You are right!
I used to see Dutch people feed their swans bread, so I thought that was the thing to do. Then I came UK and heard the same as you, that bread was no good for the swans. Knowing that I wasn't gonna spend my personal money to buy food for the "Queens Pets" I stopped feeding the swans completely. Came back to live on the boat and boaters told me it's fine to give them bread.
Swans don't like stale bread though (picky scroungers).
When I heard the stomp and saw the body language of the swan I really felt like I was at the wrong place at the wrong time, and made sure to get away at the right time. 🤣
Yes, pick the mould off first. Trust me, I've never met a cuddly swan yet lol. Keep your distance. 🙂
Ah yes,no mould for sure. They hate even if the bread goes a bit hard. I thought of you holding the cygnet when I felt his aggression 🤣
Well I had help. Don't get any ideas. 😁
Haha! Oh no! I don't play hero; especially not with wildlife (on my own) 🤣😁
