The reading and reporting of colour ringed birds can be an exciting part of everyone's birding. Wondering where the bird was ringed, where it was seen previously and where will it be seen next.
If you see a colour ringed bird, please report it to this link as all this information is collated and helps us to understand their movement and longevity. http://blx1.bto.org/euring/main/

Many of our Gull sightings are from birds that have either been ringed at Felixstowe in Suffolk or by the North Thames Gull Group at Pitsea or Rainham waste disposal sites in Essex but check out these pages as we have had some interesting sightings from overseas.
