Ringing Trip to Mew

A CBO ringing team visited Mew Island on 14th May to ring Eider ducks. 51 birds were handled of which 23 were new birds and 28 were retraps (birds which were ringed previously, and have been recaptured to read the ring number). Of the retraps, 4 birds were ringed in 2008, 7 in 2009, and 8 in 2010. This long-term CBO project is showing encouraging retrap results which will feed back into the BTO database and provide important longevity information on the life of these marvellous Copeland birds.

The team were fortunate to visit on a beautiful spring day. On the way out, passing Lighthouse Island (home-base of CBO) 24 Puffin were spotted in the water below the sound-system/decoys.
