As luck would (finally) have it, I was prepared as these two went at it in Rausu, Hokkaido, recently (more of the trip in the link below). The light was lower than the day before so I was shooting at 1/1000 and ISO 1600 so perhaps a bit faster might have been better (when viewing at 100%
). The white-tailed eagle has the Steller's sea-eagle by its bill and is about to slam its head to the ground beore letting go - the fight was about 3 seconds at ~5 fps with a Canon 5DsR and 100-400v2 with 1.4xV3 at ~200 mm and f/11 for DoF. I had decided to shoot jpegs for the action series, mainly of eagles swooping in to pluck fish from the sea. The frame here is cropped a bit (I had widened the FoV to keep them in the frame as they thrashed around) but is about 30MP. (The island in the background is currently occupied by Russia as one of the disputed Kuril islands.)
