The World's Biggest Birds

Each book introduces the class of animals in question before moving on to two chapters, each of which focuses on a different “biggest” animal. Basic info, with an emphasis on size, is provided. The authors employ child-friendly comparisons: school buses, cars, and average child or adult weight or height are frequent standards. “Did You Know?” insets extend the facts, while labels, simple graphs, and a world range map add value. Photos are clear and well chosen. A final graphic contrasts the height, weight, or length of one or both of the animals with humans, inviting further exploration. A quick “Try This!” activity that concludes each volume continues the math integration. VERDICT Young readers will find both the topic and treatment inviting as they are encouraged to interact with the text through questions and extensions. –School Library Journal (11/2015)
