Thanks Margaret, Martin & Julian. Worth sharing with
the ‘line, I think. Breakdown rate of Pindone seems little
comfort. A raptor could take a rabbit immediately after the rabbit had ingested
Pindone. g

Margaret alerted me to the fact that 1080 is a well known
rabbit poison. This page is useful - compares 1080 with Pindone for
rabbits.
http://www.agric.wa.gov.au/PC_93068.html?s=1001
Now that I think of it, the property adjacent to Callum Brae (Mugga?) had new
1080 warning signs some time ago, I assumed for foxes but maybe it was
for the rabbits. Above web page suggests that 1080 is less harmful to
native wildlife than Pindone. It says Pindone is "toxic to a number
of birds (eg. parrots, eagles)"

This http://www.apvma.gov.au/products/review/docs/pindone.pdf
is free and seems rather authoritative. My reading (of pages 24 et seq)
is that most cases of bird death relate to inappropriate placement of the
baits,
It also cites1080 as a bunnie bait whereas I had thought it was used for
dingoes.

It should be relatively easy to ensure that birds
don't get at the baits per se. The problem is what is the secondary
transmission rate through eating poisoned carcases. I'd suggest that
ducks, parrots, pigeons and magpies rarely eat dead or moribund rabbits but
eagles often do.

Assessment of the Potential Toxicity of an
Anticoagulant, Pindone (2-Pivalyl-1,3-Indandione), to Some Australian Birds.
GR Martin, WE Kirkpatrick, DR King, ID Robertson, PJ
Hood and JR Sutherland
Abstract
The sensitivity of a number of avian species to the
rabbit poison pindone (2-pivalyl-1,3-indandione) was investigated using
increase of prothrombin time (PT) as an index of poisoning. Daily dose levels
of pindone were 0.25 mg/kg for eagles, 4.0 mg/kg for magpies and 5.0 mg/kg for
pigeons, parrots and ducks. Considerable species variation in response was
observed, and within each species there was considerable individual variation
in response to pindone. The PTs of magpies and ducks increased to approximately
twice baseline levels. Significant elevations (4- to 7-fold) occurred in
parrots, pigeons and eagles. Clinical symptoms were observed in only one
species, the wedge-tailed eagle. Results of dosing trials indicate that all
species tested are theoretically at risk of pindone poisoning, although the
risk to some species is minimised by factors such as population size, food availability
and bait placement.

I had thought that Pindone, which was used in at
least one year, might have contributed to a failed L Eagle nest nearby, but the
available information about the product would not have supported
representations on the matter.

Jerrabomberra Wetlands
To:
Martin,
The control of rabbits in Jerrabomberra Nature
Reserve is part of Parks, Conservation and Lands annual pest species
program. At Jerrabomberra Wetlands there are two types of rabbit control
conducted, which are the use of baits and fumigation. Ripping of warrens
is not feasible in most areas due to pipe and cable lines.
Rabbit control at Jerrabomberra Wetlands results
with varying levels of success. The numbers of rabbits does reduce, each
time there is control work is done. Unfortunately we then find rabbits
come in from other areas.
The areas that have been controlled in previous
years have included reserve area running along Dairy Road past Birrigai,
including the ACTEW sewerage sites, the garden areas near the bird hides surrounding
Kelly's Swamp and above the Billabongs.
At present I do not know when the baiting and
fumigation program will be conducted, as there are a number of reserve areas
currently being treated. I do know that the warrens at the wetlands have
been recorded as rabbit distribution does vary from year to year. Signage
is always placed on public entrances to reserve areas prior to commencement of
any activity.
Thank you very much for enquiry. Have a safe
and Merry Christmas

I have heard that funds have been obtained for
rabbit control at Jerrabombera Wetlands. An excellent bit of news! Can you tell
me:
> which parts of the Wetlands are to be
covered by this work; > when it will be undertaken; and > the
strategies to be used (baiting/fumigation/shooting/ferrets and nets/ripping the
warrens.)
