Check out what a reviewer at Children's Literature had to say: 

"Did you know a woodpecker’s tongue is so long it curls around the back of its skull? Did you know that male songbirds tend to sing more than females? These are just a couple of the fun facts young readers will uncover in this clever nonfiction picture book about birds. The text is jam-packed with amusing bird information. However, the sections are a bit disjointed. The text is structured in part by bird behaviors, with many pages covering general topics like migration, soaring and gliding, and nesting. But intermixed are other pages about specific birds, like woodpeckers and geese. The back-and forth between general bird behavior and specific bird information can be a bit puzzling. Further, the book lacks a table of contents and clear headings, so finding details about a particular bird or behavior can be difficult. The cartoon-like illustrations (of both birds and bird watchers) are cute and fairly accurate, but the color photos that accompany the glossary of national birds at the end of the book are the most engaging visual elements, showing readers the vast differences in the sizes, colors, and features of the world’s birds. Younger elementary-aged children enamored with our feathered friends should greatly enjoy this title. It would also be a welcome addition for classrooms and libraries, and would be a great title to highlight during winter. Includes a lot of great information about birds flying south as the days get shorter."
