Three-legged Bird (Asia and Africa)
The three-legged (or tripedal) crow is a mythological creature in various mythologies and arts of East Asia. It is believed to inhabit and represent the Sun. The Chinese have several versions of crow and crow-Sun tales. But the most popular depiction and myth of the Sun crow is that of the Yangwu or Jinwu, the "golden crow".
