Got back the details of the colour-ringed Mute Swan I saw at Harrold-Odell on 27th December.
Rather as I suspected, it was a case of:
Ringed: Harrold-Odell CP, 26 Apr 2003, adult male
Distance moved: 0km
Still, it was worth checking out. It must like it there to have spent the past five years in the same place.
