Mercury impacts on birds in the Shenandoah River watershed

Three-year study plan to assess mercury effects on birds in the Shenandoah River watershed. Year 1 focuses on reproductive success and mercury availability in Tree Swallow and Belted Kingfisher, with nest monitoring, blood/feather/egg sampling, prey collection, and point-count surveys. Years 2–3 increase sampling and may include destructive tissue sampling and prey-base assessment.
