Herts Bird Club - WeBS 2021

The Wetland Bird Survey (WeBS) is organised nationally by the British Trust for Ornithology and supported by the WWT, RSPB and JNCC. Its principle aims are to identify population sizes, determine trends in numbers and distribution and to identify important sites for waterbirds across the UK.

In 2021 the Hertfordshire counts were organised by Cath Patrick (Lee Valley from Ware south) and Jim Terry (all other sites) and were undertaken by dedicated observers each month. Some sites are not surveyed during the summer months (April to August) but otherwise coverage is most comprehensive.

In 2021 the core count were the following Sundays: 17 Jan, 14 Feb, 14 Mar, 11 Apr, 23 May, 13 Jun, 25 Jul, 22 Aug, 12 Sep, 10 Oct, 7 Nov, 19 Dec. The scheme organisers have agreed that the Lee Valley counts can be undertaken the previous Saturday, and some counts were carried out on the previous or subsequent weekends.

Sincere thanks are due to everyone who contributes to this important monitoring project and especially to Cath and Jim for their co-ordination.

We are always looking for volunteers to assist with this national monitoring effort both to fill any gaps in the existing coverage but also to take on other sites which could hold significant numbers of waterfowl. The effort involves counting all such species at one wetland site each month on Saturday or Sunday. This should ideally happen every month but most importantly from January to March and September to December inclusive. Please contact Jim Terry (46, Manor Way, Borehamwood, Herts, WD6 1QY) or Cath Patrick (c/o LVRP, Myddleton House, Bull's Cross, Enfield, EN2, 9HG) if you are able to help. Thank you.
