Description of the Bird

Medium sized duck with clean, pale gray back and flanks and blackish tail feathers and undertail coverts, Obvious white spots on femoral tract and on side just below folded wing. Orange-pink-reddish breast and dark cinnamon-red head with buffy forehead. Light blue-gray bill with black tip. Small green patch behind eye

Similar Species Discussion

Only real similar species is male AMWI x EUWI hybrid. Eliminated by pure gray flanks with a clean border with the breast, and a uniformly chestnut face, excepting the green eye splotch. small amount of green behind eye is apparently fine for EUWI with pure ancestry. Hybrid would have more of a green stripe, and flanks and back would be less clean gray, more washed with reddish

Resources Used

None at the time. Sibley's guide and several internet fora consulted after green patch was mentioned as a possible hybrid trait

Previous Experience

I see hundreds if not thousands of AMWI each year, and have seen a handful of EUWI in CO and OR
