Anser cygnoides | In the "Wildlife Survival Zone", they took the former Demoiselle Crane habitat, not sure where the Cranes are but they're not on exhibit anymore
This species has such an odd head shape. Its so elongated. I was happy to be able to capture it with its bill open like that. This was one of several points in my visit where it lightly rained so the way it made the lake surface look adds to the drama quite nicely I think.
