I was chatting with a guy with a scope next to the parking lot south of Milwaukee's Bradford Beach yesterday afternoon. I asked if he'd seen anything interesting in the raft of ducks off of the beach. He said "female Barrow's Goldeneye". He looked around for it for about ten minutes and refound it. I took a look through his scope and it sure looked like a female Barrow's. Head was an overall darker brown than a female , and bill was mostly yellow.
This birder was from Germany, and was headed back home tomorrow. He'd been here on a work assignment for two weeks. Seemed like a pretty serious and knowlegdeable international birder.
That's MilWALKee BIGBY species #191 and 2010 "combo" BIGBY species #230.
