Denise,
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?
Thanks
Denise
