What should you do if you discover eggs, egg cases, or galls when you're exploring the outdoors? You should watch and wait and come back to check on them! Author Sara Levine's simple, lyrical text encourages readers to take time to observe eggs. Accompanied by photos of many types of eggs, egg cases, and galls, this book explains which ones you can safely collect and which you should leave behind. Back matter provides more information about featured eggs, egg cases, and galls—including the creatures that hatch from them—and expands on how to care for them at home or in the classroom.
