This is an interesting book because it is interactive, allowing readers to actually hear the sounds of birds in their natural environment. Organized by habitat--rainforest, mountains, desert, prairie, woods, ice, wetlands, city, ocean, and bush--each double-page spread features 6-7 birds, providing a brief description of its sound along with a "press here" button to hear one birdsong per group. The final double-page repeats the sounds (actually it is where the playback equipment is housed) and offers an overview of what a bird is, as well as information on the different orders of birds. The sound buttons are repeated with information on the habitats.
Two cautions: because of the choking hazard from the small sound producing part, the book is not for young children (3 and under) and because the sound producing part is in the back cover it can sometimes take a bit of pressure to produce the sound. The sounds in the book were created in association with Cornell Lab of Ornithology. Although it is not possible to identify individual birds in most cases, the book does offer a rare opportunity for kids to hear the sounds of emus, penguins, and other far-flung birds, and they will love creating a cacophony of sound by pushing the buttons. The illustrations are colorful and appealing and reasonably realistic enough to help with identification. The book was a 2019 Outstanding Science Trade Book for Students: K–12 (National Science Teachers Association and the Children's Book Council).
