The British Ornithologists' Club objectives are to advance education in the subject of ornithology for the benefit of the public by promoting scientific discussion between members and others interested in ornithology and to facilitate the dissemination of scientific information concerned with ornithology, and in particular avian systematics, taxonomy and distribution.
The BOC produces a Bulletin four times a year. Up to the end of 2016 hard copies have been sent to all members. However, from 2017 the Bulletin has become an open access online-only publication. The contents of the most recent Bulletin, as well as earlier issues, can be viewed here.
The Club is a Charitable Incorporated Organisation. From 2017 the BOC has ceased having a membership fee.
