On November 13th and 14th at Songdo Lagoon, aka Namdong Reservoir, Incheon, a curious aythya duck was seen and photographed (below) by Mr Spike Millington and John Clark. It was described as showing a prominent white wing-bar in flight, and was identified as a first-winter male Baer’s Pochard. I have sharpened the image slightly.
On November 17th at the same site, a duck – presumed to be the same individual- was photographed by Dr Shim, Kyu-Sik (below).
Opinions and discussion as to the identity of this intriguing bird are welcomed!
