Some birds have two, different colored dresses in a year; one they get without changing a feather. Suppose they have feathers of black, with gray on the outside edges. All winter the gray shows and the birds seem to have gray coats. But in spring the gray edges wear or fall off, and the black shows, and then they look as if they had come out in new black suits. It is as if you should take off a gray overcoat and show a black coat under it. There is another interesting thing about birds' dress. Some of them look like their mates, the father and mother birds so nearly alike that it is hard, sometimes impossible, to tell them apart. But when that is the case, you will notice that the color is not very gay. If the father wears a bright-colored suit, the mother does not look like him. For this reason the little mother is not too easily seen when she is on her nest. If the goldfinch mother were as bright as her mate, everybody who came near would see her on the nest, and some animal might take her, and leave the young birds to starve to death. That is probably why mother birds dress in such dull colors. When birds live on the ground, or very near it, in most cases both of the pair wear the dull colors, so they will not easily be seen. Wrens and sparrows and many others are so. But birds who make their nests in holes, or under ground, are often as bright as their mates, because they cannot be seen while sitting, and do not need to wear dull colors. A curious thing about a bird's color is that the same species, or kind of bird, is darker in one place than another. Where there is much dampness or wet weather, the colors are darker. For instance, a bob-white who lives in Florida, or one who lives in Oregon, will be much darker than his cousin living in New England. VIII HIS FIRST FLIGHT WHEN young birds are in the nest they are not very pretty. But when they are nearly feathered, and sit up on the edge, exercising their wings, and getting ready to fly, they are lovely to look at. Their feathers are more fluffy and fresh than those of the old birds. At that time they have not learned to be afraid of us, and if we do not frighten them by roughness, loud talking, or quick movements, we can often get near enough to see them well. They will sit up and look at us without fear. Then some day, all at once, a young bird will begin to flap his wings, and off he will go, fluttering very hard, beating his wings, and trying to reach the next tree. Sometimes he will reach it, and perch on a twig, and sit quite still a long time, tired with his first flight. Then the parents will come and feed him, and after a while he will fly again. This time he will go farther. So he will go on, till in a few days he can fly very well, and follow his parents about, and begin to learn where to get food.
