Rising concerns about Little Corella flocks causing damage across the region has prompted Alexandrina Council to trial a new management tool in Strathalbyn.

The ‘flock reflectors’ use movement and light to help deter birds from settling in specific locations.

Over summer they have been installed in Strathalbyn as part of a seasonal trial and will be monitored over time.

The council says its Field Services Team works proactively to reduce damage and nuisance while balancing responsible wildlife management.

“Council officers are currently observing three separate flocks in Goolwa, including a ‘super flock’ estimated at approximately 15,000 birds. 

“In Strathalbyn, a flock of around 12,000 birds is present, with several smaller flocks across other townships.

“Birds are also being recorded in areas where they have not typically congregated in previous years. 

“The scale of turf damage, tree impact and public space disruption this season is greater than our teams have experienced in recent years.”

Some in the community have questioned the effectiveness of the flock reflectors, commenting on social media that the birds have been seen playing on them.

The council says Corella management requires a combination of strategies, which may include drone dispersal, laser and revolving lights, and other deterrents. 

“No single method provides a complete solution, so Council uses a coordinated and responsive approach to minimise impacts across our townships.”

“Council will continue to work with the Department for Environment and Water on other methods of localised abundant species management through the recently introduced Biodiversity Act 2025.

“Council continues to advocate to the State Government for a coordinated, state-wide management plan to address the broader impacts of Little Corellas.”
