The lives, diversity, and sheer mass of penguins are fascinating, and the remote, cold and beautiful areas in which they live are places to be treasured on Earth. Photographers Yva Momatiuk and John Eastcott travel to these places, from Antacrtica to the South Georgia Islands, and study these fascinating water birds, so awkward on land, and so at home in the sea. Their nesting habits, parenting customs, growth, development, diets, and interaction, are all covered with gripping fact and stunning pictures.
