In the winter, one of the problems of deciding whether or not the red breasted merganser that you are observing is a female or is it a first-winter male. After I researched the subject, the way to tell the first year-male from a female red-breasted merganser, is that the first-winter male red-breasted merganser as a black ring around its eye, while the female red-breasted merganser has whitish eye crescents.
