Interesting to see the mix of birds coming for a snack--Mallards, Mute Swans, Black- headed Gulls, Herring (I think) Gull, Rock Pigeons. Sorry, but I think I liked my Mute Swans in the wilds of Michigan!
Brave man to let swans get so cosy. Like Gail, I'd probably wear throw away shoes, or hose-downable rubber boots, and heavy gloves on my hands.
I do love this shot of the waterfowl taking over the boat launch and mooching for handouts.
