Takes an in-depth look at the lives and natural history of the world's true seabirds - the penguins, tubenoses, peleceaniids, gulls, terns, skuas and auks. These birds all spend much of their lives foraging at sea, but they have evolved a different ways to exploit the marine environment whilst being able to return to land to breed. They range from the albatrosses, which take their prey from the surface of the water and are capable of efficient gliding flight for hours on end, to the penguins which have dispensed with flight altogether and have developed a morphology and physiology which enables them to dive deeper and for longer than any other bird.
