How does air trapped in feathers slow down heat loss from the body of birds?

The base layer of feathers on birds contain small, fluffy, and extremely soft shafted feathers called the down. These are the feathers used in making pillows, comforters and clothing. They provide the insulation needed to protect and maintain their body temperatures during cooler temperatures.
When temperatures heat up, however, birds can often be seen "sunning" themselves. By opening their wings and spreading their feathers apart they are able to produce a cooling affect by increasing air circulation. Turning their backs to the sun with the feathers in this position will reflect the sun's rays rather than absorbing them. This also acts to shade their legs and feet which are not insulated.

∙ 14y agoSwifts and Swallows will 'brush' their chest feathers (very fine down like feathers) in water by skimming over pools of water and taking this back to the nest to let the young drink and they shake it over them to cool them. Birds also pant in the shade. Other birds have 'washed' and then sun dried to clean and cool I guess. Hope this helps

∙ 15y agoBirds 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.
