THE Department of Environment and Conservation has widened its investigation into the death of seven corellas at a Greenwood Park to other sites.
A spokeswoman said similar deaths in several other northern suburbs had prompted the DEC to widen its testing for the cause.
“We are looking at other links to corella deaths in surrounding areas. The birds are of the same species. Testing could take a month.”
Greenwood residents suspected poisoning when they found the dead birds in one area of Blackall Park early on June 30.
Residents have also reported bird deaths at Carine Open Space and at Carine Glades Shopping Centre.
