Pigeons can learn to tell a Monet from a Picasso, and recognize new paintings by each
Researchers rewarded pigeons for pecking one way at Monet paintings and another way at Picassos. The birds not only learned the distinction — they correctly sorted paintings by each artist they'd never seen before, and even generalized from Monet to similar Impressionists like Renoir, and from Picasso to fellow Cubists like Braque.
