When Mother Earth bids goodnight, / the world is bathed in silver light. / She says, "Goodnight, my precious ones." / Nature's song has just begun.  
Mother Earth's Lullaby is a gentle bedtime call to some of the world's most endangered animals. Rhythm, rhyme, and repetition create a quiet moment for children burrowing down in their own beds for the night, imparting a sense that even the most endangered animals feel safe at this peaceful time of day. In successive spreads, a baby giant panda, yellow-footed rock wallaby, California condor, Ariel toucan, American red wolf, Sumatran tiger, polar bear, Javan rhinoceros, Vaquita dolphin, Northern spotted owl, Hawaiian goose, and Key deer are snuggled to sleep by attentive parents in their dens and nests under the moon and stars.
Brief descriptions of each animal appear in the back of the book.
