Abstract: Playing back bird calls is an effective and noninvasive way to drive pest birds away from farms and orchards, and widely used in agriculture and fruit industry. However, little attention has been paid to assess the bird-driving effect of playing back bird calls and the bird response behaviors. In order to evaluate the effect of playing back bird calls on driving orchard pest birds, three bird-driving modes with playing back Accipiter gentilis calls, Pica pica scared calls, and Cyanopica cyana scared calls were set up in two cherry orchards in Haidian District of Beijing in May 2009, and an indoor experiment was conducted from April to May, 2010 to examine the behavioral responses of the individuals of two main pest birds P. pica and C. cyana. The playback of A. gentilis calls could significantly reduce the population of P. pica in the cherry orchards (P<0.05), and scare the C. cyana and Passer montanus. The pest birds had different behaviors to respond different bird-driving modes, and thus, it would be necessary to adopt comprehensive techniques and measure cost-profit efficiency, and to establish effective assessment mechanism in pest bird control management.
