One last point to add on Common Goldeneye with this much color on the bill,
they usually do not have the black nail. I think I read that in Pyle last
winter when an odd one was in PDX somewhere.
I think if you study the shape of the lower bill on Goldeneye, you can what
I call a smile on the Barrow's. The Common is more poker-faced
looking...due to the up sweep in end of bill, larger nail and structure at
the base. I can't always see it, but often enough.

Hi All,
Chris Chappell made available the following ID article by David Sibley on
IDing female goldeneyes. I found it quite useful, going more indepth than
the typical field guides.

barrows-and-common-goldeneyes/
Bob Obrien mentioned a key point in head shape being affected by the
active, diving bird, thus showing a wet head, giving it a less sloped
appearance. The other key point for me at least, was the article
explanation and sketch on bill shape (very subtle), something I don't think
that could be seen on this bird very well, but in studying my photos, it
can be seen. I should say one of my photos, when enlarged on the camera,
shows the Barrow's bill shape.
I encourage readers wanting to become more experienced to read the
article. You might learn more to help you in your IDing.
Thanks for your comments.
