Here's a hybrid duck we shot today. When I first seen it dead I figured it to be a mallard/gadwall cross. I still believe that's what it is but let's see what everyone thinks. It's different than the greenheads you shoot every once in a while with drake plumage and hen belly feathers. I have heard those actually get that way from hormonal imbalances but I'm not a biologist so can't confirm that for sure. This is all grey down the chest and belly, the wing patch is very dull, the color on the head is different than normal but barely noticeable. Kind of cool because it's the same spot I shot a blonde mallard at last year. I'll include that pic too.
