This national survey is ongoing. Survey website
If you are interested in wildfowl, this one is for you. Organised nationally by the BTO, in conjunction with the Wildfowl and Wetlands Trust, RSPB and JNCC, Herts birders have been participating for many years building up a clear picture of population changes over time. Wildfowl are counted at the major wetland sites once a month throughout the year.
Hertfordshire WeBS results are now published in full on our website, for the years 2015, 2014, 2013, 2012, 2011, 2010 & 2009. Results for previous years were published in the Herts Bird Report each year.
Check the WeBS website for more information. We are looking for more volunteers to help with the surveys, particularly at Tring Reservoirs, and contact Cath Patrick (Lee Valley sites) or Jim Terry if you would like to take part.
