Owl Pellet

I was out on the first bird walk of the year at Allens pond Massachusetts Audubon sanctuary in Westport, Massachusetts. The walk was interesting in that we found a number of signs of either Hawk or owl predation. There was remains of a rabbit with a lot of fur around and a partially eaten eider. We also found a large owl pellet on a rock. It measured about 2 inches long and about an inch and a half in diameter and was bigger than the usual owl pellets that are found. There had been reports of a snowy owl in the vicinity. Was this it's pellet?
