Readers of all ages will enjoy this factual, fun-filled introduction to loons, ancient birds that have inhabited our planet's northern waters since about the time dinosaurs died out. This lively and informative book covers loon history, physiology, behavior, and coexistence with humans, with plenty of information for young researchers and older enthusiasts. Gorgeous paintings bring the text alive, showing loons diving, swimming, preening, raising chicks, and acting, well, just plain "loony." Suggested activities for home or classroom provide opportunities for further exploration of loons as kids learn how to walk, paddle, and float like a loon. An appendix offers more information on all five species of loons found worldwide. A bibliography provides a list of books and web addresses fro continued study. For ages 8 and up.
