Fear may elicit behavioural and physiological responses in animals. We conducted a pilot study aiming to reduce bird nest predation in Tasmania by the introduced Sugar Glider (Petaurus breviceps) by broadcasting calls of predatory owls. We designed a solar‐powered, automated weatherproof stereo for long‐term call broadcast in a forest environment. This device may have useful applications in other environments where long‐term call broadcast is required in remote field conditions. Call broadcast did not reduce the likelihood of Sugar Glider nest predation on either active bird nests or artificial nests baited with farmed quail eggs. If we elicited fear in Sugar Glider individuals with call broadcast, this fear did not result in behavioural changes that could be exploited to achieve the conservation objective of lower predation.

自动广播捕食者的声音并没有减少糖滑翔机对鸟类的捕食压力

恐惧可能引起动物的行为和生理反应。我们进行了一项试点研究，旨在通过引入的Sugar Glider（Petaurus breviceps）减少塔斯马尼亚州的鸟巢捕食）广播捕食性猫头鹰的叫声。我们设计了一种太阳能自动防雨立体声音响，用于在森林环境中进行长期通话广播。在其他需要在远程现场条件下进行长期呼叫广播的环境中，此设备可能具有有用的应用程序。呼叫广播并没有减少在活动的鸟巢或用养殖的鹌鹑蛋诱饵的人工巢上发生糖滑翔机巢的可能性。如果我们通过电话广播在Sugar Glider个体中引起恐惧，那么这种恐惧不会导致可用于实现低捕食性保护目标的行为改变。
