The largest inland colony of Caspian terns in the West is taking a big bite out of endangered fish runs in the upper Columbia River.
Though just a fraction of the size of coastal colonies, the 900-some terns living on an island near Moses Lake are single-handedly blamed for eating more than 10 percent of the wild upper Columbia steelhead juveniles and nearly 15 percent of the hatchery steelhead young as they make their way to the ocean each spring.
