Thanks for your question. Well I can't pass that by. The birds of Canberra are known in immense detail. Due mainly to our Garden Bird Survey that has been going continuously since July 1981. It would be great if other centres did the same. Some have done for a year or two (eg Brisbane, Tasmania, Hunter Region NSW). We have detailed information on the populations of our species continuously by month since July 1981. Most of the information is on monthly trends and long-term trends. Plus a lot of higher level information about relationship of recording rate to abundance, importance of observer variability, how long it takes to establish an accurate list of species present and breeding, etc. My report on the COG GBS should be out soon. It contains written details of population trends of about 150 species (and graphs for 120 of them) based on the first 18 years of the survey. To answer your question, we have had 218 species, of which 95 were recorded every year, the number of species recorded per year varies from 135 to 147. It also contains a literature review of other urban bird studies around the world and the role of this one. It also contains a full description of the methods and the history of the GBS and a sample of the chart. This would be enough so that anyone, anywhere could do the same. For the survey to work though, it needs at least 50 people contributing, and probably a lot more if the habitat is more variable than Canberra. (As most major, especially coastal, cities are).

Good morning all
I'm interested in the number of species found in other cities and towns
of Australia.  Has anyone an idea, for instance, of the total of species
for Sydney, or Melbourne, or Adelaide?
