SOS is the county’s main bird club. It has over 2,000 members and was founded in 1962 to promote the recording, study, conservation and enjoyment of birds in Sussex. We encourage members and others in Sussex to keep and submit records of the birds they see and to take part in survey work to monitor bird populations. Our database now has over seven million records, which are regularly used to support bird conservation (for example in evidencing why a site that is threatened with development, is important for key species).
