He's doing his bit to keep the grass on the river bank nicely clipped.   
Apparently the lone Swan that had been around for several years had to be taken away by the RSPCA because he was lame and now we have two new ones who have taken over this stretch of the river.   They are getting used to us and Luna sits and watches them but neither she nor they seem to be bothered by each other.
Another sunshiny day but cloudier of late with a very lazy wind (goes through you rather than round you). !!
