One of my favorite things about having a bird feeder in my last apartment was watching the male cardinal, from the pair that frequented my feeder for a few years, feed the female. The feeder was situated above a sunken window that had a brick border around it. The male would fly to the feeder, grab a seed and then fly down to the brick wall and drop it in his mate's open beak. It was touching. I found a picture of the act on Yahoo! news tonight.
