I never found either this or the Northern Shrike return to such prey for food. I have seen them alight on the same thorn bush afterwards, but never made any use of this kind of food.
I really believe that you grow up a certain way in New York. There's a New York morality, a sense of loyalty. You know how to win and lose. There's a thousand kids outside, you know who to push and who not to push. There's a sixth sense you develop just because it's New York.
