The hoatzin is not hard to identify; not only does it have a blue face and red eyes—it smells bad! In this entertaining book, Professor Oddfeather offers bite-sized facts on the hoatzin's habitat in South America, what makes them hoot and squawk so much, why they smell, and who is in their family tree. A "Battle of the Birds" comparison pits the hoatzin against a Guinea turaco. Downloadable Teacher Notes available.
