Scientists are trying to send Columbia River's Caspian terns packing. The world's largest nesting site of terns is at the mouth of the river and their favorite food is the smorgasbord of endangered salmon and steelhead that pass by.
Oregon State University scientists believe the terns and cormorants eat more than 10 million juvenile fish a year -- somewhere around 10 percent of the total population passing through the river.
So with $2.1 million in funding from the U.S. Army Corps of Engineers and the Bonneville Power Administration, the birds are being lured to a new nesting site on the recently restored Crump Lake in southern Oregon. The researchers used decoys and recorded sounds of nesting terns to draw them away.
