I had an osprey grab a hickory shad I was fighting and try to fly off with it. After about 30 seconds or so he let go. But, boy was he pissed when I let that shad go. (Closed season for us humans.) I used to have a picture of the shad with the talon marks across it's back. One morning I had a big old owl swoop down on a white buzz bait I was fishing. He got almost right on top o fit before he flared and flew off. I'm not sure whether he figured out the buzz bait wasn't edible or it was just getting too close to the boat.
