Prey. This is a term in falconry. When a hawk struck the object of pursuit and clung to it, she was said to bind; but when she flew off with it, she was said to carry. The carry or quarry, therefore, means the prey carried off by the hawk. It is an error to derive this word from the Latin quro (to seek).
