Pigeons can tell people apart

Common street pigeons can tell people apart. 

Researchers in Paris learned that if you go to a local park and shoo a pigeon, he’ll remember and stay away from you. 

Likewise, if you give them food, they’ll chase you down and mob you for seeds. 

But amazingly, when two researchers changed coats, the birds were not fooled, even though the women were about the same age and had a similar skin color and build.
