Club-winged Manakin: Beauty and Evolution

The video explores the unique courtship display of the Club-winged Manakin, a South American bird that sings with its wings. The male's wing bones are adapted to produce a distinctive sound, compromising flight ability for beauty. This adaptation is a result of female mate choice, leading to both males and females inheriting these traits. The concept of 'evolution of decadence' is introduced, where mate choice can oppose natural selection.
