Found in a dutch website (http://www.corotauria.nl/afbeeldingen/foto.php?ned=Zwarte Zwaan&soort=Zwarte Zwaan), please look at here three pics of a swan (specified as black swan - Cygnus atratus in the website).
In my opinion, this black swan would be a mute-black swan hybrid, because of following characters: bill coloration, nostrils placement, feather structure, eye coloration, general morphology.
Your opinion?
