Paired acoustic and camera trap detections of Australasian Grass-Owl (Tyto longimembris) across diel and seasonal scales in southwestern Taiwan

This dataset contains paired detection records of Australasian Grass-Owl (Tyto longimembris) collected using autonomous recording units (ARUs) and perch-mounted camera traps across two river systems in southwestern Taiwan (Zengwen–Yanshui and Kaoping). Monitoring was conducted over a full annual cycle to assess diel and seasonal patterns of owl activity and to compare the performance of acoustic and visual passive monitoring methods. Data are provided in two temporal resolutions, 1) Hourly dataset (2Data_Hour_combine.csv): Binary presence–absence records aggregated at the hourly level for both camera traps and acoustic recorders. 2) Daily dataset (3Data_Day_combine.csv): Binary presence–absence records aggregated at the daily level. Each dataset includes matched observations from both monitoring methods at the same stations and time intervals, allowing direct comparison of detection outcomes (both detected, camera-only, recorder-only, neither). The dataset includes both full sampling data and effort-standardized subsets used for cross-site comparison.本数据集收录了通过自主录音设备（ARUs）与栖架式红外相机陷阱，在台湾西南部两条河流流域（曾文-盐水溪流域与高屏溪流域）采集的澳洲草鸮（Tyto longimembris）配对检测记录。本监测覆盖完整年度周期，旨在探究该鸮类的昼夜与季节活动模式，并对比声学与视觉被动监测方法的性能表现。数据集提供两种时间分辨率的数据：1）小时级数据集（2Data_Hour_combine.csv）：针对红外相机与声学记录仪，按小时尺度聚合的二元存在-缺失记录；2）日级数据集（3Data_Day_combine.csv）：按日尺度聚合的二元存在-缺失记录。每份数据集均包含两种监测方法在同一站点、同一时间区间内的匹配观测数据，可直接对比四类检测结果：两者均检出、仅红外相机检出、仅声学记录仪检出、两者均未检出。本数据集同时包含完整采样数据与用于跨站点对比的采样投入标准化子集。
