In many parts of the world, winter brings frigid temperatures. Snow often covers the ground and vegetation like bushes. Flowers, berries and acorns provide food for many animals. But they don't grow during the winter months. So, animals can't find much food to eat.
In spring, everything comes back to life. Flowers grow. Leaves and berries grow on trees. There is plenty of grass to eat. Animals have plenty of food. However, when winter comes returns, they are again confronted with a lack of food.
So, how do animals survive the long cold, harsh winter months? Different animals have different methods of survival. These methods are hibernation, migration, gathering and storing, and foraging.
Animals that hibernate eat lots of food before the winter months. Some build up large stores of fat in their bodies. Then they sleep during the winter months. Their bodies use the stored fat to survive. Some types of bears, bats, and snakes hibernate. Bumblebees die off during the winter but the queen hibernates and then gives birth to new bees in the spring.
Many parts of the world don't have harsh winters. There are places where it never snows. Areas in the tropics always have mild climate. The tropics are areas close to the equator. Many animals leave cold areas as winter approaches and move toward warmer areas. This is called migration. Then they return home in the spring. Monarch Butterflies are migrating animals. They migrate from cold Canada to warmer Mexico to survive the winter. Canada Geese migrate from Canada, Alaska, and some other northern states, to states further south like California and Georgia. Some even fly to Mexico.
Gather and Store
Some animals gather up large amounts of food and then store it somewhere safe. Squirrels are a good example. They gather acorns, which grow on oak trees. They hide the acorns for use during the winter. These animals often sleep through much of the winter, but they wake up regularly to eat.
Some animals survive by foraging. This means they search for whatever food is available. They may survive on grass, leaves, lichens, or any other plants that can survive during the winter. Caribou or reindeer are an example of foraging animals that live in the northern regions of North America, Europe, Asia, and Greenland. They largely survive on lichen during the winter. Lichens are organisms that can live in extreme environments, such as arctic areas. They grow on soil, wood, rocks, and tree bark.
