Peregrine falcons are birds of prey that dive and catch their prey out of the air. These birds can dive up to 250 mph! Peregrine falcons are able to do this by gaining height, tucking their wings in, and diving down. As they tuck their wings in, it makes the falcon aerodynamic. This means that the air around the bird moves smoothly. This allows the peregrine falcon to dive at super-speed! This is how peregrine falcons dive so fast!
