摘要识别巢穴捕食者是了解鸟类面临的捕食压力的关键，而使用监控摄像头似乎是识别巢穴捕食者最可靠的方法。然而，摄像设备的存在和使用方法可能会导致捕食率的偏差。为了总结摄像头对鸟巢成功的潜在影响，我们回顾了已发表和未发表的研究，这些研究估计了在有和没有监控摄像头的情况下每天对鸟巢的捕食。我们使用Meta分析从独立研究中定量地合成了这些影响的方向和大小。我们发现，有证据表明，平均而言，使用摄像设备可能会降低鸟巢捕食率，尽管这些差异并不总是显著的，而且与地理区域、植被类型和研究持续时间有关。使用摄像头监视鸟巢的研究人员必须意识到，这些设备可能会影响捕食率，并可能对收集的捕食者身份数据产生偏差。基于我们的回顾和分析，我们为寻求最大限度地减少或控制使用监控摄像头监控巢穴捕食时的潜在偏差的研究人员提供了建议。
Abstract Identifying nest predators is critical to understanding predation pressures that birds face, and using surveillance cameras appears to be the most reliable method of nest predator identification. However, presence and methods of using camera equipment may introduce bias in predation rates. To summarize potential effects of cameras on nest success we reviewed published and unpublished studies that estimated daily nest predation for bird nests with and without surveillance cameras. We used meta-analyses to quantitatively synthesize the direction and magnitude of these effects from independent studies. We found evidence that, on average, use of camera equipment may reduce nest predation rates, although these differences were not always significant and varied relative to geographic regions, vegetation types, and study duration. Researchers using camera surveillance to monitor nests must be aware that the equipment may be affecting rates of predation and possibly biasing data collected on predator identity. Based on our review and analysis, we provide recommendations for researchers seeking to minimize or control for potential bias when using surveillance cameras to monitor nest predation.
