captive Wood Duck x Bufflehead hybrid, Netherlands - copyright Joern Lehmhus
(illus. ID: 2437)
The photographer of this bird didn't know its parentage, but Joern points out:
"Wood duck traits are obvious and the other features indicate the second parent to be a short-billed white-flanked and pale- or white-breasted bird. From bill and eye coloration a dark-eyed, grey-billed bird appears also likely. All these features point to Bufflehead."
