形形色色的海洋鳥類~ Hints: the whales' industry-sea birds forage Cape Petrels breed howling gale

Other creatures benefit from the whales' industry-sea birds forage in their wake. As the whales drive the krill closer to the surface, it comes within reach of birds that are not particularly skilled in diving. Cape Petrels, about the size of pigeons, can only duck dive a few feet down. But that is enough to give them a share.
360 million sea birds constantly scour the southern ocean for food. They only go to land to breed. Most of their lives are spent on the wing far out at sea. This ocean is rich in nutrients and very rough. Howling gales whip it into huge waves. These, with so few islands to interrupt and break them, grow and grow into some of the most mountainous seas to be found in any ocean.
