Briefing summarizes Year 1 results from a bird monitoring study by Dan Cristol comparing mercury levels at contaminated and reference sites. Adult tree swallows, belted kingfishers, and screech-owls had about tenfold higher blood mercury (~2 ppm vs 0.2 ppm) at contaminated sites; some terrestrial species also showed elevated levels. Year 2 objectives include exposure-route studies, fledgling tracking, waterfowl sampling, and return-rate monitoring.
