Thanks to @moonmtn I now know he is a black necked swan. My bird book makes the black necked swan look entirely different but Google was spot on! Clearly he is in breeding plumage. The water was pretty funky so I gave it a bit of a seeing to in Topaz Simplify.
Thanks for your visits, comments suggestions, favs
I think it is a black necked swan. We saw a lot of these birds when we were in Chile. You should google it. Love the water in this photo and the reflection of the swan.
