Passive acoustic monitoring reveals surprising patterns of avian community antipredator behavior at a regional scale

The purpose of this study was to investigate how birds in the Sierra Nevada vocally respond to goshawk calls. The data were collected as part of a long-term passive acoustic monitoring project originally designed to monitor Spotted Owls (see Kelly et al. 2023, Ecological Indicators 154:110851).

Recordings were collected with Swift One autonomous recording units deployed in mixed conifer forest across 25,000 km2 of the Western slope of the Sierra Nevada. The present study only used audio collected in 2021 between the hours of 4:00-10:00 and 18:00-21:00. Calls were detected and identified to species using the artificial neural network BirdNET. The present data set consists of 5 .csv files with data and 1 .R file with code used to analyze those data.
