How do birds keep cool during summer with their feathers?
Birds often find some sand or cool earth and dig a slight depression then get into the hole and spread their wings out. This allows for air movement all over. In the hot summer they open their beaks and “pant” and they position their head into whatever breeze they are able to find allowing air to get to the wattle and combs on their head. The wattle and combs carry blood close to the surface of their skin and helps to cool the bird.
