Once I was lucky enough to watch this irl. An Osprey had caught a fish and was flying off when a bald eagle flew at the osprey and started swooping at it. The osprey dropped the fish and the eagle caught it mid air, then the osprey went on the offensive and got the fish back. It went back and forth like that for a couple minutes before the eagle finally flew off with the fish. They never once dropped the fish, just kept catching it mid air. One of the coolest things to get to see. Wish I had video of it, but this was before phone videos were worth bothering with.
