Birds of the Banbury Area by T.G. Easterbrook is the third decennial (10 year) report by the BOS, covering the years 1972-1981. The report includes the full list of bird species seen in the BOS survey area up to 1981, along with a detailed listing of sightings within the report period. During this period records started to be recorded using 1km OS grid references via a record card system. This period also saw the introduction of the use of a micro-computer (PC) for information storage, something that was significantly ahead of its time and almost unheard of in the birding community.
