On the way to a gig in Bedford, we spent a few minutes watching the Mute Swans on the river. Loads of them are ringed with a metal BTO ring on one leg, and a coloured plastic ring - with big numbers - on the other.
In about 10 minutes we notched up 13 resightings. I don't suppose any of them have been very far, but it's all useful.
