Ringed

I'm constantly surprised at the number of ringed birds which appear in photos on iSpot. Anyone care to hazard a guess at the percentage of UK birds that are ringed?

Hmm. Good Question.

I would imagine we need the opinion of someone who regularly rings birds. They'd have records of how many birds they catch that are ringed, I should have thought.

Unringed!

Perhaps I put the question the wrong way round! The BTO, I'm sure, would be able to tell us how many birds are ringed each year ... but how many are NOT ringed?
