ABSTRACT: Energy development in the Western U.S. has led to an omnipresent influence on grassland birds such as the lesser prairie-chicken Tympanuchus pallidicinctus (hereafter LPC). Decreased reproductive success and geographical barriers can result from development. In this study, we assess the influence that noise pollution from energy development has on the nest success and placement by LPC, as well as the amount of sound LPC are exposed within their home ranges. To accomplish this we measured sound pressure level (SPL) at oil and gas (O/G) pump jack motors, nest sites, nest matched random and true random locations throughout Gove County, KS. Comparison of average sound exposure between core home range and outside core home range showed no significant difference. ANOVA comparing sound at nest sites significantly differed at 8Hz, 16Hz, 500Hz and 1000Hz (FDf=2, 247=4.96; P=0.0077, suggesting sound is a high order hierarchical factor determining nest placement. No significant difference was detected between successful and failed nests, indicating sound is not a determinant of nest success. However, a logistic regression showed a significant difference in sound at 32Hz between successful and failed nests (PDf=23, 19=0.070, R2=0.25), which suggests sound is a low order hierarchical factor influencing nest success. These results indicate that sound is a hierarchical factor influencing LPC by determining the placement of nests and home range, and influencing nest success.
