Why N America and not Europe or N Asia? I don't remember a difference between 
Gadwalls across these continents regarding their speculum pattern?
Overall jizz, head shape, facial pattern, bill colour, bill shape and speculum 
pattern don't match that of a Gadwall but rather match that of the Mallard 
complex. Gadwall has a sharply defined black and white speculum very unlike 
that of the hybrid mutant monster in question. Thus, I don't think that Gadwall 
is part of this mix. Having said this, it is well documented in the literature 
that the off spring of two duck species (I.e. Tufted Duck x Common Pochard can 
look like Lesser Scaup plus many more examples; see Randler 2001 or Gillham & 
Gillham 1996) can look much more similar to a third species than to either of 
the parents. This certainly complicates the ID of hybrid waterfowl.
Anyway, I am pretty sure that this bird is a human-influenced mutant on top of 
the hybridisation issue. Therefore my ID 'barnyard-type" Pacific Black Duck x 
Mallard hybrid.

Probably beyond the Pale, but in N America the speculum would look like a 
Gadwall.       -TATE
