Wetland Bird Survey Annual Report

Waterbirds in the UK

The Wetland Bird Survey (WeBS) is the principal scheme for monitoring the UK’s wintering waterbird populations, providing an important indicator of their status and the health of wetlands.

Survey results are reported in the annual publication Waterbirds in the UK, which comprises a summary report and updated species and sites data and Low Tide maps via the WeBS Report Online interface.

Summary Report

All WeBS annual reports are available for download. The current format, of dual publication of a summary report together with sites and species data online, began with Waterbirds in the UK 2011/12. An extended principal sites table listing all sites with over 10,000 birds is also available.
