There are various gull colour ringing projects in the UK and elsewhere in Europe. The schemes can be identified on the European Colour Ring web site and reported through the EURING web site.
Please complete as much information as you can on the form. If you see more than one bird at the same time you can report them all on one form, otherwise please use separate forms for different places and dates/times.
This project is operated by amateur ringers and ornithologists - we will do our best to respond to your sighting within 7 days.
