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.

Next WeBS Core Count date: 15 July 2018

July is a quiet month on most inland waterbodies, with many birds on nests or with fledged young, but please remember not to count these young birds on your monthly counts until they are 2/3 grown. Wetland sites will begin to see the start of the return wader passage depending on water levels with Green Sandpipers being one of the first species to appear. Although generally a quiet month for rarities around waterbodies, occasional vagrants such as Lesser Scaup, Collared Pratincole or Marsh Sandpiper or maybe even a real rarity such as a Red-necked Stint may turn up. Stay safe and enjoy your WeBS Count!
