The duck in the rear of the picture of six looks a whole lot like yours, so maybe a hybrid? If you can’t use bill size or color, or forehead slope, what’s left? They should come with ID tags!

I just posted on Advanced Bird ID Facebook so will see what they say. Here and here are two articles by Sibley on ID of female goldeneyes. Bill size is not a good indicator and neither is the slope of forehead because water will change the slope.

The shape of the bill is important.

The bill of the one in question may even be a little larger and slopes differently, at least to me. I wonder if there was a Redhead in the family closet?

One thing to keep in mind on these photographs, the one with the yellow bill was actively feeding while the definite Common was resting and had not dove much. I am not sure if that created the illusion of the Common having a bigger head as the Barrow’s/Common had a slicked back look.

More photos will undoubtedly be coming from other folks. I am on the fence myself but hope people keep an open mind and check some of the photos that will be coming.

Barrow’s has a steeper forehead, and stubbier bill. In Alaska, I use those instead of color. While color could vary, I guess, I’m not sure skull shape would, or bill size. Neither forehead looks “steep” and the bills look relatively close in size.

Hello Folks,

Possible Barrow’s swimming with a Common Goldeneye at Fort Fisher, NC in the Aquarium Pond off the Basin Trail.

Pictures at below ebird link. Of note was the all yellow/orange bill and a warmer chestnut brown color which doesn’t come off nicely in the pictures but myself and two others both noted in the field.

Sibley’s has a paper on this ID which is tough on a female Goldeneye. Apparently bill size overlaps and Common can have a yellow variant although in November it would be pretty rare. Bill shape needs to be closely considered.

I think Derb is on his way down to check.

There was a guy with a 600mm lens taking great shots, I will see if I can get him to send some pics.
