www.pwrc.usgs.gov — This research project gives an overview of the hormonal control and the effects of endocrine-active contaminants on avian secondary sex characteristics. This project will develop measures for plumage, soft parts (bill and dermal structures) color and pattern in American kestrels (Falco sparverius). In addition, experiments will characterize the More...

www.werc.usgs.gov — Mercury is a contaminant of significant concern in waterbirds because it can accumulate to high concentrations in their tissues and cause deleterious effects such as impaired reproduction. Numerous studies and monitoring programs have evaluated concentrations of mercury in waterbird tissues as an index of risk to exposure. However, no single More...
