Why do Phalaropes spin?
The birds twirl on the surface like little ballerinas, spinning and pecking, again and again. As it spins, the phalarope forces water away from the surface, causing an upward flow from as deep as a foot below. And with this flow comes food. Little animals, like tiny fly larvae, are forced to the surface.
