Super interesting Andrew. And this is the sort of thing I was hoping someone would reply with. It seems what actually makes a Grey Duck a Grey Duck is lost in the nether nether. BUT the Green speculum with the super fine white trim would seem to be their squadron insignia and I think that should be the starting point at the very least. Beak colour between sexes is an interesting idea too as is the much thicker eye stripe which is something I hadn't looked for.
I guess I just find it an interesting topic and I think its a really good one to throw back and forth. I guess I like the idea that the ONLY colour on a pure Grey Duck is GREEN...and anything else is mallard influenced but your above photos throw a big spanner in the works of that theory unless I cling to my belief that the NZ sub-species (not official) don't have no orange
