I'm writing a novel, and my main God, Daichi, Daichi is a ten-tailed fox who has a bird messenger. I was going to use a raven, but I wanted the bird to have differently-colored plumage from an ordinary bird. My main character (who is a half-fox spirit) is going to follow this bird to the sort of "heaven" for animal spirits. If you suggest the raven, then could you suggest what kind of colors I can use for the raven while it still looks like a raven.

ravens do exist in albino coloring http://media.nowpublic.net/images//1c/2/… very rare and IMO mystical looking

generally foxes are not seen hanging around with with birds, other than chickens which they eat
