Somebody should have told the squirrels.
Actually, someone did. My cousin's four year-old daughter loudly admonished the squirrel that the food was NOT. FOR. SQUIRRELS! knocking furiously on the window as she did so. As funny as that was, nothing prepared me for when she turned around and announced that she needed to call Grandma and tell her that feeder did not work like it was supposed to and the squirrels were eating the bird food. (She's four!!!)
I can't help but be a little impressed my his acrobatics, though.
