The lindworm had often watched the eagle flying about the top of the tree , carrying food to his young ones and , accordingly , he watched carefully for the moment when the eaglets began to try their wings and to fly away from the nest .<br>Of course , if the eagle himself was there to protect them even the lindworm , big and strong as he was , knew that he could do nothing ; but when he was absent , any little eaglets who ventured too near the ground would be sure to disappear down the monster 's throat .
The lindworm is different than the monster.
The lindworm is referred to as the monster at the end of the text. The system probably doesn't register that they are the same.
