With hundreds of color photographs and precise illustrations, along with explanatory annotations, Birds examines all aspects of avian life evolutionary beginnings, biology, behavior. This comprehensive reference provides up-to-date information on the conservation status of various species at risk. It also describes how birds have adapted, and how they continue to cope with such inhospitable habitats as tropical rainforests, arid deserts and the frigid Antarctic continent. Readers will find detailed information about the remarkable phenomenon of avian migration across continents and oceans, which covers the mechanics of flight and the structure of feathers. The historical role of birds in literature and the arts is also included. "FactFiles," found throughout this book, provide quick access to essential facts on each bird species.
