متن کاملEffectiveness of Gas Cannons on the Bird Community at Sydney Airport
Bird control takes many forms and can include the use of gas cannons to scare birds away from noncompatible land uses such as airports. Birds Australia designed and implemented this study to assess the effectiveness of the Gas Cannon as a bird deterrent at Sydney Airport. The cannons were used in two ways: statically (set up at one location) and opportunistically (transported to a particular lo...
