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. These pages contain information on how to get involved in the survey, the methodology, and how to access data and publications and results. If you have any problems, please contact us.

Bar-tailed Godwit

Next WeBS Core Count date: 17 June 2018

By June, the breeding season is in full swing with many birds on nests or even with young, but please remember not to count these young birds on your monthly counts until they are 2/3 grown. Some coastal sites may still see large congregations of non-breeding waders such as Bar-tailed Godwits or Sanderling that have remained in this country. Although generally a quiet month for rarities around waterbodies, occasional vagrants such as Squacco Herons, Caspian Terns and Collared Pratincoles may turn up. Stay safe and enjoy your WeBS Count!
