i'm the greatest duck in the world!

Easy at first try, then very difficult with some try and see not possible.
At the end a bit og educated guess.
Thanks.

Too many "1"s with no particular place to go!

Wow, I figured it out with a bunch of one time guessing. Just have to keep in mind what a duck's supposed to look like.

Hint for the wing: Fill R12C8, R13C8-9, R14C9, R15C10.

9 ambiguous pixels, a 50/50 around the beak, and the rest on the wing and chest.

10 solutions.
