That sort of analysis is sort of useful. Such a
list would be really useful if every site and suburb had been equally surveyed
by equally competent and dedicated observers over every year of the survey (GBS)
but that is FAR from the real situation. The issue is that, like most GBS
information, it needs to be taken within a context. That is why I have provided
a context. The Appendix 5 of my GBS Report lists the number of sites and charts
completed for the GBS for each suburb and has the suburbs sorted
geographically. Also Appendix 3 of my GBS Report lists the statistics from each
site (and gives the name of the suburb for each site). This is of course for the
first 21 years but the same principle applies regardless of the number of years
considered. There is a need to not take bits of these data in isolation.
p.s. Gleneagles is included in Appendices 3 &
5. I'd suggest it is really part of Kambah (on the Kambah Pool Road) but
sufficiently separate in habitat and distance to warrant its own category. It is
no surprise that being so close to suitable habitat on the Murrumbidgee Corridor
that they are a frequent attendee on the GBS list from there.
p.p.s. Martin says "In total they have appeared on 176 sheets"
and no doubt that is true but does not say out of many charts there have been
included in the 25 years of GBS. So to continue the context, 23 of these
records must have been in the last four years, in that there were 153 records
from the 1316 charts in the first 21 years, being that which has been compiled,
analysed and published. (A record being a bird at a site on a
year.)
