It was only for an instant that Zee Zee sat still; then he was in the air, darting, diving, whirling, going through all sorts of antics as he caught tiny insects too small for Peter to see. Peter began to wonder how he kept still long enough to sleep at night. And his voice was quite as busy as his wings. “Zee, zee, zee, zee!” he would cry. But this was only one of many notes. At times he would sing a beautiful little song and then again it would seem as if he were trying to imitate other members of the Warbler family. “I do hope Zee Zee is going to stay here,” said Peter. “I just love to watch him.” “He'll stay fast enough,” retorted Jenny Wren. “I don't imagine he'll stay in the Old Orchard and I hope he won't, because if he does it will make it just that much harder for me to catch enough to feed my big family. Probably he and Mrs. Redstart will make their home on the edge of the Green Forest. They like it better over there, for which I am thankful. There's Mrs Redstart now. Just notice that where Zee Zee is bright orange-y red she is yellow, and instead of a black head she has a gray head and her back is olive-green with a grayish tinge. She isn't nearly as handsome as Zee Zee, but then, that's not to be expected. She lets Zee Zee do the singing and the showing off and she does the work. I expect she'll build that nest with almost no help at all from him. But Zee Zee is a good father, I'll say that much for him. He'll do his share in feeding their babies.” Just then Peter caught sight of a bird all in yellow. He was about the same size as Zee Zee and was flitting about among the bushes along the old stone wall. “There's Sunshine!” cried Peter, and without being polite enough to even bid Jenny Wren farewell, he scampered over to where he could see the one he called Sunshine flitting about from bush to bush. “Oh, Sunshine!” he cried, as he came within speaking distance, “I'm ever and ever so glad to see you back. I do hope you and Mrs. Sunshine are going to make your home somewhere near here where I can see you every day.” “Hello, Peter! I am just as glad to see you as you are to see me,” cried Sunshine the Yellow Warbler. “Yes, indeed, we certainly intend to stay here if we can find just the right place for our nest. It is lovely to be back here again. We've journeyed so far that we don't want to go a bit farther if we can help it. Have you seen Sally Sly the Cowbird around here this spring?” Peter nodded. “Yes,” said he, “I have.” “I'm sorry to hear it,” declared Sunshine. “She made us a lot of trouble last year. But we fooled her.” “How did you fool her?” asked Peter. Sunshine paused to pick a tiny worm from a leaf. “Well,” said he, “she found our nest just after we had finished it and before Mrs. Sunshine had had a chance to lay an egg. Of course you know what she did.” “I can guess,” replied Peter. “She laid one of her own eggs in your nest.”
