1.自动声学记录器广泛使用，可以提供一种高效的物种监测方法，特别是在与自动数据处理软件相结合时。然而，由于缺乏与现有人工实地调查的直接比较，这些技术的采用受到限制。我们评估了自主方法的性能，通过比较手动和自动检查的录音与现场收听调查，使用市售的自主录音机和自定义呼叫检测和分类软件。我们比较了这三种方法的检测能力，时间要求，区域覆盖和天气条件的偏差，使用一个既定的呼叫监测程序的夜间鸟类，小斑点猕猴桃（Apteryx owenii）。自主记录法具有很高的精度（>98%），
1. Autonomous acoustic recorders are widely available and can provide a highly efficient method of species monitoring, especially when coupled with software to automate data processing. However, the adoption of these techniques is restricted by a lack of direct comparisons with existing manual field surveys.2. We assessed the performance of autonomous methods by comparing manual and automated examination of acoustic recordings with a field-listening survey, using commercially available autonomous recorders and custom call detection and classification software. We compared the detection capability, time requirements, areal coverage and weather condition bias of these three methods using an established call monitoring programme for a nocturnal bird, the little spotted kiwi (Apteryx owenii).3. The autonomous recorder methods had very high precision (>98%) and required
