Mallard x American Wigeon is a well-known hybrid with many documented records. Why do you think Baikal Teal is involved in that last bird?
Sorry about the M x AW. I didn't know about that though I suppose it is the first documented record in Japan. The Baikal Teal is definitely involved, because the black lining on the head and light yellow shades represent only Baikal Teal out of the Waterfowl that come to Japan.
