[Illustration: Mountain Quail.] A mocking-bird or a robin will let her train just touch the ground when she stretches up to look about her; but when she begins to walk again she lifts it. So you never see the tip of the longest tail one bit draggled, unless the bird is wounded or sick. If you watch closely, you will learn to tell a male bird from a female bird by its dress. To be sure, his coat skirts are cut so much like the dress of his mate that we sometimes have to imagine a good deal to see any difference. But, as a rule, you can tell the male or gentleman bird because he dresses so much more gayly than his mate, although we do not think he spends quite so much time as she in fixing and mending his clothes and in bathing. The lady bird works harder than her mate in going to market to get lumber and nails for her house or cradle, and so she soils her clothes more. Then she sits longer in the nest and works harder in many ways, never once thinking about putting on an apron. You must not think too hard of the gentleman birds for letting their mates do the most of the home work, for you remember that it is the male who must always be ready for his place in the orchestra at a moment's notice. He is obliged to make most of the music, and if he should neglect his duty he would probably lose his place and be put out of the choir. A singer bird has no notes spread out before him, but must go over and over his part, until he knows it by heart with no one to prompt him. You need not be surprised because we said a bird must get lumber and nails for her house or cradle. If she did not have lumber and nails, she could not do her work. Of course you never hear her pounding with a hammer, still she uses what may be called nails, as you shall see by and by. I should not have to change my dress Were I a bird in yonder tree, And say, "Excuse me, if you please," When callers come to visit me. But I would fly upon a bough. And say, "My dear, come right up here." And we would sit and swing and chat Beneath the sky so blue and clear. [Illustration] CHAPTER VI. WHAT BIRDS CARRY IN THEIR POCKETS. Some birds wear on their heads plumes, or bright and showy hats. These they sometimes lift in true bird style. There is the ruby-crowned kinglet[4] which one sees in the garden trees. When this little king lifts his hat, he shows what looks like a ruby crown or jewel on top of his head. [4] _Regulus calendula._ Other birds wear cocked hats, or tall silk hats with waving plumes. You can imagine almost anything you like in the dress of a bird, from his hat to his shoes. When a bird who wears a hat is surprised by another bird, or is angry, or when he wants to "show off" to his mate while paying his respects to her, he lifts the feathers on the top of his head; and this is what we call "lifting his hat."
