"Hummingbird on the Left."

"Huitzilopochtli, Aztec God of Sun and War."

Huitzilopochtli's name is a combination of two Nahuatl (or Aztecan) words, huitzilin, meaning hummingbird, and opochtli, which means left — the god's name translates literally as "Hummingbird on the Left." This resulted in Huitzilopochtli often being depicted as a blue- or green-colored hummingbird or as a warrior whose armor and helmet were made of hummingbird features....

Huitzilopochtli's mother was Coatlicue, and his father was a ball of feathers....

His sister, Coyolxauhqui, tried to kill their mother because she became pregnant in a shameful way (by a ball of feathers). Her offspring, Huitzilopochtli, learned of this plan while still in the womb, and before it was put into action, sprang from his mother's womb fully grown and fully armed. He then killed his sister Coyolxauhqui and many of his 400 brothers. He tossed his sister's head into the sky, where it became the moon, so that his mother would be comforted in seeing her daughter in the sky every night. He threw his other brothers and sisters into the sky, where they became the stars.
