Grades 2-5 – A fun, colorful nonfiction book about females in the animal kingdom. In the introduction, York explains her reasons for creating the book: “Male animals have historically received more attention than females. A major reason for this was that until relatively recently, the male scientists of our species were the ones who received most of the attention. Now that female scientists are getting the recognition they deserve, we are learning more about female animals than ever before.” Each double-page spread features either an animal or a general topic related to the females of various species (e.g., live birth, parthenogenesis, and migration). The text is engaging and written at a developmentally appropriate level for elementary grades. The book is vividly and effectively illustrated in color and is bookended by a table of contents, glossary, and index (unfortunately, no bibliography). The book’s subject matter raises the question of whether it further reinforces binary human gender norms by applying them to animal species, but simply from a different perspective than the male-dominated scientific paradigm of the past. This conceptual tension is evident, for example, on page 71 about clownfish, when the author writes, “Whether an animal is male or female is not always a simple question.” However, an accessible and interesting text about overlooked female animals is certainly still a welcome addition to the nonfiction catalog.
