Taking a look at a Canada Goose, you may not suppose their our bodies are designed for fancy flying. However watch as a flock of geese is available in for a touchdown at a lake and also you is perhaps shocked.

If the flock is available in too quick or too excessive above the water, geese have a little bit trick to sluggish themselves down for a protected touchdown. The geese cease flapping after which shortly roll their our bodies the other way up, whereas twisting their lengthy necks the correct method up. Lastly, they rotate once more to proper themselves simply in time to softly splash down.

It’s a maneuver known as whiffling. The trick appears to let the geese quickly lower their velocity and altitude. It’s a bit just like the flaps on the wing of a passenger jet that stretch to sluggish the airplane down, however far more dramatic.

A number of goose species and a few geese have been seen whiffling, in addition to a lot smaller shorebirds corresponding to yellowlegs and godwits.

Whiffling would possibly assist migrating geese fly quick till the final doable second. Or it might simply be for enjoyable. It seems that geese are constructed for velocity and tough maneuvers.
