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in research, virtually out of date the day they are published.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weeks ago mention was made that Christidis and Boles was out of date.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?
