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.
