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!

A great but sad (for the crab) photograph.

Nice timing, Sharon. I agree, it is sometimes tough to see “nature in action”.

Great photo. They also steal anything not nailed down. Watch out for your lunch at the beach! Can’t argue with how successful a species they are.

I’m sure they would. I was with a friend in a seaside town in England as we were coming out of an ice cream shop my friend got one taste of her ice cream before a gull swooped in and made off with the whole thing. Not sure what kind of gull it was but you could not eat outside there.
