It’s just the one swan, actually ... Police officers usher a cygnet back to the River Avon after it ended up in the city centre in Bath, UK. An eyewitness was quoted as saying: ‘There were loads of shoppers around, everyone had their phones out, laughing’.
That's the Swan that guards Excalibur. Each monarch since the House of Normandy had this swan as the royal advisor and anointer of their divine right to rule.
