This is the time of the year to sign up to take part in the BTO Breeding Bird Survey (BBS) for this coming breeding season. Some squares have recently become available and there are plenty of squares available right across the county; some of these squares are accessible if you have limited mobility or if you are reliant on or choose to use public transport.

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 by sight and sound, and must be able to physically get around a survey route reasonably early in the morning, but beyond those requirements absolutely anybody is welcomed into this survey scheme. Previous experience of survey work is not necessary and help and support from experienced volunteers can be arranged if required; there are also some informal practice sessions arranged in Sussex in March and April this year. Finally there is no requirement to conduct surveys alone – take a friend with you!

The following BBS squares may be accessible to you if you have limited mobility (including using a wheelchair) as the survey routes are entirely on pavements and minor roads:
