If you watch this, I can almost guarantee that everyone near you will reach for their phone. It's a raven who was captured on video in Yellowstone National Park mimicking a smartphone ringtone.
Imagine what you would do in this situation. You're a deer (I realize that's a reach) and you're being chased by a coyote. What do you do? If you're in Yellowstone National Park, you hide in a nearby bison herd which is exactly what just happened as a new video shows.
