This offering from the Safari Animal Families series (12 titles) begins with an explanation of why groups of wildebeests, or gnus, are called confusions. Presumably the term is based on wildebeests’ tendency to clump together in big bunches, occasionally even trampling one another. Subsequent chapters provide information on gnu varieties, habitats and life cycles, and the critical role of wildebeests’ annual migrations play in maintaining Africa’s grassland ecosystem. Sidebars bring up interesting tidbits, such as how zebras and wildebeests coexist peacefully and mutually benefit from each other’s presence, and how wildebeests’ noisy snorting may contribute to their reputations as confusions. Full-page color photos abound, and ample back matter includes open-ended discussion questions, a mapping activity, a glossary, and resources. This will appeal to researchers and animal enthusiasts alike.

Animal group dynamics are the central topic in this well-organized series. Readers learn how each animal family is structured, including leadership, hierarchies, and the various roles different members play. Details about behaviors, such as hunting, mating, and child rearing are all described within the context of the group. Zebras and wildebeests, for example, work together to avoid predation, while hyenas and cheetahs team up for hunting. Unique characteristics of the featured group, like the warthogs’ use of burrows (A Sounder of Warthogs), are noted in a short chapter. Visuals include multiple photos showing individual animals, young and full-grown, and larger groups, along with a range map and a size comparison diagram. A final chapter notes the importance of each group and current threats to their survival. All animals covered in this series exist in ­Africa, though several are found on other continents as well. VERDICT Well-rounded, useful information about wild animal families.
