The peregrine falcon is a very fast flier, averaging 40-55km/h in travelling flight and reaching speeds up to 112km/h in direct pursuit of prey. During its spectacular hunting stoop from heights of more than 1km, the peregrine may reach speeds of 320km/h as it drops toward its prey. The peregrine falcon is one of the most widespread birds in the world. It is found on all continents except Antarctica, and on many oceanic islands.
