Watch the Viral Brazilian Bird Bouncing a Golf Ball on a Cart Path
By Elena Rostova
A standard regulation golf ball weighs approximately 1.62 ounces (45.9 grams) and measures 1.68 inches (42.7 millimeters) in diameter. Beneath its ionomer or urethane cover lies a core made of cross-linked polybutadiene rubber, engineered specifically to store kinetic energy and deliver an immediate spring rebound upon impact.
When the seriema drives the golf ball into the concrete cart path, two engineering realities collide:
First, the concrete has an extremely high compressive strength, meaning it absorbs virtually none of the bird's strike energy. Second, the golf ball does not deform plastically or shatter. Instead, it compresses slightly and snaps back, converting the seriema's downward momentum into an explosive vertical bounce. In an instant, the energy the bird generated to crush the object is returned directly toward its face.
To an animal operating on hardwired evolutionary programming, this outcome is completely unprecedented. Snails do not rebound six feet into the sky. Eggs do not launch themselves backward. The seriema's startled hop was a natural reflex against an object that appeared, by all known sensory logic, to strike back.
