Ran across this yesterday. It's not unusual at all to see where a bird has met it's demise when out and about.
I think this is from a Canadian goose. All there was here was feathers and an egg.
I believe this bird actually tried to nest here and the egg was actually layed here.
I did break this open as I was curious. Should have brought it home and ate it. These birds lay 3-8 eggs.
I think this bird for whatever reason needed to lay an egg and was attacked almost immediately and was carried off. This egg was not ripped from the body.
Nature is harsh. In fact my curiosity is up here as this doesn't all make sense. I'm going back down there to look this over again. Fact of the matter is I've never seen a Canadian around here that I can recall.
