If you lived near lake Michigan a sturgeon or salmon could fall on the golf course from a bald eagle who lost his grip. Often another bird is harassing it. Bald eagles are on many coast lines in the US. And they would certainly go after a fish that size. Also, could be an osprey or turkey vulture as well.
Yes, we see them quite regularly here on the Gulf Coast. Saw one osprey dive and catch a big mullet just last month...............
