The Clwyd Bird Recording Group was founded by Peter Rathbone in 1989 with the main aims to collect bird records and publish a bird report. The recording area was initially the county of Clwyd, but then after local government reorganisation and the end of Clwyd, changed to vice-counties 50 Denbighshire and 51 Flintshire. The group is very grateful for Cofnod hosting a collection of all the known bird reports that have been published.
