As infrastructure expands across raptor breeding ranges, critical gaps remain in our understanding of how these species behaviorally respond to episodic and intense human disturbance. In close collaboration with the California Department of Transportation, this study investigates how the Swainson’s Hawk (Buteo swainsoni), a state-listed threatened species in California, responds to construction activities associated with the California High-Speed Rail (HSR) project in the Central Valley. Using high-frequency GPS/GSM telemetry (1-minute location intervals) and passive acoustic monitoring (PAM), this research assesses changes in hawk movement, nest attendance, perching/roosting, and hunting/foraging behavior in relation to construction intensity and noise levels. Behavioral states are classified via Hidden Markov Models, and habitat use is analyzed with resource and step selection functions. Construction activity will be quantified using a combination of audio-derived sound energy metrics and detailed daily construction reports. Rather than comparing across sites, this design tracks within-individual changes over time, enabling more precise inference of disturbance effects. Outcomes include identification of behavioral thresholds and activity-specific responses to fluctuating construction events. By integrating fine-scale spatial, behavioral, and acoustic data, this research will provide novel insight into how a long-distance migratory raptor navigates rapid, human-driven habitat change during the breeding season.
