Wood pigeons appear in my garden every spring just when the cherry blossom is about to burst forth on my trees. The winged scavengers proceed to eat as many buds as they can before the buds develop into leaves and blossom. As a consequence, my cherry trees have many bald spots amongst both the blossom and the leaves. There's a pair of peregrines visit the cliffs, but I can't convince them to patrol my garden!
