Breeding Bird Survey (BBS)
This national monitoring scheme is administered by the BTO and jointly funded by the BTO, JNCC and RSPB. It has been running since 1994 and its primary aim is to provide population trends for common and widespread bird species in the UK.
Survey plots are randomly-selected 1-km squares of the National Grid, and the same squares are surveyed each year. Volunteers visit their squares three times each year during the breeding season, once to record simple habitat data, and twice to walk a fixed route, recording birds seen and heard. There are more than 250 BBS squares across Sussex, covering every type of habitat, and new volunteers are always needed.
Volunteers must be able to recognise common and widespread birds, but previous experience of survey work is not necessary. Help and support from experienced volunteers can be arranged if required.
The BBS squares (asterisks indicate priority squares that have been surveyed before) in Sussex which currently need volunteers for the 2025 breeding season are (updated 11/12/2024):
