观察细节
Photos of a continuing hen plus a new hen. One hen's plumage is darker and more smudgy overall, and you can see various other differences in color patterns between the two. However, both show definite MALL and ABDU influences on bill and plumage. (The lighter hen is alone in two photos, and the darker hen is with a Mallard in the third photo.)
