In 2016 the group began engraved colour ringing of Black-headed Gull and Common Tern chicks at Marsh Lane Nature Reserve, Meriden.
The darvic rings are very lightweight and enable anyone with suitable optical equipment to read the ring number and report their sighting without the bird having to be recaught to read the BTO metal ring instead.
As the project develops we will discover where birds from the reserve disperse to, how quickly and how long they survive. Check out the current sightings we've had using the link below.
Throughout Europe there are many colour ringing projects on many different species. Many of them have shared details of the project and who to contact on the European Colour Ring Birding website. Alternatively you can report a sighting of any colour ringed bird of any species to the EURING website.

In addition to the gull chicks, the reserve is also home to several pairs of Common Tern. In 2016 a total of 19 chicks were ringed with 7 also given a colour darvic ring. All our darvics on Common Terns start with C0.
