A Fish Tree?

Rounding a curve in the trail, we looked up (for birds of course) and instead saw a fish. Apparently one of the birds, we assume an Osprey, caught a fish wrapped up in fishing tackle. With the hooks and weights, maybe it dropped it rather than attempt eating it? It hung quite a way up the tree, so we doubted a human prankster did it. It caught our eye, and that of several hikers as they came up on it.
