I have a bird feeder that has a lot of traffic these days. Today, I took notice of two female cardinals. (Watch the video.) One hopped right up the feeder while the other sat on our deck railing. As I watched, one took food from the feeder and fed the one on the railing. As she fed it, the fledgling shook its wings in acceptance. I realized that she was teaching her young to find food on its own. This would relieve her of the endless duty of feeding her young. The young female could now feed herself and satisfy her hunger whenever she wanted.
