“I suppose,” said Peter, looking at Teacher thoughtfully, “they've given you that name because you are dressed something like the Thrushes. That olive-green coat, and white waistcoat all streaked and spotted with black, certainly does remind me of the Thrush family. If you were not so much smaller than any of the Thrushes I should almost think you were one myself. Why, you are not very much bigger than Chippy the Chipping Sparrow, only you've got longer legs. I suppose that's because you spend so much time on the ground. I think that just Teacher is the best name for you. No one who has once heard you could ever mistake you for any one else. By the way, Teacher, where did you say your nest is?” “I didn't say,” retorted Teacher. “What's more, I'm not going to say.” “Won't you at least tell me if it is in a tree?” begged Peter. Teacher's eyes twinkled. “I guess it won't do any harm to tell you that much,” said he. “No, it isn't in a tree. It is on the ground and, if I do say it, it is as well hidden a nest as anybody can build. Oh, Peter, watch your step! Watch your step!” Teacher fairly shrieked this warning. Peter, who had just started to hop off to his right, stopped short in sheer astonishment. Just in front of him was a tiny mound of dead leaves, and a few feet beyond Mrs. Teacher was fluttering about on the ground as if badly hurt. Peter simply didn't know what to make of it. Once more he made a movement as if to hop. Teacher flew right down in front of him. “You'll step on my nest!” he cried. Peter stared, for he didn't see any nest. He said as much. “It's under that little mound of leaves right in front of your feet!” cried Teacher. “I wasn't going to tell you, but I just had to or you certainly would have stepped on it.” Very carefully Peter walked around the little bunch of leaves and peered under them from the other side. There, sure enough, was a nest beneath them, and in it four speckled eggs. “I won't tell a soul, Teacher. I promise you I won't tell a soul,” declared Peter very earnestly. “I understand now why you are called Oven Bird, but I still like the name Teacher best.” Feeling that Mr. and Mrs. Teacher would feel easier in their minds if he left them, Peter said good-by and started on for the lonesome place in the Green Forest where he knew the old nest of Redtail the Hawk had been. As he drew near the place he kept sharp watch through the treetops for a glimpse of Redtail. Presently he saw him high in the blue sky, sailing lazily in big circles. Then Peter became very, very cautious. He tiptoed forward, keeping under cover as much as possible. At last, peeping out from beneath a little hemlock-tree, he could see Redtail's old nest. He saw right away that it was bigger than it had been when he saw it last. Suddenly there was a chorus of hungry cries and Peter saw Mrs. Redtail approaching with a Mouse in her claws. From where he sat he could see four funny heads stretched above the edge of the nest.
