Pigeons are the peregrine equivalent of Kraft Dinner I think, they only seem to eat them with they have kids or pickins are slim. (And yes, I like KD from time to time) Speaking of feeding, what you see Princess and Trey bring in are not whole birds, they have had a nibble on them before they arrive. Usually head, wings, tail are gone. Sometimes leg. Just bringing the good stuff since they have to fly it in and they want to bring as much as possible for the chicks. At this stage they are ripping off tiny little pieces for the chicks, but that will change, almost day by day, as the chicks grow.
