I meant to add some context. Every day there are several thousand crows, both fish and American, that cross Vineyard Sound from Falmouth to roost for the night. The photo is a group that passed by and are now out over the water. I heard them calling so ID'd them that way.

This group of 2-3 ravens keeps visiting MBL, sometimes multiple times per day. They fly in and attract the attention of the resident crows. There is some scuffling and the ravens generally fly off - only to return later.
