I see people repeatedly confuse crows with ravens. Which is admittedly fairly easy to do. This is somewhat helpful. I would also look online or with local park rangers to see if one or the other are actually found in your area if you’re still not sure from looking at one. The difference in size alone can be a good indicator. I know many want to collect bits they may have left behind for workings. Or see their appearance as significant. So do your research first!
Dirthamen. (God of secrets and knowledge in elven pantheon of Dragon Age universe.)
is the twin brother of Falon'Din. He is also known as a "twin soul” to
Falon'Din, rather than merely a twin. Dirthamen is the elven god of
secrets and knowledge, and master of the ravens Fear and Deceit, having
found them in the Fade and outsmarted them both.“ (da-wiki)
In Native American mythology these birds are greatly respected. Some southwestern tribes believed the raven was a bringer of light that escaped from the darkness. They associated the raven with creation because it brought light where there was none. In other tribes the raven and crow were thought to be tricksters and the guardians of sacred and secret mysteries.
Ravens are associated with psychic powers and their feathers can be used to aid the clairvoyance.
In Celtic mythology the Goddess Morrigahn often appears in the shape of a raven or crow or is accompanied by a group of them. If they are seen in a group of three it means that Morrigahn is watching or preparing to pay someone a visit. Because the Raven is Morrigahns bird some believed that the bird has special visionary powers.
Western cultures believe that the raven or crow bring bad luck and death.
In Greek mythology Athena and Apollo kept ravens but turned them black when they couldn’t keep their secrets. Originally they had white feathers. The raven was said to be a method of divination. The aguars in ancient Greek used the colors of the ravens and and the direction of flight to interpret messages.
According to Welsh mythology the ravens were the hare bringers of death. They believed that witches and sorcerers would turn into ravens to avoid capture.
In Norse mythology Odin was represented with two ravens.
In parts of the Appalachian mountains, a low-flying group of crows means that illness is coming, but if a crow flies over a house and calls three times, that means an impending death in the family. If the crows call in the morning before the other birds get a chance to sing, it’s going to rain. Despite their role as messengers of doom and gloom, it’s bad luck to kill a crow. If you accidentally do so, you’re supposed to bury it but be sure to wear black when you do.
The raven is also frequently linked with prophecy, further enhancing its status as a bird of the occult. Not only was it a messenger of the gods, both as an informant and as a guide, but it also was thought to be the most prophetic of all birds.
