EARTHFLIGHT: Video: Cape Gannets and the Great Sardine Run

In this scene from EARTHFLIGHT: Africa, Cape gannets fly off the coast of South Africa in search of the great sardine run, the biggest fish migration in the world. The birds dive into the ocean to feast as the dolphins, also on the hunt, push the sardines toward the water’s surface. It doesn’t take long before bronze whaler sharks and bride whales join them.
