Yesterday, I reported on a colour-ringed Mute Swan I saw at Watermead Park in Aylesbury
Today, its ringer Mike Reed, sent me some intriguing information
The bird was ringed as an adult in Apsley, Hemel Hempstead, on 5 May of this year, 206 days ago, and had moved 26 kilometres from there. It was accompanying two youngsters, so had presumably nested there or in Aylesbury. Interesting stuff
