Mr. Goldfinch was sure that they had built too near the ground, and he had chosen a crotch above. Toward this he was dragging the bits of grape-vine and cedar-bark which were woven into their first nest. He said they could also use some of the grasses and mosses which they had gotten together, and he even told his wife of some fine thistle-down which he could bring for the inside, where the eggs were to be laid. Mrs. Goldfinch watched him tugging with bill and both feet to loosen the bits of bark, and she said to herself: "Dear fellow! what a helper he is! I won't mind rebuilding if it makes him happy," and she went to work with a will. When the sun went down in the west the next night the second nest was done, and it was the last thing at which the Goldfinches looked before tucking their heads under their wings and going to sleep. It was the first thing that they saw the next morning, too, and they hopped all around it and twittered with pride, and gave it little tweaks here and little pokes there before they flew away to get breakfast. While they were gone, Mrs. Cowbird came walking over the grass and dry leaves to the foot of the tree. She wagged her head at every step, and put on as many airs as though she were showily dressed, instead of wearing, as she always does, a robe of dull brownish gray. She had seen the Goldfinches fly away, and she was looking for their home. She was a lazy creature in spite of her stirring ways, and she wished to find a nice little nest in which to lay an egg. You know Cowbirds never think of building nests. They want all of their time to take care of themselves, which is a very foolish way of living; but then, you could never make a Cowbird think so! "That nest is exactly right," said Mrs. Cowbird. "I will lay my egg there at once, and when Mrs. Goldfinch has laid hers she will have to hatch them all together and take care of my baby for me. What an easy way this is to bring up one's family! It is really no work at all! And I am sure that my children will get along well, because I am always careful to choose the nests of small birds for them. Then they are larger and stronger than the other babies, and can get more than their share of food." So she laid a big white egg with gray and brown spots on it in the Goldfinches' new home, and then she flew off to the Cowbird flock, as gay and careless as you please. When the Goldfinches came back, they saw the egg in their nest and called all their neighbors to talk it over. "What shall I ever do?" said Mrs. Goldfinch. "I wanted my nest for my own eggs, and I meant to lay them to-morrow. I suppose I shall have to sit on this one too, but it won't be at all comfortable." "I wouldn't," said one of her neighbors, a Yellow Warbler. "I left my nest once when such a thing happened to me, and built a new one for my own eggs." "Oh dear!" cried Mrs. Goldfinch, "we have built two already, and I cannot build another."
