Complex wildlife problems often require complex and labour intensive solutions. While quick and inexpensive forms of bird control may prove successful over the short-term they often fail in the long run.
- Owl Decoys – a predator lookalike used to scare other birds away. These decoys may have success initially, but birds quickly learn to ignore threats that are not real.
- Ultra Sonic Sounds– devices that emit sounds at frequencies designed to frighten or disorient birds. These products do not represent a threat because birds are incapable of hearing ultrasound (>20 kHz) (Beason 2004).
- Audio Repellants – devices that produce noises designed to repel birds by mimicking the sounds of predators. In the short term birds may respond to noise cues however, without a real threat from predators birds will ultimately ignore such sounds.
