9. Greylag goose (Anser anser)

And it's the last of the grey geese, greylag goose, classic goose. I tried to do this one a bit more loosely and quickly without obsessing so much over detail which I am wont to do. Also I was a bit short of time.

I've made the wings a bit too short and round.

White domestic geese are descended from greylags so you often see interbreeding between the two, leading to all kinds of weird and wonderful results:

50 shades of greylag. Yep I went there.
