Here’s why evolution pushed this predator to such terrifying extremes.gettyFew animals will make you reconsider the limits of biology quite like the peregrine falcon (Falco peregrinus) does. Based solely on appearance, it’s a modest bird. It has blue-gray feathers, dark eyes, a hooked beak and a body that weighs barely more than a loaf of bread. And yet this bird performs one of the most violent feats in the natural world. During a hunting dive, peregrine falcons can exceed 240 miles per hour (386 km/h), which makes them the fastest animals on the planet. And at those immense speeds, the world becomes a physically punishing place. Air pressure intensifies. Even the tiniest of steering errors could result in catastrophe. A direct collision would be instantly fatal. And yet peregrines routinely survive dives that would likely destroy almost every other flying animal on Earth.Of course, the falcon didn’t evolve into a feathered missile because evolution “likes” excess; every part of this dive serves an essential survival-related purpose. It’s a carefully refined hunting strategy shaped by physics, anatomy and millions of years of aerial warfare between predator and prey.Why The Peregrine Falcon Dives So FastPeregrines are bird hunters. Their prey includes pigeons, ducks, shorebirds and starlings — fast, agile fliers that are capable of making sudden evasive turns. To catch another bird in the open air is an extraordinarily difficult feat; to catch such nimble birds is even mo...
