Geese Flip Upside Down to Brake...
"During flight, geese can twist their necks to flip their bodies upside down, while keeping their heads upright."
"Known as whiffling, the move is often performed before landing as a means of braking. Upside down wings generate more drag causing a goose to slow down quickly, just like what happens when a plane is inverted during flight." New Scientist TV: Goose flying upside down captured in slow-mo movie
