Survey – WeBS






A joint scheme of the BTO, WWT, RSPB and JNCC, the Wetland Bird Survey (WeBS) is the monitoring scheme for non-breeding waterbirds in the UK which aims to provide the principal data for the conservation of their populations and wetland habitats. The data collected are used to assess the size of waterbird populations, assess trends in numbers and distribution, and identify and monitor important sites for waterbirds.

Once-monthly, synchronised counts are carried out (primarily September to March) at as many wetland sites as possible. Counts can take anything from 15 minutes to 3 hours depending on the size of the site.

Dates of the counts are pre-determined by the BTO and are set on Sundays. It is generally accepted that a count can be carried out a day or more either side of these dates if counters have other commitments and there is not an interchange of species with other neighbouring sites.

Sites requiring new volunteers are listed below (updated 16/11/2023). For further information please contact:
