the squirrel might become habituated to him and he could eventually feed it. I wonder how likely that is? And I wonder if the uneven bit of fur on a red squirrel (the same one? A different one?) is a scar (thus earning it the name "Nibbles") or just a rain-soaked and temporary look.

I wonder where Stubbs is, and how -- whether he survived the summer.
