You surely already know that different seasons change during the year. When autumn comes and after it winter comes cold and frost. But how do animals actually manage to survive outside in such conditions until spring? Do they stay in one place all year round? What do they eat when it snows? Aren't they cold? And can you help them somehow? You will learn all this in this beautifully illustrated book. Open the window and find out what migration and hibernation are, why animals suddenly grow white fur and if the sea is also cold.
