Raven Nibbles Then Hides Tortilla - January 19, 2015 - Video Attached
The Ravens would play with their Tortillas, take bites of them, fly them from one spot to another, and then hide them in the snow. Video shows the last two steps. She poked a hole in the snow. When the tortilla did not quite fit, she set it aside, dug deeper and then shoved it back in.
