Peregrines are known for their speed, reaching over 200 miles per hour during a hunting dive (called a stoop) at which point their prey are killed instantly.
Peregrines' habit of preying on waterfowl have also given it the name "duck hawk."
Peregrines can be preyed upon by great horned owls, gyrfalcons and even other Peregrines.
Peregrines nest on ledges or rocky outcrops. They have adapted well to living in cities, which offer tall buildings with ledges, as well as water sources and large populations of prey (pigeons and starlings).
