The norse god Odin often put on a disguse to walk among humans in order to gather information. The motif of the grey wanderer can be found in the character of Gandalf in Lord of the Rings as well.
Maybe Odin is using that method to visit the mortals to this very day? The ravens Huginn and Muninn are appearing here in the form of pigeons, the wolfs geri and freki accompany the one-eyed god as Huskies.
