Mediterranean Gull colour-ring codes

INSTRUCTIONS: to report a colour-ringed Mediterranean Gull please choose from the examples below, and click on the image that best fits your observation. The link will then take you to the relevant contact details of the project recorder/co-ordinator(s).

In some instances similar codes have been used by different projects within and between countries. In such cases the image will link to further information to help you locate the correct contact details.

In the next 5 to 10 years, Mediterranean Gulls wearing the old-style colour-rings with 3-character alphanumerical codes will still be observed in the field. For more information about the new 4-character alphanumerical codes and a list of the national programme co-ordinators click here
