BBS annual reports (Breeding Bird Survey Reports)
The BBS started in 1994, and a report is produced every year containing population changes and other results from the scheme. It documents the changing fortunes of around 120 UK breeding bird species, based on data gathered by BBS volunteers.
Since 2016, the Breeding Bird Survey Report has also included population trends of specialist waterbird species, again based on volunteer-collected data from the BTO/JNCC/RSPB Waterways Breeding Bird Survey (WBBS).
Annual reports for every year back to 1994 are available to read and download.
The State of the UK's Birds
The State of the UK's Birds report (SUKB) draws together results from annual, periodic and one-off surveys. It aims to give an up-to-date overview of the health of bird populations in the UK and its Overseas Territories.
