I think this is a hybrid Anas casztanea x Anas sibilatrix and have also sent a mail to this site concerning this.
there are several features which suggest that parentage, and there is some likeness to such ahybrid shown in the book hybrid ducks of the Gillham brothers.
but as this is the firsdt time i see such a photo, apart from the Gillham books,
others comments would be valuable.
Maybe somebody can comment here?
Thanks, Jörn
