Archosis
I’m fascinated by this idea, not only the muelos belief, but considered as a general explanatory principle. The long paleolithic imprinted various atavisms, but only some have archotic force. (Some could be awakened). I suspect that Ted Hughes would have been interested in this idea, had he read La Barre, which he very well might have.
Owls eat crows. (And ducks. I was startled at night walking through the Duck Pond neighborhood in Gainesville by swooping owls intent on ducklings more than once.)
