The corax tribe first appeared in White Wolf's Werewolf: The Apocolypse - Player's Guide, p 148 - 153, and has been given their own book, the Corax tribebook, released February '98. For LARP rules, you can look in Laws of the Wild (p 238) for a really, really short blurb, or check out the expanded (and in my opinion, much better) Corax LARP rules in Laws of the Wild West - they're much closer to the way the corax are described in their tribebook.
The concept of shape-changing birds has been around for centuries before White Wolf picked it up, however.
Long before White Wolf's books defined the gothic-horror roleplaying world, people allowed their imaginations to lead them on flights of fancy, without worrying about the technical details and 'game mechanics' of these creatures. I think that's still the best way to look at the world of role-playing: let your imagination soar, and only consult the rulebooks when you run amuck. White Wolf may have published guidelines for the Corax, but don't consider them the end-all and be-all of the race. Follow your instincts. The rest is just details.
And with no further ado, here's the meat:
Oh yeah - and if you haven't guessed it yet, that odd shaped in the background stars is the glyph for Corax. You can get all sorts of fun glyphs at the White Wolf homepage, or click here for the just corax glyph (of course, its still copyright of White Wolf.)
Just as a note, I have nothing against White Wolf... more against people who consider the White Wolf to be the ultimate authority on gothic horror roleplaying. WW has put together a very popular system, but its still just a system. In the end, it's up to each player and each storyteller to decide for themselves how much of the rules they want to use, and how much is for the birds.
