Owl pellets are profoundly metaphorical to me. Owl swallows life whole, then later, vulnerable and alone, regurgitates the indigestible.
There is a cool place near me where owls have taken over the rafters of an old Lockheed site. Graffiti artists spatter the walls with color, and owls spatter the floor with pellets and nesting mess.
