What bird are pigeons most scared of?

Pigeons are most scared of birds of prey that hunt them, especially hawks and falcons that are their natural predators, because these raptors are fast, agile, and can catch pigeons in flight. Among raptors, Peregrine Falcons are particularly feared by pigeons, as peregrines are the fastest birds in the world, diving at over 200 miles per hour to catch pigeons in mid-air, and they often hunt pigeons in cities where pigeons are abundant. Cooper's Hawks and Sharp-shinned Hawks are also major predators that hunt pigeons in urban and suburban areas, using surprise attacks from cover. Goshawks are feared as well. Owls, especially Great Horned Owls and Barn Owls that hunt at night, are feared when pigeons roost at night. Pigeons have evolved to recognize the silhouette of raptors and will show alarm and flee when they see a hawk or falcon, often flying in tight, erratic flocks to confuse predators. They are also scared of fake predator decoys like owl and hawk statues, though they quickly habituate if the decoy does not move. In addition to birds, pigeons fear cats, raccoons, and snakes that can reach nests. So while pigeons have many predators, peregrine falcons and accipiter hawks like Cooper's Hawks are among the most feared due to their speed and specialization in hunting pigeons in urban environments.
