Well, lucky for all of us, a FIREPAW animal research contributor has sent over some scientific study findings compiled on birds. Chances are high most readers do not know about some of these fun facts so we thought we would share them here:
Pigeons can discriminate “good” and “bad” paintings by children.
Published in the U.S. National Institutes of Health, PubMed, of all places, this study investigated whether pigeons could be trained to discriminate between “bad” and “good” art. More specifically, paintings that had been judged by humans as either “bad” or “good”. Never mind that this study rests on the somewhat shaky foundation of human judgment of “good” and “bad” art (which is subjective as all get up), you can read a brief overview of the study and findings here.
Pigeons’ discrimination of paintings by Monet and Picasso
Also published in the U.S. National Institutes of Health, PubMed, this study investigated whether pigeons could be trained to discriminate between impressionists and cubists paintings. This seems less about bird intelligence (long established in the animal sciences field) than the fact that there is apparently an endless supply of things with which researchers are willing to train birds.

Friend or Foe? Crows Never Forget a Face, It Seems
This is a piece in the New York Times that appeared several years back highlighting the fact that birds recognize faces, or more accurately, masks of human faces and will act out towards those ‘faces’ that have trapped them in the past.
“To test the birds’ recognition of faces separately from that of clothing, gait and other individual human characteristics, Dr. Marzluff and two students wore rubber masks. He designated a caveman mask as “dangerous” and, in a deliberate gesture of civic generosity, a Dick Cheney mask as “neutral.” <Several people at FIREPAW take issue with this “neutral” designation.> Researchers in the dangerous mask then trapped and banded seven crows on the university’s campus in Seattle.
“In the months that followed, the researchers and volunteers donned the masks on campus, this time walking prescribed routes and not bothering crows.
The crows had not forgotten. They scolded people in the dangerous mask significantly more than they did before they were trapped, even when the mask was disguised with a hat or worn upside down. The neutral mask provoked little reaction.
The effect has not only persisted, but also multiplied over the past two years. Wearing the dangerous mask on one recent walk through campus, Dr. Marzluff said, he was scolded by 47 of the 53 crows he encountered, many more than had experienced or witnessed the initial trapping. The researchers hypothesize that crows learn to recognize threatening humans from both parents and others in their flock.”
