Jon Beresford, one of BAR's founders, said finding a peregrine on the ground was unusual. So I suspect during her first trips from the nest flying, she's come a cropper, she's hit something," he said. It was found the bird was the offspring of a male peregrine successfully treated by BAR last year. "It's a privilege not only to treat such a magnificent bird as a peregrine falcon, but also to release her and see her fly again so well," he said. "It really brought tears to our eyes," said Beresford.
