Larus canus – GWYLAN Y GWEUNYDD – Winter visitor
The common gull has never been common in Pembrokeshire, and is usually seen only in winter. Breeding populations have declined in many areas, stimulating a need to find out more about the gulls and their movements. To this end, gulls have been ringed in several countries in Europe, using a combination of colours and letters that can be read through a telescope or camera lens without the need to recapture the birds.
If you come across a bird with colour rings, please report it to European Colour-ring Birding from where you will get information about ‘your’ bird, as well as adding to the database of useful information about the species.
Please don’t just assume that someone else has reported a sighting – your record could add information such as longevity, the amount of time a bird spends in a particular place, etc.
This map is based on observations made by Sam Baxter and others at the Nevern Estuary (red pin). Blue pins show where gulls were ringed.
