Huitzilopochtli is the “hummingbird of the south.”

Huitzilopochtli was the father of the Aztecs and the supreme god of the Mexicans. His nagual, or animal spirit, was the eagle. Unlike many other Aztec deities, Huitzilopochtli was essentially a Mexican deity with no counterpart in the earlier cultures of Mesoamerica.
He was both the Aztec god of war, the Aztec sun god, and the god of Tenochtitlan. This inextricably linked the “hunger” of the gods to the Aztec penchant for ritual warfare. His sanctuary was located at the top of the Templo Major pyramid in the Aztec capital and was decorated with skulls and painted red, symbolizing blood.

In Aztec mythology, Huitzilopochtli feuded with his sister and moon goddess Coyolxauhqui. Thus, the sun and moon were constantly fighting for control of the sky. It was believed that Huitzilopochtli was accompanied by the spirits of fallen warriors, whose spirits returned to earth in the form of hummingbirds, and the spirits of women who died in childbirth.
