A Black-crowned Night Heron in Succotash Salt Marsh skulking among the spartina.
A pair of Great Black-backed Gulls playing tug-of-war with an American Eel. The one on the right had it half swallowed while the left one had a grip on the tail. Don't know how long they were at it, but I watched for at least 5 minutes. Eventually the one on the right won, but only because another bird flew down and disrupted the battle.
