An obsolete collective noun for a group of ravens (or at least the Common Raven) is an "unkindness".Somehow, I'm just not surprised. First, based on the stories from Jen and crew re: how ravens will tease puppies mercilessly....
And second, because as I was making my was to work this morning, I saw a raven HAPPILY MUNCHING ON A DISEMBODIED RAVEN LEG.
Initially I was just grossed out by the mini-gory site, but then I realized the bird had both "feet" on the disembodied "leg" and that they were THE EXACT SAME.
I was not impressed.
