The Wetland Bird Survey (WeBS)


Welcome to the WeBS homepage. The Wetland Bird Survey (WeBS) is the scheme which monitors non-breeding waterbirds in the UK. The principal aims of WeBS are to identify population sizes, determine trends in numbers and distribution and to identify important sites for waterbirds.  If you have any problems, please contact us.

Next WeBS Core Count date: 20th April 2014

Spring migration is in full swing!  Movements of wildfowl and waders involving species such as Dark-bellied Brent Geese will be occurring on the south coast as birds begin travelling back to Siberia. Many will pause at UK estuaries en route to stopping over at The Wadden Sea in The Netherlands. Inland, if you get lucky, your WeBS Count could score a passage Garganey, Little Gull or Green Sandpiper, or maybe you count gravel-pits to where Little Ringed Plovers have returned? Enjoy your April WeBS Count!


Sierra Leone

January 2014 saw a coordinated effort as part of the International Waterbird Census to count waterbirds at major wetlands along the length of the East Atlantic flyway that usually receive no coverage. This included expeditions to west Africa where waterbirds tend to be particularly poorly monitored. Important sites on the coast of Sierra Leone were counted by a small team of volunteers from the UK and colleagues at the Conservation Society of Sierra Leone (CSSL). Support for this expedition was provided by the Wadden Sea Flyway Initiative and WeBS. As well as collecting important information on numbers of birds at sites in Sierra Leone, the two-week trip included training of CSSL staff in waterbird monitoring methods and engagement with local communities. A full report will be published in due course.
