pair of bald Eagles at sunset

I photographed this pair of Bald Eagles years ago on trip to the Blackwater National Wildlife Refuge in Maryland. I was using a Canon 1D mkIII with a 400mm DO lens with a 1.4 X Teleconverter. The Canon 1D mkIII had 1.3x cropped sensor so with that and the 1.4x teleconverter it was like using a 728mm lens view.
