Over the years various members of the group and local birders have reported a wide variety of colour-ringed birds in the county. As we run a long-term urban gull project, not surprisingly our most-reported species is Herring Gull, but what about other species? A quick look at the numbers from the BTO's DemOn (Demography Online) database gives us records of over 4,500 colour ring reads of 26 different species, summarised by year here:
As expected, other gull species feature right at the top, followed by species that we run RAS (Retrapping Adults for Survival) projects on: Kittiwake, Jackdaw and House Sparrow. We don't ring any smaller gulls ourselves, so all of the records of Mediterranean and Black-headed Gull resightings come from other schemes, often abroad. In fact a lot of the larger gulls are from abroad as well, with French Great Black-backed Gulls topping the table, closely followed by Belgian and French Mediterranean Gulls.

We're always keen to receive new sightings though and can help in tracing birds with the different coordinators, so if you're lucky enough to see any colour-ringed birds then drop us an email with details - westcornwallringinggroup@gmail.com
