Birds are able to control their body temperatures in different environments.As winters approach, birds get ready for the cold weather and the warm weather during the summers. Their ability to regulate body temperatures is uncanny.Birds are known to be direct descendants of dinosaurs. Dinosaurs were cold-blooded animals. But it’s surprising how their direct descendants do not have this quality. Birds have evolved over the period of years. They can regulate and control their body temperatures in any extreme environment. They are able to survive very efficiently through the harshest of colds. There is so much to know about birds and their warm-blooded bodies. Just like birds, mammals are also warm-blooded animals. But reptiles remain cold-blooded.The internal science behind birds not shivering in cold is quite interesting to know. After reading more about the science behind these animals being cold-blooded, do check our other articles on where do birds go when it rains and are birds animals?Are birds cold-blooded?Birds evolved from the reptiles we call dinosaurs. Dinosaurs were all cold-blooded creatures. Their body temperature used to be constant and did not change at all even if the outside temperature changed a lot. These mechanisms are not that efficient to survive in winters.Birds are warm-blooded (endothermic). They can keep warm in winters. Birds do not have a constant body temperature. They are able to process the changing temperature of their surroundings. Birds can, thus, regulate the temperature of their bodies accordingly. They do not change the rate of their metabolism as the environment around them changes. Endothermic birds are very well suited for survival as they can maintain themselves perfectly in extreme heat as well as cold. Due to all these reasons, birds prove to be warm-blooded rather than being cold-blooded as the dinosaurs.Bird Body TemperaturesBirds are capable of regulating their body temperature to adapt to their surroundings. They have a higher body temperature than mammals. This is because of the extensive feathers present on their body. Feathers of birds are known to be better insulators than the hair of mammals.Small birds have high body temperature as compared to large birds who have low body temperature. This is observed because of the fact that small birds have a higher rate of metabolism. All birds usually maintain their body temperature at around 37°C (98.6°F). During the winters or in cold environments, birds increase the temperature of certain body parts beyond 37°C (98.6°F) to keep warm. While in summers or warm environments, birds decrease the temperature of certain body parts below 37°C (98.6°F) to cool off.Do birds hibernate?Mammals are known to hibernate throughout the winter. But birds, on the other hand, do not tend to hibernate. They do not feel the need to hibernate. They rather use alternative methods to survive the winter. Because they have learned to survive without hibernating. Though there are a few species that are exceptions to this.Birds choose migration over hibernation. During the winter in their native areas, they migrate to warmer areas. Those who are unable to travel large distances to get away from the cold decide to hibernate. The common poorwill and black-capped chickadees are species of birds who are exceptions to the migrating clause. These birds live in large and insulated nests to keep warm. There is very little food available to insect-eating birds in winters. They use the fat stored in their bodies to gain the energy required to produce the necessary heat.How do birds cope with cold in winter?There are many methods that birds use to stay warm in winter. Even with the coldest surfaces, they can generate sufficient body heat to stay warm. One such method is shivering. They shiver their bodies to generate body heat. Their higher need for energy becomes prominent during this time. They spend a lot of energy maintaining their body heat.Birds are seen together in groups in winter. Many such groups cuddle together to generate body heat. They even tuck their beaks and legs in the feathers to maintain the heat. Many birds even like to trap pockets of air in their wings. This causes their feathers to fluff. During the night, birds like to sleep in free trees that can provide heat. As the night falls they go to their pre-selected nesting areas to sleep. They spend the nights there and come out when the sun comes up.Best Bird Food For WinterBirds rely on food available in their surroundings during the winter. They do not travel long distances to just search for food in cold weather. There are certain foods which can serve best to the birds. Such foods even help them regulate their body temperature.Foods containing fat will be a very good option for birds in winter. Foods like fish, suet, and worms will best serve the purpose. Aside from that, sunflower seeds, peanuts, corn, and fruits are also good bird foods for winter. If you are feeding your pet birds or even keeping out food for outside birds make sure you are cleaning the food area regularly. The food can attract insects which can infect the birds and cause health problems.How to help keep birds warm?Sometimes it is better for humans to take responsibility for protecting a few birds in the winter months. You can take a few measures to ensure birds in your area are well fed and warm during the cold.You can put out shelters outside your house to let the birds sleep at night. The shelter should be wooden and have proper insulation. Scatter bird foods in your backyard or outside the window throughout the day. Keep the area clean and free of any harm to birds. Some birds are shy and do not approach the feeding area in the presence of humans. If you sense the habitat of such birds around you then stay away from the feeding area so that they can eat freely.Here at Kidadl, we have carefully created lots of interesting family-friendly facts for everyone to enjoy!
