Description:From 2003 to 2005, we detected the passive integrated transponder (PIT) tags of 200,000 juvenile Pacific salmonids Oncorhynchus spp. on abandoned piscivorous bird colonies in the Columbia River Basin. These tags had not been previously detected, and total detections of PIT tags on colonies accounted for as much as 4% of all PIT-tagged salmonids released into the Columbia River Basin in some migration years. The majority of tags were detected on colonies of the Caspian tern Sterna caspia and double-crested cormorant Phalacrocorax auritas. These species are the major avian piscivores in the Columbia River estuary and in Lake Wallula.
