Babies and toddlers will have fun making page-turn predictions, and grown-ups will appreciate learning such eggcellent facts.

  • Dinosaur

Little learners will love this nonfiction guessing game book about animals, their eggs, and their habitats with perfect page-turn reveals!
Darrin Lunde has worked as a mammalogist at the American Museum of Natural History and at the Smithsonian Institute. His work has brought him into contact with all kinds of animals, big and small, throughout the remote forests of South America, Africa, and Asia where he camped for months at a time to survey species diversity and to discover new species. He is the author of Hello, Bumblebee Bat, a Theodor Seuss Geisel Award Honor Book, After the Kill, and other books about animals. He lives in Washington, DC. View titles by Darrin Lunde
Kelsey is an illustrator and lover of all things nature. Her work centers around an array of natural history subjects, often inspired by the myriad ways humans connect with and study the natural world. She received her first scat identification book around the age of 10 and loved that it helped her learn to identify the natural world around her. Her gouache illustrations focus on natural history subjects like taxonomy, biodiversity, and taxidermy, as well as related subjects like astronomy and the ways humans relate to the natural world. Her first book as an author, What We See in the Stars: An Illustrated Tour of the Night Sky, came out in Fall 2017. She lives in Minneapolis with her husband, Nick, and their two cats, Jamie and Fiona.

This board book adaptation follows the same format as the original, though slightly shorter in length. Readers are introduced to an egg with one defining characteristic pointed out, such as color, size, texture, or location, and asked the title question. Along with the egg are hints, such as a single ostrich feather, or a sandy beach with a tiny piece of ocean in the corner. The answer is revealed with the turn of the page, and the main characteristic is explained. A robin’s egg is bright blue because the color protects it from strong sunlight. An ostrich egg is the largest egg and can weigh more than three pounds. The realistic gouache illustrations depict the eggs in their natural habitat along with their parents in full detail. Readers might see a colony of emperor penguins with dads protecting their eggs from the snow and ice, or a small dinosaur hatching from a clutch of eggs in a prehistoric setting. Most eggs come from birds, but there are a few reptiles too, like the dinosaur and the loggerhead sea turtle, though the board book doesn’t show the mammal egg layer, the platypus. The final two pages show a few “eggcellent” egg facts, which will probably be less appreciated by a toddler audience than the bright pictures and simple statements of the earlier pages. Still, this is a fun introduction to a common element in the natural world.
