Looks like a hybrid to me, but the black on the crown is not wrong for White-headed Duck. The body colour and white undertail coverts do indicate Ruddy Duck.

I think it is a hybrid.

White headed Duck with characteristics not shown in bird guides

Thanks all for trying. I think this is an interesting bird, despite all the characteristics I have numbered to show it’s an hybrid, this is fortunately an adult male White-headed Duck according to Carlos Gutiérrez Expósito and others who have commented on the bird.

On the other hand, I think that bird guides doesn't show (neither in texts nor in illustrations) that some White-headed Ducks have pale undertail coverts as shown in this bird.
