The Wetland Bird Survey (WeBS)


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

International Golden Plover survey: 11-12 October 2014

On 11-12 October 2014 (WeBS Count weekend) there will be a coordinated census of Eurasian Golden Plovers across Europe, repeating comparable surveys carried out in 2008 and 2003.  The majority of Golden Plovers are concentrated in northwest Europe in October making it the best time to assess the status of the population. As in 2008, the BTO will be collating all counts of Golden Plover within the framework of an International Wader Study Group project.

For the UK, Golden Plover numbers provided through standard WeBS Core Counts will represent the key source of data in combination with records provided through BirdTrack. So, if you use BirdTrack, remember to submit any counts of Golden Plover on 11-12 October away from your normal WeBS sites!  Counts of Lapwings are welcomed too.


This month's WeBS Core Count date: 10 August 2014

Autumn passage at UK wetlands is in full swing. On major estuaries, non-breeding waders will be joined by returning Arctic-breeding adults as well as small numbers of early juveniles. Numbers of Sanderlings and Knots from Greenland, and Bar-tailed Godwits and Grey Plovers from Siberia, will all be starting to build up at the traditional estuarine roosts. The odd rarity will inevitably feature as autumn wader passage continues. Following July's prediction of the UK's 4th ever Great Knot being realised, this month we plump for another outrageous Siberian vagrant to grace a WeBS Count ... Sharp-tailed Sandpiper!  At many inland wetlands, waterfowl will be build in numbers too. August is typically the month when peak numbers of Tufted Ducks are recorded across the UK, and late summer also remains a good period to get accurate counts of your local Canada, Greylag and Egyptian Goose populations. Enjoy your August WeBS Count!


WeBS helps in 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.
