Abstract
Why do some animals gather in family groups? How do they behave when they are in these groups? These and many other animal behavior questions are answered in these fascinating books. Penguins live in some of the harshest places on Earth. Although at home in the ocean, they are awkward on land, where they raise their chicks in huge colonies. There, they face constant threats from predators so they have to stick together. This book includes beautiful full-color photos and clear text, sidebars that offer additional information, glossary, further reading, websites, and index.
