Peregrine Falcons

March 09, 2015 Posted by: JG - Entrance Station Ranger (Arch Rock)

The peregrine falcon is the fastest animal on earth. Soaring hundreds of feet in the sky, the peregrine falcon uses its keen eyesight to spot smaller birds, such as waterfowl, doves, and song birds. With its prey in sight, the peregrine falcon will fold its wings back, and dive towards its target. Reaching speeds of over 200 MPH, faster than a NASCAR racer, the peregrine falcon snatches its prey out of mid-air.
