Evaluation of Bird Control on Landfill Sites: Case Studies

Extent of the Problem
• World-wide Issue: Waste is produced on every continent in the world. In the UK there are over 400 domestic waste landfills
• Scavenging birds are attracted to feed on waste and may represent a birdstrike hazard to airports
• In the UK, CSL is undertaking a 4 year study to determine how best to control birds on landfill sites
Experimental Protocol• Monitoring Birds on site• Determine numbers of birds on and in the area
• Implement Bird Control and test until failure or habituation occurs
• Remove control and monitor return of birds
Methods of control• Static, Unskilled or Skilled Control• Netting systems
• Pyrotechnics• Birds of Prey• Distress Calls
• Blank Firing Pistols• Bird Scaring Kites• Automated sound generators
Netting systems

Conclusions• Most techniques have some effect• Individual methods are unlikely to deter all
target birds all of the time
• CSL is now looking at the level of deterrence which can be achieved using combinations of techniques
• Effectiveness of control varies between sites but the principles are broadly applicable to sites throughout the world
