This national survey is ongoing.

A new survey is being launched this winter which aims to evaluate how food resources in winter affect birds in lowland farmland, organised in partnership with Natural England and Defra. The structure and methodology of the survey closely follows that of the Breeding Bird Survey (BBS) and is to be conducted in the same squares. The survey differs from the BBS in that it includes Brown Hare as well as birds and requires habitat details to be recorded on each visit. A maximum of four visits are required, one per month, from December 2018 – March 2019. It is possible to do just two visits which should be between January and March. Although the main focus of the survey is lowland farmland in England, the BTO welcome volunteers to take up squares that contain all other habitats.

Full details of the survey including links to survey instructions, recording forms etc. can be found on the BTO website at English Winter Bird Survey.

Please note that although it is required that results are entered online, through BBS-online, the data entry system will not be available until after mid February. Participants should keep their field recording sheets safe until the online data entry becomes active.

For Herts this survey will be administered by the BTO Regional Representative Martin Ketcher ( on behalf of the EWBS organisers: David Norfolk and Greg Conway (
