Kingfishers Are Master Divers with a Special Beak


The kingfisher, also known as the “flying jewel,” extends its beautiful body in a straight line, takes aim at its prey, and dives underwater at speeds of up to 100 km per hour. Its beak forms a sharp square pyramid to reduce air and water resistance, allowing the kingfisher to dive like a bullet with hardly any splash. This shape exactly matched the one researchers eventually arrived at after using computers to calculate the shape that produces the least resistance. The kingfisher’s long evolutionary history had given it the beak best suited to diving.
