Contaminant Exposure and Effects on Osprey Nesting Along the Lower Duwamish River, Washington, 2006-2007
Active
The Lower Duwamish Waterway (LDW) in Seattle, Washington was added to the Environmental Protection Agency’s Superfund Site List in 2001. This 5.4 mile river segment includes the Duwamish marine river system and Elliot Bay estuary in the Puget Sound. The segment supports an anadromous fishery, migratory birds, and five federally-listed species. Commercial and industrial operations on the LDW have introduced chemicals of potential concern, mostly associated with sediments. These chemicals have been documented to cause injury in fish species. In 2003 and 2004, the Biomonitoring of Environmental Status and Trends Program funded a study of the Osprey population that recently started nesting along the Duwamish River. The objective of this study is to assess injury to nesting Ospreys by evaluating bird physiology, reproductive success, tissue concentrations, forage locations, and fish species consumed. The preliminary data provides information important for the National Resource Damage and Assessment program for the LDW.
