The Garden Bird Survey (GBS) has been run by the Canberra Ornithologists Group (COG) since 3 July 1981. Summary results of the GBS are published by COG in the Annual Bird Report published as an issue of "Canberra Bird Notes" in hard copy and on the COG website http://cbn.canberrabirds.org.au/ (navigate through the link to Canberra Bird Notes). The basis of the Survey is a site equivalent in area to a circle of 100m in radius around the observer's home or workplace. Not all sites are circular but all are approximately 3Ha in area. There is no restriction on the elevation of the bird when observed, and birds flying over the site are included. Most of the Survey sites are located in the urban area of the ACT but some are also located in the City of Queanbeyan and the villages and rural residential areas in the areas of NSW surrounding the ACT. A State indicator shows which sites are inside or outside the ACT.
