That is an amazing picture.
Once watched a life and death dog fight between a Bald Eagle and a Seagull on the Gorge in Victoria for about half an hour. The Gull would fly fast and erratic about a foot above the water. The Eagle would dive on the Gull and just as it was about to grab the Gull, the Gull would fold its wings and crash into the water with a splash causing the eagle to overshoot. The eagle would then have to climb again so it could dive once again on the Gull. This gave the Gull time to shake off the crash landing and get air born where the process happened over and over. Unfortunately I never did get to see the final outcome because the aerial combat eventually went around a point of land and out of sight.
I suspect if the Gull had been caught not aware of the eagle and flying more than about a foot above the water it would have been quickly toast.
