The Impact Of Anthropogenic Noise On Northern Saw-Whet Owl (Aegolius Acadius) Hunting Behavior, James Tate Mason
Boise State University Theses and Dissertations
Anthropogenic noise has increased dramatically worldwide which has negatively impacted wildlife. The effect of noise on acoustically specialized predators has received limited attention. Here I demonstrate that noise generated by a natural gas compressor station degrades the ability of the northern saw-whet owl (Aegolius acadius) to detect and capture prey in the absence of light. The saw-whet owl is considered an acoustic specialist because it exhibits a high degree of ear asymmetry, an adaptation for precise three-dimensional sound localization in birds. I presented 31 wild-caught saw-whet owls with mice (Mus musculus) inside a flight tent under …

Negative impacts from anthropogenic noise are well documented for many wildlife taxa. Investigations of the effects of noise on bats however, have not been conducted outside of the laboratory. Bats that hunt arthropods rely on auditory information to forage. Part of this acoustic information can fall within the spectrum of anthropogenic noise, which can potentially interfere with signal reception and processing. Compressor stations associated with natural gas extraction produce broadband noise 24 hours a day, 365 days a year. With over half a million producing gas wells in the U.S. this infrastructure is a major source of noise pollution across …
