Night Parrot - Pic by John Young |
A second critically endangered night parrot disappeared after its mate vanished when it was caught and fitted with a radio transmitter by a team of experts charged with saving the birds from extinction.
The revelation
prompted calls for the federal government to sack the night parrot
recovery team and appoint a senior public servant to oversee the
conservation program.
The night parrot is
one of the rarest birds in the world. It had scarcely been reported
for more than a century before naturalist John Young photographed one
in western Queensland in 2013.
A pair of night
parrots were discovered in the East Murchison area of Western
Australia in March 2017. The Weekend Australian reported two weeks ago that recovery team chief Allan Burbidge led an expedition to the site
five months later. The team caught one of the parrots in a net and
fitted it with a transmitter, but no trace of the bird was found
subsequently.
Recovery team
sources said for the next three nights, a second parrot called
frequently at the site during the night as it tried to find its
missing mate. The second bird then evidently vanished.
Dr Burbidge says the
transmitter failed, and there is no evidence the bird fled the area
because it was traumatised, or fell victim to a predator because it
was injured or encumbered by the device.
But one of Dr
Burbidge's team, Tasmanian zoologist Mark Holdsworth, said it was
possible the parrot perished. “That couldn't be
ruled out,” he said.
Dr Burbidge agreed a
second parrot was calling at the site when the bird was caught. “Steps were taken to specifically avoid flushing or catching this
bird,” he said. “The signal from the transmitter was lost on the first night but...
one bird was roosting at the capture site for at least two nights
after the capture. It later appeared to roost elsewhere.”
Zoologists Mark Carter and Chris Watson recorded the calls of what
was believed to be a night parrot in the Northern Territory in
January 2017. Night parrot recovery team guidelines warn birds should not be
flushed from daytime roosts: “Doing so will expose them to diurnal
predators and potential heat stress.”
But Mr Carter said
the team urged him to flush birds to photograph them. He was told
this was standard practice on Pullen Pullen, the Queensland reserve
where Mr Young photographed his birds.
Referring to the WA
capture, Mr Carter said: “Now we learn... the “experts”
undertook extremely risky interventions.” Mr Carter said the team should be replaced
by a senior statutory officer.
End of story.
What follows are expanded comments from Mark Carter, a well-regarded Alice Springs birding guide.
Commenting on an approach by the recovery team about the NT bird: "The idea was that I would flush the bird in
daylight to get photographs to ‘confirm’ the presence of the species. I
was assured that this was a common occurrence at Pullen Pullen and
that it did no harm to the birds. They also made this request to the
NT Government. I was against taking any such action as I felt the
risk of flushed birds being injured or killed by predators or of
disturbing any nests was too high just to further confirm what we
already knew from sound recordings and observers hearing the birds
call at the site."
Elaborating on the possible fate of the two WA birds: “Now we learn that in one case at least ’the experts’ have
been undertaking extremely risky interventions which are not
justified by the possible outcomes. Currently we know of very few
sites for this species and each individual bird has to be considered
to be extremely valuable and precious. We know very little about
their capacity to tolerate disturbance but the early indications are
not promising- deliberate disturbance to the birds has huge potential
to do harm."
One of Burbidge's expedition members, Mark Holdsworth, Tasmanian zoologist of orange-bellied parrot fame, begs to differ. Holdsworth took to Twitter to dismiss my first report as "bullshit". When I asked him to indicate errors in the story, Holdsworth responded by blocking me. I thought this was ironic given it was Holdsworth who had confirmed to me rumours about the capture before the story was published. Moreover, as indicated above, Holdsworth agreed it is not possible to say that the captured night parrot is dead or alive. "We have no way of knowing what happened to that bird,” he said.
It's worth noting that most of the 15 people on the night parrot recovery team were not aware of the plan to capture and tag a bird in WA. Asked if there was any obligation on him to consult the whole team, Burbidge told me: "Tracking of night parrots was identified as an action in the Night Parrot Research Plan. Since 2014, there have been discussions in the recovery team regarding potential tracking projects."
Burbidge says the netting and capture was approved by the Animal Ethics Committee of the WA Department of Biodiversity, Conservation and Attractions.
