We investigated colony size, productivity, and limiting factors for five piscivorous waterbird species nesting at 18 locations
on the Columbia Plateau (Washington) during 2004–2010 with emphasis on species with a history of salmonid
(Oncorhynchus spp.) depredation. Numbers of nesting Caspian terns (Hydroprogne caspia) and double-crested cormorants
(Phalacrocorax auritus) were stable...
The status of the double-crested cormorant (Phalacrocorax auritus) in western North America was last evaluated during 1987–2003. In the interim, concern has grown over the potential impact of predation by double-crested cormorants on juvenile salmonids (Oncorhynchus spp.), particularly in the Columbia Basin and along the Pacific coast where some salmonids...
Colony size, nesting ecology and diet of Caspian Terns (Hydroprogne caspia) were investigated
in the San Francisco Bay area (SFBA) during 2003-2009 to assess the potential for conservation of the tern
breeding population and possible negative effects of predation on survival of juvenile salmonids (Oncorhynchus spp.). Numbers of breeding Caspian...
