Scarcely is it finished before the skulking cowbird watches her chance to lay an egg in it that she may not be bothered with the care of her own baby. She knows that the yellow warbler is a gentle, amiable, devoted mother, who will probably work herself to death, if necessary, rather than let the big baby cowbird starve. But she sometimes makes a great mistake in her individual. Not all yellow warblers will permit the outrage. They prefer to weave a new bottom to their nest, over the cowbird's egg, although they may seal up their own speckled treasures with it. Suppose the wicked cowbird comes back and lays still another egg in the two-storied nest: what then? The little Spartan yellow bird has been known to weave still another layer of covering rather than hatch out an unwelcome, greedy interloper to crowd and starve her own precious babies. Two and even three-storied nests are to be found by bright-eyed boys and girls.🏁
