The BOS has published annual reports since 1966. Each report summarises the activities of the society over the year and a review of the bird sightings.

A status update is provided for each of the reserves the society owns and manages. A detailed report on the ringing undertaken is provided along with results. Fieldwork activities, including a our summer and winter surveys, is summarised. A major part of the report is the Systematic List, which is an annual review of the sightings and status for each of the bird species on the list.

Each member of the BOS is supplied a printed copy of the Annual Report as part of their membership fee. Copies of the report are distributed to the county bird clubs and national ornithological organisations.

Digital copies of older reports are available for reading from the list presented below. Note that the reports from 1989-2002 have the membership list omitted since those reports also included the addresses of members.

Content may be reproduced in part as long as it is suitably credited to the society and, where relevant, the author of the material.

A combined list of contents has been compiled to make it easier to locate specific material: Contents of BOS Annual Reports.
