bad paintings and the researchers noted which paintings they pecked at. The scientists said the pigeons consistently pecked at the
good paintings more often than the
Artistic endeavors have been long thought to be limited to humans, Watanabe said.
But this experiment shows that, with training, pigeons are "¦ able to acquire the ability to judge beauty similar to that of humans.
