    Cockatoos embrace new artificial hollows

    • Better design results in successful breeding season for Carnaby's cockatoo
    • Volunteers helped install 30 bigger hollows for the black cockatoos

    Rare Carnaby's cockatoos have taken a shine to new, bigger artificial hollows in a breeding area at Coomallo Creek, 190 kilometres north of Perth, helping to build up their numbers in the wild.

     

    Environment Minister Albert Jacob said the improved design had increased demand for the hollows among the local cockatoo population, with all of the new hollows being occupied this breeding season.

     

    "The population of Carnaby's cockatoo has been declining so every effort the Liberal National Government can make to provide more breeding habitat is going to benefit this important species," Mr Jacob said.

     

    "It is encouraging that simple changes to the design of the artificial hollows has made such a big difference for these birds."

     

    The 30 bigger hollows were installed in wandoo trees on private land at Coomallo Creek in June 2014 to provide the birds with better accessibility, comfort and protection from predators.

     

    The artificial hollows are made from large PVC pipes with smooth internal surfaces and a strip of steel mesh inside to enable the birds to climb in and out.

     

    Of the 97 natural hollows and 60 artificial hollows that have been available since 2009, the black cockatoos chose to nest in the new hollows first.

     

    Department of Parks and Wildlife officers installed the new hollows in strategic locations at the site with the help of volunteers from Rockingham's Rotary Club of Palm Beach.

     

    The Minister said that since the project started in 2009, the number of eggs laid by Carnaby's cockatoos at Coomallo Creek had more than doubled from 41 to 101.

     

    "This is a positive step forward.  Knowledge and information gained about the distribution and breeding patterns of Carnaby's cockatoos through this initiative will help guide conservation priorities and future recovery plans for the species," he said.
