If you watch long enough, after a while you may see the old bird, who is training a young one, fly away. She may leave the young one alone on a tree or the ground, and be gone a long time. Before many minutes the little one will get hungry, and begin to call for food. But by and by, if nobody comes to feed him, he will think to look around for something to eat. Thus he will get his lesson in helping himself. Once I saw a woodpecker father bring his little one to a fence, close by some raspberry bushes that were full of berries. He fed him two or three berries, to teach him what they were and where they grew, and then quietly slipped away. When the young bird began to feel hungry he cried out; but nobody came. Then he looked over at the raspberries, and reached out and tried to get hold of one. After trying three or four times, and nearly pitching off his perch, he did reach one. Then how proud he was! The father stayed away an hour or more, and before he came back that young woodpecker had learned to help himself very well; though the minute his father came, he began to flutter his wings and beg to be fed, as if he were half starved. A lady, who fed the wild birds on her window sill for many years, and watched their ways, says she often saw the old birds teaching their little ones. They showed them where the food was to be found, and, she says, regularly taught them the art of eating. Then she saw them taught to be afraid of people, not to come too near her. And once she saw an old bird showing a young one how to gather twigs for nest-building. The young one looked on a while, and then tried hard to do it himself, but could not get off a single twig. Best of all, the same lady heard an old robin giving a music lesson. The teacher would sing a few notes and then stop, while the pupil tried to copy them. He had a weak, babyish sort of voice, and did not succeed very well at first. I have heard several birds at their music lessons. X SOME OF HIS LESSONS IT is very easy to catch the birds teaching their little ones to exercise their wings and to fly together. You will see the young birds sitting quietly on fences or trees, when all at once the parents begin to fly around, with strange loud calls. In a minute every youngster will fly out and join them. Around and around they all go, hard as they can, till their little wings are tired, and then they come down and alight again. Once I saw a young bird who did not go when his parents called. All the others flew around many times, and I suppose that young one thought he would not be noticed. But mothers' eyes are sharp, and his mother saw him. So when she came back, she flew right at her naughty son, and knocked him off his perch. The next time she called, he flew with the rest. This was a crow mother.
