The Raven is considered a trickster because of its transforming/changing qualities, to some tribes.
Native American Symbols, like the Raven symbol, can vary in meaning from one tribe to another and across the culture groups of North America.
The meaning of the Raven symbol signifies that danger has passed and that good luck would follow. According to Native American legends and myths of some tribes the Raven played a part in their Creation myth. The raven escaped from the darkness of the cosmos and became the bringer of light to the world. The raven is associated with the creation myth because it brought light where there was only darkness. The raven is also believed to be a messenger of the spirit world. It is believed that ravens who fly high toward the heavens take prayers from the people to the spirit world and, in turn, bring back messages from the spiritual realm. Other tribes looked upon the raven as a trickster, or shape-shifter, because of its ability to adapt to different situations.
