Colour-ringing of four of the Gower chough chicks at two locations in 2015 was undertaken by members of the Cardiff Bay Ringing Group. Following liaison with local ringers (members of the Gower RG) and bird watchers / naturalists to determine breeding locations, permission to ring choughs on the Gower coast was sought and received from the land owner, the National Trust. Nests were then visited, under license, by Mike Shewring (an experienced climber) and James Vafidis (‘A’ ringer and ringing trainer).
This post provides the details of the ring combinations used, and has been written in order to publicise and maximise the potential for obtaining re-sighting data concerning these birds. Any data returned will provide the detailed information on both population structure and habitat use of the Gower birds that can potentially be used to inform future habitat management.
The details of the colour ring combinations used in 2015 (and some biometric measurements at the time of ringing) are provided below

As with all collaborative projects a lot of people made this possible and as such I would like to thank Gower Ringing Group, Tony Cross, Paddy Jenks, Bob Haycock, Gwen Potter, Gareth Watkins, James Vafidis, Owain Gabb, Barry Stewart and Richard Facey for their help and support. Already looking forward to next year!
If you see a chough on Gower please check out its legs and report any colour ring combinations to myself (firstname.lastname@example.org) and on the BTO website (http://ow.ly/P9E9f).
