Cherry Creek State Park, Colorado
I was photographing eagles when I noticed a ring-billed gull nearby fighting with something in the water. It turned out to be a dead fish floating on the surface but it was a little large for him - but he was determined. Two eagles saw the struggle and came in to steal the fish. The gull flew off with the eagles in pursuit. That was the moment the American white pelican saw an opportunity to steal the fish.
