A fine up close and personal swan there Dave
surprised you struggle to see the bird though
..I've always thought it was one of the easier monikers to make out
perhaps resembles a duck a little more when viewed through and eye piece
The number of times over the years I've used the "see if you can make out the duck" during outreach observing sessions, is very high
But either way, it does resemble either bird swimming on water.
