Red-breasted Merganser, Back Creek, Kennebunk ME

I am 99% sure this is a female Red-breasted Merganser from the mouth of Back Creek where it joins the Mousam River in Kennebunk Maine. I used to see both Common and Red-breasted Mergansers in Back Creek and the Mousam every winter, often. In the past few years I not seen any. So I am out of practice on Mergansers. 🙂 I am sure someone will correct me if I am wrong. Sony RX10iv at 600mm equivalent. Program mode. Processed in Polarr.
