The
report does correctly mention more than 30 years of the GBS but I don't see how
it references that information. It does not appear to quote any prior
references, notably not The GBS Report, which is just the first 21 years and
stops its time relevance at the year this ANU survey started. So I don't know
what it is quoting. I would not take much notice of GBS abundance changes for
ducks. Those data are very influenced by changes in locations of observers over
the years. Whereas I think the sites for this ANU survey have been fairly stable
and include a lot of duck suitable habitat. If you reference The GBS Report the
Myna was increasing in the GBS but according to recent ABR the word is, is no
longer correct.
It
highlights the value of an update to The GBS Report, noting the huge number of
people who have asked over the years when will I issue an update and that the
3rd edition is now (I am sort of proud to say) sold out (or I have only one left
and that is reserved for a student in Melbourne) and I will probably need to
soon retrieve some from my agent in Europe.
It
mentions the type of people that contribute to the GBS but forgot to notice that
many of the same people have also assisted this ANU Campus Bird Monitoring.
There is a
typo (I presume) in the below "Greygone".

The
comparison with COG GBS data is worth a comment. The period for the
comparison is presumably 2002-2012. I am surprised the PB Duck and Wood
Duck respectively have the 3rd and 4th greatest GBS
increase for that period. I am surprised the myna has the
5th greatest increase given a reported decline in more recent years
