No, this Raven was not dead. It kept scratching to the right, just below its beak. It would then go into a small pool of water and wet its upper part. Shake and then repeat few more time. Then it would drag itself in the snow, shake side to side, followed by scratching. It kept repeating these steps for about twenty minutes or so before it flew away. Not sure if it was grooming or trying to remove something.
Until next moment,
