Wear feathers
The feathers are used to fly, to warm and to communicate. The reporter Pere Renom hunts ducks with his hands, visits a factory of down blankets, measures the colors of Great tits, observes the courtship of Sison and shows the great diversity of bird colors in a closet. And the presenter Jaume Vilalta explains how the down retains body heat and how is produced the iridescence of the feathers.
