Planning and preparation for BTO surveys this breeding season is going ahead as normal. Volunteers participating in any BTO survey will be expected to act within any government restrictions and guidance in place at the time.
The Breeding Bird Survey (BBS) is a national monitoring scheme 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. Population trends for Sussex are also produced and published in the Sussex Bird Report.
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 200 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 2021 breeding season (updated 25/4/2021) are:
