The Dawn of the World: Beliefs Concerning Animals: Soo-koo'-me The Great Horned Owl
The Dawn of the World, by C. Hart Merriam, [1910]
The Middle Mewuk of Tuolumne River foothills say:
When Soo-koo'-me the Great Horned Owl hoots, it means that someone is dying. He is himself the Ghosts of dead people. 20
[I was once asked by a Northern Mewuk if I had ever seen the broad belt of bony plates which surrounds the eyeball of the Great Horned Owl. On replying that I had, I was assured that these closely imbricating plates are the "finger nails all jammed tight together of the ghosts caught by the owl."]
