An Ongoing Annual Survey
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 identify important sites for waterbirds.This survey takes place every year and, if you are not very experienced and want to start off with a straightforward survey, then the Wetland Bird Survey (WeBS) may be for you. You only have to be able to identify waterbirds (gulls and terns being optional) and sites vary from village ponds to canals to large reservoirs (and outside Surrey the coast).
You do not need to belong to the BTO in order to participate in this survey.
The Time of Year for the survey
The survey only has to be carried out between September and March although, if you can cover the site from April to August, that is even better.
What the survey involves
You go to the site and count all the adult (and young that are ¾ grown) waterbirds that you see. Counting Gulls and Terns is optional. You also record how much ice is present (if any), visibility and disturbance. Here is a link to the paper form you can complete for the WeBS survey count which shows the information you need to collect. The on-screen form is very similar (see below).
When do you do it?
On a set Sunday each month although, if you cannot carry out the survey on that day, you are asked to do it on the closest day possible). Here are the dates for 2021:
- 23rd January 2021
- 20th February 2021
- 20th March 2021
- 17th April 2021
- 15th May 2021
- 19th June 2021
- 17th July 2021
- 14th August 2021
- 11th September 2021
- 9th October 2021
- 13th November 2021
- 11th December 2021
At inland sites (i.e. Surrey) morning is normally best, when many species are most active.
More information on why this survey is being run
The network of sites legally protected for their importance to wintering waterbirds depends fundamentally on the WeBS counts. “Waterbirds” includes wildfowl (ducks, geese and swans), waders, rails, divers, grebes, cormorants and herons. Gulls and terns are optionally included. In a typical year over 220 waterbird species, races or populations are counted in WeBS, including non-native, feral and vagrant species. National trends are produced for the most numerous 110 of these.
WeBS is a partnership between the BTO, the RSPB and the Joint Nature Conservation Committee in association with the Wildfowl and Wetlands Trust (WWT).
What skills are required?
Anyone can take part, even near beginners to birdwatching. Unlike many bird surveys, to carry out WeBS Counts, you do not have to know bird songs or calls, you just have the ability to identify common waterbirds.
You can complete paper forms but you can also enter results online.
Where are the survey sites in Surrey?
For this particular survey, for historical reasons, the area is not the BTO Surrey region but instead Surrey and SW London (being the old County of Surrey). Accordingly there are tidal areas of the Thames included in the area as well as some of the large London reservoirs as well as smaller lakes in the south of the County. See this list of all the sites in Surrey and SW London. This list includes all those that are allocated and those that are vacant and need covering. Alternatively this map shows all Surrey sites and which are vacant (click on the site to see its status). Can you help with one of these sites?
Remember even counts from small water bodies are important even if the site only seems to support the more common birds such as Mallard, Moorhen and Coot.
