On the slick ice the feet and tail fail to stop the sliding.
Now the backward beating of the wings are not much help.
So the one being attacked decides to jump over the sliding one.
Then it settles down on the other side of the slider.
One of the most interesting aspects of the relationships of these beautiful birds is the submission of one to another. The female will often get between the two fighters and it ends when her mate submits to her demands. When two females are fighting, the male will stop it by getting his mate to submit to him.
Just another wonderful day in the wilds of Idaho.
