The advent of these animals has also drawn a predator, as Peregrine falcons have also been known to nest in urban areas, nesting on tall buildings and preying on pigeons. The peregrine falcon is becoming more nocturnal in urban environments, using urban lighting to spot its prey. This has provided them with new opportunities to hunt night-flying birds and bats. Red foxes are also in many urban and suburban areas in the U.K. as scavengers. They scavenge, and eat insects and small vertebrates such as pigeons and rodents. People also leave food for them to eat in their gardens. One red fox was even found living at the top of the then-partially completed Shard in 2011, having climbed the stairwell to reach its temporary home some 72 stories above ground.
