The largest gathering of seabirds on the planet.

A humpback whale dives for krill amidst thousands of short-tailed shearwaters. It is mid-summer in the Bering Sea, off Alaska’s Aleutian islands. Cold water and long sunny days leads to some of the richest seas in the world. Humpbacks have travelled for months from Hawaii and shearwaters the length of the planet from Australia. Filming from the boat, the BBC watched shearwaters accidentally fly straight into the side of breaching whales, and humpbacks accidentally swallow and spit out shearwaters. At 18 million, this is the largest gathering of seabirds on the planet
