In Antarctica, the coldest spot on the planet, male Emperor penguins perform one of the most difficult tasks in the natural world. For two months, in the middle of winter, they take care of the eggs laid by females who are out at sea hunting for food. This book explains this phenomenon with simple, fact-filled text and beautiful blue-tinged illustrations. It is a wonderful study in natural history as well as an eye-opening lesson for students about male and female parenting roles in nature.
