Here's a surprise: Wild crows can recognize individual people. They can pick a person out of a crowd, follow them, and remember them — apparently for years. But people — even people who love crows — usually can't tell them apart. So what we have for you are two experiments that tell this story.
First, how do crows tell us apart? Watch this video:
Now, our second experiment. On you.
There are crow scholars who raise, study, and even live with a crow. But once that crow flies off and joins a group, these researchers say they can no longer tell their crow apart from the others.
So let's see how well you do:
If you want to hear researchers describe what it's like to alienate a crow, and then be razzed and harassed by its family and neighbors wherever they go — tennis courts, ATM machines, parking lots — listen to our radio story. We'll also tell you how unbelievably long a crow can keep a grudge.
