AVS-P-08-02 is a continuation of previously funded work in 2008 through 2012 that investigated the nesting ecology, food habits, and predation rates on juvenile salmonids by double-crested cormorants nesting at the colony on East Sand Island in the Columbia River estuary. During the 2011 and 2012 contract years, research on the feasibility of methods for limiting or reducing the size of the double-crested cormorant colony on East Sand Island was conducted.
