there were when i was a falconer's apprentice, many many many more keepers inside, and just outside of london, and other major cities across the pond, than there were big keepers of BOPs and often described catching many caught wild ones to pick through to use. most falcons here, were brought originally from english settlers, and many document depict and describe falconry from the area, and how wild falcons often escaped or were released. also many of the shows they show about peregrine falcons show them in london or new york ect and other major cities as best places that they condense and nest in large numbers because of abundant and natural like easy prey and architecture very good and similar to natural environment. the white doves in any less than flock of half dozen are especially easy prey because stand out from color, but then again so many racing pigeons fly so often with no trouble, they may still have an edge if your one makes it back. i have a male roller a prized cock that i keep letting out with my others after say never again, and each time he is immediately targeted by a peregrine, and rolls out when hit, but then hides from a day to week before coming home, even when release the flock and his mate/s. so maybe she will return, or even if injured heard of some on here who rescue then heal up and release then homers go home, so maybe in week to month she will just pop back up, depending on her homing instinct. good luck!
