While exact body temperatures vary from species to species, all wild birds have a higher body temperature than humans. Birds are able to adapt and use their instincts to make it through the winter months. Migration is one obvious way that birds manage the winter months. However, not all species do it – as you’ll realize by the numerous birds that stick around in your backyard even after the first snow hits. Here are four other ways birds adapt to the changing conditions of winter: 1. Feathers, a natural way to insulate themselves in the cold; 2. Preening, the oil-producing glands birds have and fluffing their feathers to create air pockets that trap body heat to keep them warm; 3. Food, storing food while the weather is still warm and changing their diet.; 4. Torpor, this state allows birds to lower their body temperature and heart rate to conserve body heat. Like hibernation, it helps them to survive the cold temperatures of winter.
