Peter remained right where he was until at last he saw Redcoat spread his black wings and fly to another tree. From tree to tree he flew, resting a bit in each until he and Mrs. Tanager disappeared in the Green Forest. “I knew Farmer Brown's boy would help him, and I'm so glad he found him,” cried Peter happily and started for the dear Old Briar-patch. CHAPTER XXIX. The Constant Singers. Over in a maple-tree on the edge of Farmer Brown's door yard lived Mr. and Mrs. Redeye the Vireos. Peter Rabbit knew that they had a nest there because Jenny Wren had told him so. He would have guessed it anyway, because Redeye spent so much time in that tree during the nesting season. No matter what hour of the day Peter visited the Old Orchard he heard Redeye singing over in the maple-tree. Peter used to think that if song is an expression of happiness, Redeye must be the happiest of all birds. He was a little fellow about the size of one of the larger Warblers and quite as modestly dressed as any of Peter's acquaintances. The crown of his head was gray with a little blackish border on either side. Over each eye was a white line. Underneath he was white. For the rest he was dressed in light olive-green. The first time he came down near enough for Peter to see him well Peter understood at once why he is called Redeye. His eyes were red. Yes, sir, his eyes were red and this fact alone was enough to distinguish him from any other members of his family. But it wasn't often that Redeye came down so near the ground that Peter could see his eyes. He preferred to spend most of his time in the tree tops, and Peter only got glimpses of him now and then. But if he didn't see him often it was less often that he failed to hear him. “I don't see when Redeye finds time to eat,” declared Peter as he listened to the seemingly unending song in the maple-tree. “Redeye believes in singing while he works,” said Jenny Wren. “For my part I should think he'd wear his throat out. When other birds sing they don't do anything else, but Redeye sings all the time he is hunting his meals and only stops long enough to swallow a worm or a bug when he finds it. Just as soon as it is down he begins to sing again while he hunts for another. I must say for the Redeyes that they are mighty good nest builders. Have you seen their nest over in that maple-tree, Peter?” Peter shook his head. “I don't dare go over there except very early in the morning before Farmer Brown's folks are awake,” said he, “so I haven't had much chance to look for it.” “You probably couldn't see it, anyway,” declared Jenny Wren. “They have placed it rather high up from the ground and those leaves are so thick that they hide it. It's a regular little basket fastened in a fork near the end of a branch and it is woven almost as nicely as is the nest of Goldy the Oriole. How anybody has the patience to weave a nest like that is beyond me.” “What's it made of?” asked Peter.
