Authorities are investigating the suspected poisoning of 120 protected native birds, including 76 wedge-tailed eagles, after they were discovered on a property near Violet Town.

The birds were discovered after the Department of Environment, Land, Water and Planning executed a search warrant at the property earlier this week.

The three-day search resulted in the discovery of dead wedge-tailed eagles, kites, hawks, falcons and other native bird species.

It comes a month after several wedge-tailed eagles were found dead on Earlston properties, leading to widespread community concern.

DELWP acting regional manager of compliance operations Greg Chant said investigations are ongoing.

“Carcasses have been recovered from the property and will be tested to determine the exact cause of death," he said.

“The community is justifiably outraged by this incident and our investigations are continuing.

“We are now seeking information from the community to help find the people responsible by contacting Crime Stoppers. Reporting is confidential and we only need your information to help solve this crime."

All native birds are protected under the Wildlife Act 1975 and deliberately killing them carries a penalty ranging from $8261 to $39 652 and/or six to 24 months' imprisonment.
