"Bird beaks work like human tools. With a guessing game that will engage young readers, this simple but effective title demonstrates how the distinctive beaks of different bird species reflect the ways they use them. Each right-hand page asks readers to guess the kind of bird whose bill is shaped like a particular tool: a straw, a strainer, needlenose pliers, and so forth. The bird is shown in silhouette with the tool where its beak would be. A page turn reveals the answer. Hummingbirds have beaks that are long and hollow like straws, allowing them to poke deep into narrow blossoms for nectar. Slater's collage illustrations show recognizable examples, along with other birds with similar beaks, both labeled and named in an added, asterisked note. The circles of light surrounding the silhouettes are repeated in the circles around the notes, a pleasing bit of design.

Finally, the author suggests some other uses for beaks besides eating, concluding with gannets, who show affection by clapping their beaks together. She suggests that readers do the same with their hands to show their affection for birds. The illustrator thoughtfully depicts a Black girl bird-watcher and younger White boy doing just that, by the light of a circular moon. The backmatter extends the exploration of beak differences to introduce the idea of evolutionary change over time. A useful addition to the nature shelf."--Kirkus Reviews.
