Everyone knows that birds have feathers, but why so many different colors and shapes? From feathers for flying, to feathers for swimming, feathers for camouflage, to feathers for attracting a mate, this book will give readers a fascinating insight into the lives of birds and their physical adaptations. Topics include how a chick's feathers change from fluffy down to its adult flight feathers, how the bright red and yellow feathers of a macaw can actually help it stay hidden among green rain forest trees, and how feathers help keep penguins warm in the coldest place on Earth. After reading, put your knowledge to the test with a simple science project.
