Peregrine Falcons are probably the fastest animal on earth. At speeds estimated to around 190mph Peregrines dive on other birds, wings almost closed. If the impact of the mid-air collision doesn't do the job then the razor sharp beak delivers the killing stroke.
Peregrine Falcons normally pair for life. They normally nest on rock ledges, such as in inland crags and sea cliffs, but increasingly they're seen in towns and cities where they nest on tall buildings such as tower blocks and cathedrals.
