Do Wild Animals Remember the Humans Who Wronged Them?

You walk past a crow on a wire and never think about it again. The crow might not be so forgetful. This one is about the wild animals that remember one specific human face, the one that once wronged them, and hold onto it for years. A mockingbird that learns to pick a single person out of a crowded campus. Crows that chased a researcher's rubber mask for years, and passed the warning on to birds that were never even there, until you had a reputation in crow society you did not know existed. Elephants that can tell one group of people from another by smell alone. It is not revenge, and that is the strangest part. It is something older, and a lot more useful than a grudge. Thanks for watching, I really hope you enjoy this one. Based on real research from the University of Florida, the University of Washington, and the University of St Andrews.
