The BTO/JNCC/RSPB Breeding Bird Survey (BBS) is the main scheme for monitoring the population changes of the UK's common breeding birds. Volunteers undertake two visits each spring to a 1km square to record the birds they see and hear.
Results are produced at a national level and also for each of the government regions. BBS Results are produced annually by the BTO for the London government region and a summary of these results is included in the London Bird Report.
London trends are currently only produced for a small number of species, and by increasing the number of squares covered, we will be able to report on more species in the future. Please contact your BTO rep if you can help or would like more information about the survey:
