The eagle would fly up, only 10 or 15 feet, then dive again at the duck, over and over. I wondered how long this standoff could go on? Then, the duck made a break for it, flying away over the water as fast as it could.

The eagle put it in overdrive, and went right after it in an aerial chase! Just when I thought the eagle would catch it, the duck dived right out of the air, straight under water. Then the same swoop - dive - swoop - dive scenario resumed. I thought it might go on for most of the day, till the duck's worst nightmare happened. A second Bald Eagle showed up. Now, the two eagles would alternate their dives, and clearly the second one would try to be there just when the duck popped up again, unable to stay submerged.
