How do birds survive in cold weather?
Dear Sharmila,
Many birds like storks move to warmer areas before winter and stay there until winter is over. That way, they can stay warm and find food as well. Other birds stay together as a flock in the winter and eat fatty foods, like black-oil sunflower seeds, as much as possible. After they have eaten enough, they get puffy and rest. Feathers, in addition to protecting the birds from the cold air, also help trap body heat, thus keeping them warm.
Small birds look for small nooks to nestle in, while some others like the kinglets and chickadees lower their body temperature to save energy.
