I remember one winter's day when I was a boy, watching with astonishment, a man standing in a park. He held out his hand with one sunflower seed at a time, and chickadees came to pluck them from his fingers. When I returned home, I tried it on our back porch with a bit of fruit cake. I saw a chickadee in a nearby bush, made a squeaking sound, and instantly was delighted to feel the delicate cool feet on my fingers and the little beak snatching my offering. - RB
