When you think of winter, which word comes to your mind? Cold, dark, snow, or ice? When the weather turns terrible, we can stay in warm houses and enjoy nice food, but wild animals may not have this fun. So how do animals spend the long cold winter months?
Some animals make journeys to warmer places once a year. We call this the migration. They sometimes travel thousands of miles to reach their winter home. Caribou(北美驯鹿) have one of the longest land migrations, travelling over 3,000 kilometres! But not all migrations are as long as the example. Some birds make shorter migrations from high mountains to lower lands to find better places with less snow and more food. This type of migration is about changes in height.
If winter makes you want to sleep, you’re not alone. Some animals hibernate for part or all of winter. This is a special, very deep sleep. There are a few different types of hibernation. For example, a bear will eat a lot of food to build up fat reserves. During hibernation, its body temperature drops, and its heart beats more slowly. A bear’s heartbeat may drop from around 55 beats per minute to just 9 beats. The bear can sleep for months without eating or drinking, using its fat for energy.
Instead of going to warmer places or sleeping through winter, some animals spend winter by changing bodies with seasons. Some animals may grow a thicker and warmer winter coat.
What about you? Will your mind, body or action change in wintertime? Do you go to a warmer place for holiday or just stay at your comfortable home? Or maybe you really enjoy taking part in some outdoor activities in winter. No matter how you like to spend winter, spring is just around the corner.
