I agree with your identification as female. I have watched quite a few young male Red-breasted Mergs molt into more definitive plumage, and this date is very late for one to be in full imm. plumage. The scruffiness overall suggests to me a first-cycle female.

Following up on Dave Irons’s post this afternoon about Fernhill Wetlands merganser sightings, attached is the female Red-breasted Merganser I found on May 19 while doing weekly spring surveys for Audubon/Clean Water Services. I posted a message to OBOL about it that morning.
The reason I called this a female as opposed to an immature male is that imm males can look much like a female but will have some black surrounding their eyes, unlike this bird. There is also a pale line under the eye, another feature that would distinguish it from a young Hooded Merganser. The bill is longer and more orangey red than the latter.
