What is the largest prey animal that they have been known to kill?
A. Good question. The key word here is “kill”. Bald eagles are much more opportunists than killers, meaning that if they can get an easy meal without expending much energy (i.e. by killing something) they will do that. So, reports of bald eagles feeding on deer, whales, or other large animals, are usually because they found it/them already dead. Eagles are capable of killing geese, turkeys, swans (especially if they are already somewhat debilitated), and large salmon. I would not be surprised if they took any prey that was under about 3-4 pounds, which would be their max. No type of food item (meat) would surprise me either, except that obviously their favored prey is fish.
