THE SWALLOWS _Five Swallows and a Changeling_ “I wonder if there is a child living in the real country who does not know a Swallow by sight the moment its eyes rest upon the bird? I think not, and a great many people who are only in the country at midsummer and in early autumn also know the Swallows, even though they cannot tell the different kinds apart, for during the nesting time, as well as the flocking period that follows, Swallows are conspicuous birds of the air and leaders of the birds that might be grouped as “The Fleetwings.” For not only do Swallows get their food while on the wing, now pursuing it through the upper air if the day is fair, now sweeping low over meadow, pond, and river if the clouds hang heavy and insect life keeps near to the ground, but during the flocking season, when the separate families join in the community life that they live through the winter, the Swallows are constantly on the wing. “The day that we had the orchard party you all noticed the Swallows flying over the pond between the orchard and river woods, sometimes alighting so close together on the bushes as to be as thick as the leaves, and then again stringing along the telegraph wires, above the highway, some heading one way and some another until, evidently at a signal, they flew off again and disappeared in the distance, until they seemed but a cloud of smoke. “We agreed, I think, some time ago, that it is much better to learn the real names of people, animals, and flowers than to simply give general names. It is more definite to say, “I saw a Swallow” flying over the moor or meadow, than to say, “I saw a bird” flying over the meadow; but it would be more interesting still if we tell the name of the particular kind of Swallow that was seen, for among the many kinds that exist at least five are quite common, according to the part of the United States in which one lives. “Can any of you tell me the names of these Swallows, how they differ in plumage, and where they live? I can see by Dave’s face that he knows something about them and I think Sarah Barnes does also, while as for Tommy Todd, both hands are up in spite of jack-knife and the windmill he is making and he can hardly wait for me to stop. “Now, Tommy, how many kinds of Swallows do you know?” “Three!” he replied promptly. “Barn Swallows, and Chimney Swallows, and Dirt Swallows!” “I have heard of Barn and Chimney Swallows, but never of a Dirt Swallow. Please describe it to me,” said Gray Lady, looking interested. Tommy hesitated for a minute, for it is one thing to know a bird by sight, but quite another to carry a correct picture of it in your mind’s eye and then put it into words.
