Arab Weather - As the leaves turn brown and cold winds begin to sweep across the Northern Hemisphere, animals need to prepare for the coming winter months. Animals adopt a variety of strategies to cope with the cold and survive, including migration, hibernation, hiding, changing fur, and storing food. Here are six different tactics that animals use to prepare for winter:
When temperatures drop, many animals migrate south in search of warmer climates. Migration is especially common among birds, who take long journeys to avoid harsh weather.
For example, geese, which fly in a V formation, are among the most famous migratory birds, and some mammals, such as caribou and whales, also have long, winding migration paths in search of warmth.
Because they lack the ability to adapt to cold, some animals have evolved to hibernate. While bears are notorious for their inactivity, hibernation occurs when an animal's body temperature and metabolic activity drop. Some animals, such as reptiles and amphibians, enter a state of inactivity known as hibernation, where they lower their heart rate and body temperature to conserve energy.
Many animals that stay in the winter tend to spend their time hiding in protected environments such as holes in the ground.
For example, moles dig deeper tunnels to avoid freezing. Other animals, such as mice and starlings, spend most of their time in tunnels under the snow, where they provide protection and food.
Some animals, such as deer and foxes, use a strategy of changing their fur to survive the winter. Animals grow a thick layer of fur to keep their bodies warm, and they also change colors to match their surroundings, such as when snowshoe hares change from brown to white to avoid predators.
With winter being difficult to find food, some animals resort to storing large quantities of food before winter sets in. Squirrels, for example, search for nuts and seeds and hide them in secret places to eat later. Some animals gain weight in preparation for winter by storing food in their stomachs.
Animals adapt to environmental changes by developing new behaviors and characteristics that help them survive. For example, some birds change their feeding behavior and look for new sources of food, while other animals may have to change their nesting sites to provide protection from harsh conditions.
Through these different tactics, animals are able to face the challenges that arise in winter, ensuring their survival until the arrival of spring.
