My family has a summer “camp” on Islesford, just below Mount Desert Island. Our house is situated on a quiet cove, where we frequently see eiders, loons, eagles and herons. One quiet afternoon, a raft (group) of eiders were swimming along in the middle of the cove with several ducklings in their midst, when along came two eagles, hungry for an eider snack.

The two eagles were furiously dive bombing the raft, but just as each got close to a duck, the entire group would turn bottoms up and dive underwater. By the time the ducks resurfaced, the eagles had recovered from the dive and were well above the water, unable to snatch any ducks.

This went on for some time, with the eagles relentlessly swooping down to no avail. They finally gave up and flew off to a nearby outcropping of rocks at the outer edge of the cove. Relieved that their tormentors were gone, but still cautious, the ducks continued in their usual affairs. Meanwhile, I watched the two eagles, side by side on the rocks, presumably resting.

All at once, one of the eagles flew high into the air again and started dive bombing the raft once more — only the eagle appeared to be doing it somewhat half heartedly, rarely getting closer than 5 or 6 feet above the water before ascending again. The ducks weren’t taking chances, however, so they kept diving underwater all at once, then popping back up when the coast was clear.

This went on for a bit when I suddenly noticed the second eagle flying low and slow along the surface of the water. Miraculously, those eagles timed things so that just as the “bomber” eagle made its dive, and the ducks went down, when they popped back up, there at the surface was the other eagle, which they never saw coming. It effortlessly snatched a duck out of the raft, then flew to the rocks. Its companion followed, and together they feasted.

I have never seen birds hunt with such coordination like that. They earned that meal.
