frog legs anyone?

I was thrilled to see the blue heron today. This photo was taken with my zoom lens after which I cropped and enlarged the photo to get this image. The focus could be sharper for sure! Anyway, from a distance I thought that maybe the heron caught a fish, but it looked a bit long to be a fish, so maybe an eel? With the enlarged view it looks like the heron had frog legs (and body!) for dinner.
