Why owl pellets

When an Owl is about to produce a pellet, it will take on a pained expression - the eyes are closed, the facial disc narrow, and the bird will be reluctant to fly. At the moment of expulsion, the neck is stretched up and forward, the beak is opened, and the pellet simply drops out without any retching or spitting movements. Owl pellets differ from other birds of prey in that they contain a greater proportion of food residue.

The likely reason why the owl is the symbol for Athena was because of the inspiration for the Greek goddess. Lilith was the goddess of death who had talons for feet and was flanked by owls.
