NARACOORTE'S noisy corellas are still being a nuisance, despite the control program in place since December.
For a short time on Monday night, the size of the problem was underlined to residents when hordes of the squawking pests filled the skies after taking flight in response to culling efforts, creating a cacophony of high-pitched noise.
Naracoorte Lucindale Council, which with the help of the SE Australian Deer Association and local duck shooters is culling 1000 of the pest birds, took a short break from shooting over Christmas but is back to business.
The aims of the program are to reduce the number of birds and drive them away from the township where they are damaging infrastrucure.
The council's director of planning, environment and community development Steve Bourne said things were looking promising before the holidays but there seemed to have been an influx of birds since then.
He said they had a tendency to congregate at three key locations - Memorial Park, Naracoorte High School and the swimming lake.
"We are shooting at them simultaneously so the birds are not just moving between the sites," he said.
"We have taken a really careful approach to shooting but we do sometimes get reports of birds who are not cleanly killed."
The council is trying to solve the problem as humanely as possible and has also had a corella trap made by a local engineer which will be implemented this month.
Animal ethics approval has been granted and the trial will be done with Department of Environment, Water and Natural Resources staff.
The prescribed shooting times are in the mornings from 6am to 7am and in the evenings from 8.30pm to 9pm. These times have been deemed the safest with the least people around while providing maximum effectiveness.
If shooting is heard outside of these set times, council advises local police be contacted.
Mr Bourne encouraged anyone to contact council with concerns and information if the corellas move to other key areas in the town.
