solanum with native miner, a pest species

The native noisy miner is causing more damage than the invasive, introduced species of myna bird, new research has shown.

The research paper, to be published next year, assessed the impact of the native species on other native birds.

It found the noisy miner was taking over the declining woodlands from smaller birds, causing steep declines.

The birds have become such a big problem they have been nominated as a threat under the national environment protection act.

One researcher recommended a trial cull of the aggressive animal.

Dr Martine Maron from the University of Queensland said scores of different species were being impacted.

"We're quite worried about the flow-on effects of that for ecosystems, because without those small woodland birds, then there's the risk that tree and woodland health could decline," Dr Maron said.
