The book covers numbers and dynamics, colony sites and locations, and prey contaminant levels, and compares them to other comparable coastal estuaries. It uses colonial waterbirds as the focal point for an ecosystem approach to metals that begins with prey fish and goes through invertebrates to humans. Additionally, it provides information based on long-term integrative studies the authors have done on metal levels and bird species and compares the findings with data from the Harbor Estuaries Program, other Northeast bays, the Great Lakes, and the Wadden Sea.
