Which animal moves fastest through the skies?
The cheetah is well-known for being the fastest creature on land, but the animal kingdom is not limited to Earth's surface. What is the fastest flying animal? And what biological features enable its speed?
Peregrines hunt for prey from great heights, either from the air or a high perch. When they find a target, they plummet at high speeds, attacking with a clenched foot to stun or kill prey with the impact, Hein van Grouw, senior curator of London's Natural History Museum's bird group, told Live Science in an email.
Peregrines have muscular, teardrop-shaped bodies that also help streamline the birds to"reduce drag and help it drop like a bullet," Drewitt said. In addition, their feathers are remarkably tightly packed and stiff in structure when compared with other falcons,"probably to reduce drag and make it go more smoothly through the air," van Grouw said.
