The BOS has produced a monthly newsletter since January 1956. All members receive a copy of the newsletter each month. It contains the recent bird sightings and other articles of interest to members. Past newsletters are available to download for each year from the files below. The newsletters have been compiled into an annual report with an index at the beginning so you can quickly locate the newsletter for each month, except for the years 1956-1963 which are only a few pages long. Note that some December and January newsletters have pages omitted where the society's accounts have been removed. The older newsletters have been digitally scanned from the original reports, which in some cases means that the legibility is poor due to the way the originals were reproduced. In most cases it should be possible to perform textual searching within each document, allowing information on specific species to be located, for example.

  • There was no newsletter for September 1957
  • Newsletter #79 August 1962 is missing
  • There are some errors in the numbering of the newsletters, such as there being two issues numbered 605 and there being no #85
  • In the 1960s some months had supplementary newsletters with their own issue number
  • The February 2008 issue #632 says "January 2008" at the top of each page 

The newsletters have also been compiled into compendiums for each decade. This makes it easier to download the entire collection of newsletters. See this page for the compendium files: Newsletter Compendiums.
