John and
all,
It was
probably a comment I made about Christidis and Boles (C&B) some time back
that John Layton is referring to. I was not denigrating C&B, rather I was
pointing out that taxonomic lists such as C&B, the CSIRO book that I
co-authored and other such lists that are, given the constant and ever changing
advances in research, virtually out of date the day they are published. The
original C&B was published in 1994 and not revised until 2008. When it will
be revised again is anyone’s guess. The same happened with the two
editions of the CSIRO list that I was involved with. In the meantime advances
in DNA etc have led to splitting, and lumping, of species. Unless you are
following the scientific journals, and this could be from anywhere in the
world, you will not know what is happening in the bird world.
The one
list that I am aware of that does try and keep up to date with WORLD taxonomy
is that put out by the IOC titled “Birds of the World: Recommended
English Names” – if you want a copy, it is downloadable as an Excel
spreadsheet. All you need to do is Google it and select what you want. It is
usually updated about 3 or 4 times a year. Currently they are up to version 2.5
(July 2010) and are working on a draft of version 2.6. In each version they
list what is currently being considered for inclusion and what potentially will
be deleted, among other things. This is the list I personally use for my list
keeping, including for Australia. It has some species that are not recognised
in C&B but that is taxonomy at work. Taxonomists will never agree on all
species. There is a book version available that as far as I am aware records
subspecies, something that I did with the CSIRO list for Australia and its
territories, but C&B does not include. It is often these subspecies that
are elevated to full specific status and if you know that you have seen them,
can give you an “armchair“ tick.
I know
from a birding friend in Sweden that the majority of Swedes use the Clements
checklist of world birds; it also includes subspecies names in its book form.
This again is different to the IOC list. I am sure there are other lists out
there that people use.
What it
all boils down to is personal choice – use whatever you think suits your
needs.

Several
weeks ago mention was made that Christidis and Boles was out of date. Not
surprising, But what is the informed birder-around-town referring to now that C
& B is yesterday’s news?
