Black stork parachuting toward the nest on height

　The black stork landing on the nest on height does not take the way of throwing up landing but uses the flapping down in emergent temporal stop after the parachuting flight, the same as the landing on a flat ground. This way may be better to land steadily on the fixed position with slow speed for black stork, that has the comparatively small load per wing area, the long and thick bill, the long arm and the split wing. To have bent down the both wings is better to increase the drag and to keep the stability and the steerage. The hanged long legs and the long and thick bill are also better to shift down the center of gravity and to increase the stability, and to land by using the spring of the legs. (Prod.
