It is a body produced by the skin of water birds, on the belly and under the wings, to protect the vital parts during their migratory journeys.

      The down is made of long and fine barbs called barbules and contrary to the feather, has no shaft. Its origine is the same as the scales of reptiles, the ancestors of birds.      

Exceptional properties

      As for wool and hair, the α and β keratins help the down to resist  physical and chemical agents. This explains its longevity.
Retaining the air in its multiple filaments, the down is an excellent heat insulator, all the more effective since it favours the circulation of steam.
