On Sunday, Austin Ahmasuk went along the beach to his camp at the Sinuk River, about 28 miles from Nome, and shortly after hitting West Beach past the port, he found one dead seabird on the shore.

Carcasses examined so far have shown no indication of disease, and tests are pending for harmful algal toxins. Seabirds have been found emaciated and starved, and changed ocean conditions may have affected prey.

For the second year in a row, dead seabirds are washing up on beaches throughout the region by the hundreds. The birds appear to be starving, but scientists say the story is more complicated.
