Crop protection devices

Protecting horticultural and viticultural crops involves techniques that can include the use of audible, visible, or physical means to discourage or frighten birds away from crops. The birds may be frightened by something new and unusual in their environment (eg, flashing lights or strange sounds) or by something that simulates a threat (eg, a gun or predator). Another option to protect crops from bird feeding is netting. Every situation is different, and techniques that work well on one site may not work at another; and different bird species may not react in the same way to a particular control option.
