Given the recent resightings of an Anglesey-ringed bird at Lock’s Common, Porthcawl, and of Gower-ringed birds at Southerndown, an article giving information on what to report and who to report is to is here: http://gowerbirdringinggroup.blogspot.co.uk/2016/11/colour-ringing-choughs-in-wales-how-and.html
The article has been written based on information supplied by (and in liaison with) Adrienne Stratford to whom the information should be sent. Adrienne will supply you with a life history of the bird concerned wherever possible.
