The EPA is aware of the poisoning of 16 birds, including White Ibis, Brush Turkey and Wonga Pigeon, at the Reserve, which is adjacent to Ironbark Avenue, Sandy Beach.

Investigations commenced after the EPA received reports from concerned local residents in October.

Initial investigations indicate the birds were poisoned with the pesticide fenamiphos, which is illegal to possess for home use. Fenamiphos, is highly toxic for the user and any child or adult that comes into contact with dead animals or suspected baits.

EPA Director Regulatory Operations Steve Orr said it was a serious offence to use pesticides that kill or harm animals such as native birds.

"We've tested the dead birds and the results were positive for pesticide poisoning. It is concerning native species have been killed in what appears to have been a deliberate and illegal act," said Mr Orr.

"A person convicted of using a pesticide that results in the death of animals such as native birds can be fined up to $120,000.

"Residents are urged to avoid suspected baits or dead birds in the area and immediately report sightings to the EPA and any other relevant information."

Relevant information should be reported to the EPA's Environment Line on 131 555. This includes:
