Automatic acoustic detections of four owl species using SILIC in Meishan, Yushan National Park, Taiwan

This dataset summarizes species-specific nocturnal vocal activity of four owl species—Mountain Scops-Owl (Otus spilocephalus), Collared Owlet (Taenioptynx brodiei), Collared Scops-Owl (Otus lettia), and Northern Boobook (Ninox japonica)—recorded via passive acoustic monitoring (PAM) from January to December 2023 at Meishan, Yushan National Park, Taiwan. Using an AI-based sound recognition model (SILIC ver. exp32), 705,512 vocalizations were detected and classified from 1,946 hours of nighttime (1600-0800) audio recordings.

The dataset provides fine-scale temporal, environmental, lunar and acoustic metadata for each occurrence, supporting future ecological studies, species distribution modeling, and long-term acoustic monitoring of nocturnal forest birds.
