Hi Jim,
"Holy crap on a cracker" as Penny in "The Big Bang Theory " would say.

That is a humongous crop!!
I think that the crop size is 90% of the problem here. Also you must have done some cloning as well as serious blurring.I think all these things have lead to this problem.
For me, ( and I am not saying this to be mean) this would be a delete because it is just too small in the frame and not a great BG. You don't need to upgrade your gear, you just need to get closer.
It will be a lot cheaper to buy a Kwik Camo blind than buy a new camera. I always think that Tiger Woods can still shoot a 70 with crappy clubs or a million dollar clubs!
Also, I would never reduce the exposure on the entire image for just a bright beak. Far better to burn the beak only.
