Aye, the bald eagles are ubiquitous. They fly off the river and follow the ducks out to feed. I had one try to pick up a dead duck on me the other day but for some reason he dropped it. A year ago I had a snowy owl attack a wounded goose. It made the best of the goose. Many years ago while hunting ducks over a pond I saw a merlin grab a killdeer out of mid-air. The killdeer was quite unhappy as it squawked mightily before it died. I suppose I am lucky to see these events but I do spend many days afield.
