||In some places, the weather is cold and snowy. In others, it's rainy and cool. People help birds find food by putting up bird feeders in their backyards. Days are shorter and nights are longer, and kids find more indoor activities to fill their afternoons. What does it all mean? It must be winter! From changes in the growth cycles of plants to the signs of winter that can be found in backyards, parks, woodlands, wetlands, cities, and farms across North America, this fact-filled book will give kids an exciting opportunity to explore nature in action.
