Onkaparinga Council will review its corella management program next Tuesday. Picture: Cathy Mundy SHOOTING corellas in the southern suburbs might be extended to six months a year after a report found last summer's four-month cull had little impact.
The report, tabled at an Onkaparinga Council meeting this week, found the program aimed at reducing the number of corellas in Old Noarlunga to 500 had failed.
Up to 5000 continue to flock to the area at a time, the report said.
It recommended the culling program, which involved shooting up to 200 of the birds and using noise to scare the rest away between December and March last summer, start as early as October and continue through to March 2013.
It also suggested the area's waste management program be extended to cope with the increasing bird faeces and debris, which would cost ratepayers an extra $340,000 a year.
Residents have long complained about the noisy birds keeping them awake at night, killing trees, swooping, ripping up ovals and littering the area with faeces.
The council used a shooting program for the first time this year in a bid to free the historic township of the birds.
It followed years of failed attempts using non-lethal methods such as torches, vehicle-mounted lights and starter pistols.
The council will discuss the report and vote on its recommendations at a special meeting on Tuesday, June 26.
