Little naturalists-in-training can travel the world via Sounds in the Wild, where ring-tailed lemurs swing through the jungles of Madagascar, elephant seals tussle on the beaches of South Georgia Island, and baby polar bears play in the snow in frozen Svalbard. Sounds of the Sky transports young readers to the Serengeti, where ostriches race; to Canada, where bald eagles soar; to Norway, where puffins call….Each volume showcases nine different locations illustrated with drawings of endangered animals and cool facts about them. Best of all? With the press of a button, kids can listen to a wild sound (such as the call of a ptarmigan or the song of a humpback whale) from each place. Embark upon an incredible journey of discovery! Sold separately.
