自主录音技术在过去十年中获得了相当大的吸引力，但问题仍然是它们是否可以取代人类观察调查来对发声动物进行采样。特别是对于鸟类，调查方法已经使用点计数和录音调查进行了广泛的测试。在这里，我们审查了最新的证据，这分类群的框架内的系统地图。我们比较了这两种调查方法的抽样效果，它们产生的输出变量，以及它们的实用性。当根据点计数的标准进行评估时，自主录音被证明是一个强大的工具，至少可以对许多物种进行采样。该技术可以以详尽、标准化和可验证的方式监测鸟类。此外，录音机可以访问整个音景，从中可以导出新的数据类型（声音活动，声学指数）。可以获得诸如丰度、密度、占有率或物种丰富度之类的变量，以产生与点计数相当且兼容的数据集。最后，自动声音记录器可以进行高时空分辨率和覆盖范围的调查，这更具成本效益，仅靠人类观察无法实现，尽管小规模研究在进行点计数时可能更具成本效益。录音机可以部署在许多地方，它们更可扩展和可靠，使它们成为越来越多的数据驱动的鸟类调查的更好选择。我们提供了目前可用的记录器的概述，并讨论其规格，以指导未来的研究设计。
Autonomous sound recording techniques have gained considerable traction in the last decade, but the question remains whether they can replace human observation surveys to sample sonant animals. For birds in particular, survey methods have been tested extensively using point counts and sound recording surveys. Here, we review the latest evidence for this taxon within the frame of a systematic map. We compare sampling effectiveness of these two survey methods, the output variables they produce, and their practicality. When assessed against the standard of point counts, autonomous sound recording proves to be a powerful tool that samples at least as many species. This technology can monitor birds in an exhaustive, standardized, and verifiable way. Moreover, sound recorders give access to entire soundscapes from which new data types can be derived (vocal activity, acoustic indices). Variables such as abundance, density, occupancy, or species richness can be obtained to yield data sets that are comparable to and compatible with point counts. Finally, autonomous sound recorders allow investigations at high temporal and spatial resolution and coverage, which are more cost effective and cannot be achieved by human observations alone, even though small-scale studies might be more cost effective when carried out with point counts. Sound recorders can be deployed in many places, they are more scalable and reliable, making them the better choice for bird surveys in an increasingly data-driven time. We provide an overview of currently available recorders and discuss their specifications to guide future study designs.
