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 and early April 2025, to which new volunteers will be invited.
Some highlighted available squares are:
SU8718 near Cocking: this square has been surveyed in most years since 1997 and information is available from the outgoing volunteer about obtaining access permission from landowners; there is the additional bonus in this square of a regular red-tailed hawk!
SU9520 near Tillington: this square has been newly added and a non-standard route has been devised that is entirely on public rights of way.
TQ0111 Houghton: this square has been surveyed in most years since 2010 and the route is entirely on public rights of way.
TQ1904 Widewater Lagoon: this square was surveyed during 2005-2015 and due to some access problems the survey route has now been changed and includes a section beside the lagoon.
TQ3916 near South Chailey: this square was surveyed during 1995-2016 and due to some access problems the survey route has now been changed and is entirely on public rights of way.
TQ4233 Broadstone Warren: this is one of very few BBS squares in Sussex with regular redstarts; information is available from the outgoing volunteer about obtaining access permission from landowners.
TQ5023 Buxted: this square was surveyed in every year between 2005 and 2022 and the route is entirely on minor roads and tracks; there is the added advantage of a train station nearby.
