"Why do you call him a robber?" asked Dick.
"Because he doesn't mind stealing. The old codger will watch a hawk catch a fish, bird or small animal, then sweep down, and the meal changes hands."
"Or changes claws," smiled Dave.
"That's it. He's a sneaking rascal. Always watching his chance to let other birds work for him. There he is now!"
Ahead, the forest opened out. Into this the eagle was sweeping, in a long, graceful curve, his wings scarcely seeming to move. The four instantly detected his object. A frightened rabbit was scampering for dear life through the grass, headed for a thicket.
But the woodland drama was soon over.
"He's got it," cried Dick.
With lightning speed, the bird overtook the fleeing animal; then the struggling bunny was borne aloft in the eagle's claws, and almost before the boys realized it, bird and prey were but a speck in the sky.
"Gee whitaker, that happened quickly," said Bob.
"Makes me feel glad that there are no rocs around," laughed Dave.
