The gulls were taking advantage of the river's low water level and resting or searching for food along the gravelly ridges.
I'm not sure, but the larger bird with the salmon might be an adult Herring Gull and the other one a Ring-billed Gull. Look at how the smaller gull stealthily eyes that excellent fish. Does she dare go closer.Just a little morsel, please.
I did some research and found out that the red spot on the Herring Gull's lower mandible "serves as a target for the young". The chicks peck at this spot and "the parent instinctively feeds it by regurgitation". Source: Bird Guide
