Every fall when the brown ducks start to fly south some hunters wonder why waterfowl biologists would call these ducks "cinnamons and or bluewings". During the summer and fall phase these ducks usually ALL look like bluewings but if you look close enough you might see a difference.
This shot was taken very early in the morning. I opted for my Canon instead of my cannon!
Example A:
Example B:
This bluewing has a brown eye. You will also notice that most of the time when they are swimming in the water, that their blue patch doesn't show up so much.
Example C:
This is a drake cinnamon. First of all you can see his very red eye. It is even easy for me to tell the difference when I have both to look at. One (the red eye) is much lighter than the other. (I'm color blind)
The only other difference is minute for sure. You would need a caliper to measure the upper mandible of the cinnamon and or bluewing. The cinnamon's upper beak is just a bit wider than that of the bluewing. If you can "think" spoonbill, it will help.
I hope that some of this might help.
