Who took Gulliver from Glumdalclitch?

An eagle snatched Gulliver's box.

I heard a noise just over my head, like the clapping of wings, and then began to perceive the woful condition I was in; that some eagle had got the ring of my box in his beak, with an intent to let it fall on a rock, like a tortoise in a shell, and then pick out my body, and devour it: for the sagacity and smell of this bird enables him to discover his quarry at a great distance, though better concealed than I could be within a two-inch board.
