Wing shape was intermediate. the bird was looking more plump than shelduck, but similar size.A similar hybrid was at the Zoo of Basel. I saw pictures of that bird. the only difference to the wangerooge bird was that it had a white head, but with the same black markings as the wangerooge bird. Is that bird male or female? That question was raised on wangerooge, eider being a species with distinctly different plumage in both sexes, and shelduck being not.I am not sure if this is the right forum, but Michael Frankis asked for the drawing-here it is- and so I raised the above question again (the bird was named Rainer-Maria by local birders, as nobody could say its a he or a she)</blockquote>
