《Wilderness Babies》 - 免费有声读物

This book tells the stories of some of the baby mammals of the wilderness,—how they grow and learn day by day to take care of themselves. In hollow trees or down under water among the lily leaves, in the cool sea or on the rugged mountains, on the grassy plains or among the waving tree-tops, in the dark caves and burrows or hidden in the tangles underfoot,—all the world is alive with young creatures. - Summary by introduction
