Anthropogenic noise is one of the fastest growing, globally widespread pollutants, affecting countless species worldwide. Despite accumulating evidence of the negative impacts of wind turbines on wildlife, little is known about how the noise they generate affects ecological systems. Songbirds may be susceptible to noise pollution due to their reliance on vocal communication and thus, in this field study, we examined how songbirds are affected by wind turbine noise. We broadcasted noise produced by one wind turbine in a migratory stopover site during the nonbreeding season. Throughout the study, we repeatedly monitored the acoustic environment and songbird community before, during, …

The extent of artificial night light and anthropogenic noise (i.e., “light” and “noise”) impacts is global and has the capacity to threaten species across diverse ecosystems. Existing research involving impacts of light or noise has primarily focused on noise or light alone and single species; however, these stimuli often co-occur and little is known about how co-exposure influences wildlife and if and why species may vary in their responses. Here, we had three aims: (1) to investigate species-specific responses to light, noise, and the interaction between the two using a spatially explicit approach to model changes in abundance of 140 …

Owing to habitat loss, changes in farming practices, urbanization, and high mortality through vehicle collisions, barn owls Tyto alba are a species of conservation concern in portions of their range. This species can be secretive and difficult to survey, particularly away from breeding sites, so factors related to barn owl occurrence often remain unknown. We conducted nighttime broadcast surveys for barn owls during the early- and post-breeding seasons and used an occupancy modeling framework to understand how factors related to landcover, landscape features, and human development related to occupancy in southern Idaho, USA. We also assessed the effectiveness of using …
The Impact Of Anthropogenic Noise On Northern Saw-Whet Owl (Aegolius Acadius) Hunting Behavior, James Tate Mason
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 …
