It is an interesting thought but for the sake of brevity I did not include all of the details in my post. Every time I have seen this happen it was when an osprey was being chased by a bald eagle. They did not want to drop the fish but they had to in order to use their talons to defend themselves. So, I don’t think it was intentional to drop them in the lake. At another location I have found fish in the middle of a baseball field presumably dropped by osprey as well under similar situations.
