“As sure as I live,” thought Peter, “that was Mrs. Blacky, and Blacky brought her some food so that she would not have to leave those eggs she must have up there. He may be the black-hearted robber every one says he is, but he certainly is a good husband. He's a better husband than some others I know, of whom nothing but good is said. It just goes to show that there is some good in the very worst folks. Blacky is a sly old rascal. Usually he is as noisy as any one I know, but he came and went without making a sound. Now I think of it, I haven't once heard his voice near here this spring. I guess if Farmer Brown's boy could find this nest he would get even with Blacky for pulling up his corn. I know a lot of clever people, but no one quite so clever as Blacky the Crow. With all his badness I can't help liking him.” Twice, while Peter watched, Blacky returned with food for Mrs. Blacky. Then, tired of keeping still so long, Peter decided to run over to a certain place farther in the Green Forest which was seldom visited by any one. It was a place Peter usually kept away from. It was pure curiosity which led him to go there now. The discovery that Blacky the Crow was using his old nest had reminded Peter that Redtail the Hawk uses his old nest year after year, and he wanted to find out if Redtail had come back to it this year. Halfway over to that lonesome place in the Green Forest a trim little bird flew up from the ground, hopped from branch to branch of a tree, walked along a limb, then from pure happiness threw back his head and cried, “Teacher, teacher, teacher, teacher, teacher!” each time a little louder than before. It was Teacher the Oven Bird. In his delight at seeing this old friend, Peter quite forgot Redtail the Hawk. “Oh, Teacher!” cried Peter. “I'm so glad to see you again!” Teacher stopped singing and looked down at Peter. “If you are so glad why haven't you been over to see me before?” he demanded. “I've been here for some time.” Peter looked a little foolish. “The truth is, Teacher,” said he very humbly, “I have been visiting the Old Orchard so much and learning so many things that this is the first chance I have had to come 'way over here in the Green Forest. You see, I have been learning a lot of things about you feathered folks, things I hadn't even guessed. There is something I wish you'd tell me, Teacher; will you?” “That depends on what it is,” replied Teacher, eyeing Peter a little suspiciously. “It is why you are called Oven Bird,” said Peter. “Is that all?” asked Teacher. Then without waiting for a reply he added, “It is because of the way Mrs. Teacher and I build our nest. Some people think it is like an oven and so they call us Oven Birds. I think that is a silly name myself, quite as silly as Golden Crowned Thrush, which is what some people call me. I'm not a Thrush. I'm not even related to the Thrush family. I'm a Warbler, a Wood Warbler.”
