All that day Peter remained hidden in that hollow log. He did not dare put foot outside until the Black Shadows began to creep through the Green Forest. Then he knew that there was nothing more to fear from Terror the Goshawk, for he hunts only by day. Once more Peter's thoughts were chiefly of his stomach, for it was very, very empty.

But it was not intended that Peter should fill his stomach at once. He had gone but a little way when from just ahead of him the silence of the early evening was broken by a terrifying sound--"Whooo-hoo-hoo, whooo-hoo!" It was so sudden and there was in it such a note of fierceness that Peter had all he could do to keep from jumping and running for dear life. But he knew that voice and he knew, too, that safety lay in keeping perfectly still. So with his heart thumping madly, as when he had escaped from Terror that morning, Peter sat as still as if he could not move.

It was the hunting call of Hooty the Great Horned Owl, and it had been intended to frighten some one into jumping and running, or at least into moving ever so little. Peter knew all about that trick of Hooty's. He knew that in all the Green Forest there are no ears so wonderful as those of Hooty the Owl, and that the instant he had uttered that fierce hunting call he had strained those wonderful ears to catch the faintest sound which some startled little sleeper of the night might make. The rustle of a leaf would be enough to bring Hooty to the spot on his great silent wings, and then his fierce yellow eyes, which are made for seeing in the dusk, would find the victim.
