Ha, that’s great. I also heard something once about the beak being either yellow or black, and the bird being larger or smaller, but haven’t researched it. But I think your point, Stephen, is also something along the lines of we don’t have to squabble over differences as miniscule as “a pinion.” (I couldn’t resist 🙂
But underneath the humor, a valuable point (for me, at least): Raven or Crow, don’t overthink it. I’m glad we, as mythologists, have the leisure of backing out of the math and getting back into the enjoyment and experience of encountering the figure and the story, itself.
