BTO Breeding Bird Survey: new squares available

Now is the ideal time to sign up to take part in the BTO Breeding Bird Survey (BBS) for this breeding season and to arrange to come along to an informal practice session with other volunteers. Some squares have recently become available and there are plenty of squares available right across the county.

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. 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, and some informal group practice sessions are planned for late March 2022, to which new volunteers will be invited.
