Acknowledgements

We wish to thank everyone who has helped us in monitoring Bitterns in the UK: site managers, landowners, wardens, volunteers, county recorders and local birders for their reporting of boomers and in many cases following up reports of birds. Particular thanks go to the landowners and site managers who have allowed access to sites for monitoring and to all those who have monitored sites and have helped with co]ordinated watches, including volunteers and staff at a number of reserves across the country. The Bittern Monitoring Programme was funded through Action for Birds in England, a conservation partnership between Natural England and the RSPB, and organised by the Species Monitoring & Research section of the RSPB Conservation Science Department.
