Finally, after 24 years of ringing Whooper Swans with Yellow darvic rings (both in Iceland & the UK) we used the last yellow ring & this year started to use Red darvic rings.
This wee guy was the first to have a Red darvic ring fitted!
The things we’ll do to ring birds! Well OK we did really want to get half naked and run around a lake catching swans! We didn’t need much persuading!
