I believe this is a juvenile American Herring Gull with a blue crab. I spotted this in New Jersey.
American herring gulls , according to All About Birds, eat fish, insects, smaller seabirds, and even feed on adults, young, and eggs of other gulls. They also take mussels, crabs, sea urchins, crayfish, clams, and mussels.
I was hoping to go back to the same spot this weekend, but alas a nor’easter has affected the weather prior to its arrival. Maybe another weekend coming up I can swing it. We are predicted to get much needed rain, however, hopefully not too much. Have a Happy Sunday!
