Corn bunting A special thank you Eleanor Bentall (rspb-images.com) to volunteers Bird monitoring in the UK is led by NGOs in collaboration with the Government, but depends on the efforts of many thousands of volunteers, without whom the evidence base upon which bird conservation in the UK relies would be sorely lacking. The state of the UK’s birds gives us the opportunity to recognise and celebrate the massive role of volunteers in bird monitoring, and to thank them for the time and effort they devote to the schemes described within the report. If this is you, then thank you; if not, why not consider joining one of the schemes outlined at the back of the report? Through simple and enjoyable birdwatching activities, you will be able to make a valuable contribution to conservation.
