Newmont to fund black cockatoo health research

Murdoch University is to receive $150,000 from Newmont Boddington Gold to help fund black cockatoo health research over the next three years.

The funding will primarily be used to support a research fellow position with remaining funds contributing towards project costs.

Project leader Dr Kris Warren from Murdoch University’s Conservation Medicine Program said the money was great news for the three black cockatoo species endemic to South-West Western Australia which are experiencing declines – Carnaby’s cockatoo, Baudin’s cockatoo and Forest red-tailed black cockatoo.

“It is critically important for us to understand more about the health and demographics of our black cockatoo populations so that we can help to develop management plans to safeguard the future of these iconic species,” she said.

“The funding from Newmont will mean we can employ postgraduate veterinary researcher Dr Anna Le Souef to help us continue our work in determining the ages of wild black cockatoos. This will help us to understand their life histories and age demographics, give us an insight into their life cycles and aid species recovery programs.

“There have been concerns that the average age of flocks is increasing and many birds are past breeding age. If this is true, then there may be a population crash when the older birds die. Our research will assist in understanding the ages of wild birds and the demographics of flocks.”

Dr Warren and Dr Le Souef are collaborating with Department of Environment and Conservation (DEC), Perth Zoo, the WA Museum and researchers in North America to determine the age of the birds using a method which measures the concentration of a compound, called pentosidine, in the skin of birds.

They are using this method on samples collected from museum specimens from the Hopetoun flock that died from heat stress in 2010, and wild injured and debilitated black cockatoos admitted for treatment to the Perth Zoo Veterinary Department.

Dr Warren has also been collaborating since last year with colleagues from DEC, Perth Zoo and Birdlife Australia to determine whether disease is a threatening factor for black cockatoos.

She and Dr Le Souef worked closely with DEC during routine nest checks in the last two years to obtain blood and swab samples from black cockatoos for health assessments.

“This kind of health data on wild black cockatoos is virtually non-existent due to the difficulty in obtaining samples,” she said. “Working with DEC, we were able to obtain blood and swab samples from wild nestlings.

“The money from Newmont will ensure we can continue to collect these samples so that we can get as clear a picture as possible on the overall health of black cockatoos.

“The major threats to black cockatoos are well-known. These include habitat loss, competition with other species for nesting hollows, climate change and human impacts such as vehicle strikes, illegal shooting and poaching. We need to work quickly, collaboratively and comprehensively with our partners to find out if disease is another contributing factor.”
