Thanks Martin. I should just add that that article was written for
Gang-gang in 2001, so a couple of elements of it are a bit dated. The
more recent Whimsy appeared in Gang-gang of February 2009, but probably
doesn't add much.

G'day Peter and others
First of all, a small apology for sending my earlier message to the
entire list rather than, as my brain intended but my flying fingers
forgot, just to the editors of Gang-gang.
As I said in the element about S(T)Ds the issues raised by the invasive
nature of this species are covered in a recent Whimsy and a previous
article by Ian Fraser in Gang-gang. Rather than try to paraphrase
Ian's articles - about which I agree with Geoffrey's words below - I
have attached the earlier article for people's ease of reference (the
Whimsy is easily accessible from the COG Website).

This
morning i noticed that the 5 mallard hybrids that haunt the
carillon area had moved upstream and crossed a busy road and were
rooting
around at the base of the traffic lights at one of the busiest
intersections in
Canberra.
Re the
SD, Ian Fraser’s frequent postings on the dangers
of this species have been a model of environmental advocacy, becoming
more
sharply honed with each airing.
Thank
you for extracting the info on Spotted Doves.
I
think I missed most of the discussion on the species. What kind of
problems do Spotted Doves pose to the environment, other species and
the
economy i e possible spread of poultry diseases by visiting poultry
yards
etc? Should we be concerned about their increase?
The
writing was on the wall with Indian Mynas (i e what a pest they were in
areas
where they were abundant) when they were first noted in Manuka but
neither the
local government nor COG were concerned about them. If they were
they didn't do anything about them.
When
I started working in the Wildlife Research unit ca 1984 one of my first
tasks
was to remove feral ducks (mallards and it's various colour forms) and
geese from the local lakes at the instigation of COG because they were
concerned that Mallards would hybridise with the Black Ducks and the
geese
may go feral. Their removal was quite successfull. In NZ there are
hardly
any pure Black Ducks left due to hybridisation with the introduced
Mallards and
feral geese are abundant.
If
it turns out that there is good evidence that Spotted Doves are a
threat to
native species and/or the economy then in my humble opinion, COG should
make it known to the local government and persue the matter .
