Abstract
The spread of human development has caused a dramatic increase in noise across the landscape. Recent studies suggest that noise may negatively impact wildlife, yet little is known about the causes and consequences of this impact. Furthermore, most previous studies have not been designed to isolate noise impacts from other confounding factors. This study is investigating the impacts of energy development noise on greater sage grouse (Centrocercus urophasianus), a species of management concern across western North America. Sage grouse are declining in areas of energy development and circumstantial evidence suggests that noise is a cause of this decline. To test this hypothesis, control leks and leks with experimentally‐introduced energy development noise were monitored. Results from three seasons of experimental noise playback will be presented, comparing lek attendance, territory selection, and display behavior between noise and control leks. This is the first long‐term playback experiment investigating the chronic impacts of noise on any wild population, offering a unique opportunity to experimentally address noise impacts on avian behavior and breeding site selection while informing conservation efforts for this species.
