Whats the story behind why owls and crows enemies?

They say that once you see a crow, its the symbol of death. How ever in Mexico its different because a lot of people right away symbolize it as death or the incoming of death. they're many stories behind crows but its meaning is death.

The owls symbolizes as the eye of the Devil. Going back to Mexico, once you see an owl it means that the Devil is trying to kill you or has come for you. When i went to Mexico me and my girl were having sex and then this owl appeared out of no where and had red eyes and then we ignored it and then we were hearing things coming towards us and it was a lot of owls.

hope this is what you were trying to find out.
