Flamingos create water tornados to trap their prey

Flamingos have developed an amazing variety of techniques to create swirls and eddies in the water to concentrate and eat brine shrimp and other organisms, a biologist found. They stomp dance to stir organisms from the bottom and concentrate them in whorls. The organisms are then drawn upward by a head jerk that forms a vortex. Meanwhile, their beak is chattering underwater to create vortices that funnel prey into their mouths.
