Mr Swan?

I went for a few messages (Tiso, Ocean Terminal, etc) and noticed the three adolescent cygnets with this guy - tried to get a clear shot of his leg ring but with no luck. No further updates on the female who's been self-isolating (I didn't realise swans did that) upstream a bit. Her plumage seems to have been damaged by some pollutant. Hope she recovers, since it was only last year that her predecessor female died.
