Duck, Danube, Serbia (1 Viewer)

This duck was so far photographed by two independent observers. Tends to hide in cover of vegetation, does not like to be photographed. The white undertail points to A.nyroca but the other coloration is unusual. Any ideas?

A. fuligula can show white undertail coverts as well. The rather long, slim shape to the bill and pale 'cheeks' look good for nyroca but the head shape, very blue bill and yellow / cream tint to the lower half of the iris don't seem right. I'm going with an Aythya hybrid, nyroca X ?
