The shedding of the feathers brings many risks to the birds; but Nature leaves none of her children utterly helpless. The geese at this time cannot fly because their feathers are gone; but they can swim, and so get away from most of their natural enemies. On the other hand, the hawks that hunt by wing, and must have wings always in good feather, or else perish, lose their feathers so slowly that they never feel their loss. It takes a hawk nearly a year to get a complete change of wing feathers, one or two dropping out from each wing at a time, at long intervals apart. Then here is the gosling, that goes six weeks in down, before it gets its first feathers, which it sheds within a few weeks, in the fall. Whereas the young quail is born with quills so far grown that it is able to fly almost as soon as it is hatched. These are real mature feathers; but the bird is young and soon outgrows these first flight feathers, so they are quickly lost and new ones come. This goes on till fall, _several_ moults occurring the first summer to meet the increasing weight of the little quail’s growing body. I said that Nature was severe and methodical, and so she is, where she needs to be, so severe that you are glad, perhaps, that you are not a crow. But Nature, like every wise mother, is severe only where she needs to be. A crow’s wing feathers are vastly important to him. Let him then take care of them, for they are the best feathers made and are put in to stay a year. But a crow’s tail feathers are not so vastly important to him; he could get on, if, like the rabbit in the old song, he had no tail at all. In most birds the tail is a kind of balance or steering-gear, and not of equal importance with the wings. Nature, consequently, seems to have attached less importance to the feathers of the tail. They are not so firmly set, nor are they of the same quality or kind; for, unlike the wing feathers, if a tail feather is lost through accident, it is made good, no matter when. How do you explain that? Do you think I believe that old story of the birds roosting with their tails out, so that, because of generations of lost tails, those feathers now grow expecting to be plucked by some enemy, and therefore have only a temporary hold? The normal, natural way, of course, is to replace a lost feather with a new one as soon as possible. But, in order to give extra strength to the wing feathers, Nature has found it necessary to check their frequent change; and so complete is the check that the annual moult is required to replace a single one. The Japanese have discovered the secret of this check, and are able by it to keep certain feathers in the tails of their cocks growing until they reach the enormous length of ten to twelve feet.
