I met Dave Edwards over at Doffcocker Lodge in Bolton after work today, to start our 2011 colour ringing on the Common Terns there. Dave’s study on juvenile dispersal is now into it’s 6th year and today we added a further 15 colour ringed chicks, with one chick being too small to hold colour rings, so was BTO ringed only.
2011’s chicks are given a yellow colour ring above the BTO ring on the right leg, along with a grey colour ring on the left leg. Yellow is the site colour = Doffcocker and the Grey ring is the year colour = 2011.
Any sightings of colour ringed Common Terns can be sent to www.ring.ac
