Yesterday, March 12, 2018, we were near the Power Plant at the Cape Cod Canal. Someone had thrown some large pieces of bread on the sidewalk and there were gulls trying to get a bite. There were also two Ravens trying mostly successfully. The Ravens appeared larger than the Herring Gulls and were very aggressive toward the gulls dominating the stealing of bread. One Raven picked up a large piece (looked like a sub roll) and flew off with it in its bill. While in flight, the Raven transferred that roll from its bill to it talons after taking a big bite. At that point, a Herring Gull attacked and the Raven dropped the roll but went back to the sidewalk to get another pushing all the gulls out of the way aggressively.
I was impressed by the size of the Ravens relative to the Herring Gulls. Altho Sibley gives length of Herring Gull as 25" and weight 1150g and Ravens as 24" and 1200g, the Ravens appeared much heftier and larger than the gulls to me.
Did not see the alleged King Eider from the Sandwich side but there was a large concentration of eider and three species of scoter just off the beach there.
