Wild Moves: Raptors
Athletic animals take our breath away, but for sheer awe, nothing beats the miracle of bird flight--a feat that requires more strength than any other form of locomotion. It starts with the pectoral muscles on a bird, which generate more than 80% of the power needed for a wing stroke. Small wonder then, that the wings can account for more than a 1/3 of the bird’s weight. Add a light frame built on a foundation of hollow bones and fused vertebrae for stability, and the result is an aerodynamic delight--best appreciated in super-slow motion.
