Taking part

GBFS counts of Greenfinch have recently declined

Only a relatively small number of people participate in the GBFS each winter. Gardens are chosen carefully from existing members of the Garden BirdWatch survey, ensuring good coverage across the UK and a roughly even split between rural and suburban gardens.

Participants often stay with the GBFS for a number of winters (some have even spanned the past four decades!) but occasionally, people drop out. As and when vacancies become available, participants from the larger Garden BirdWatch survey are approached to take their place. Thanks to the dedicated observations of GBFS participants, over 40 years of data have now been collected.
