Guardian: Studying the most smart bird laboratory in the world is forced to close the crow Queen to lose the scientific territory

China Well -off. June 20th. The 18 -year -old bird of Lao Mario is playing intellectual games.This is a classic cup and ball on the street corner.It's just that this time the venue is a cognitive laboratory of Madingley at the University of Cambridge, and the ball is a waxworm.

Rio is calm, blank, and firm, sitting on a wooden platform preparing to bet.A creeping food was placed under one of the three cups, and the order of the cup was disrupted in advance.Rio tilted his head and stabbed over with his sharp mouth, successful!

Professor Cryon is a crow research expert

The British Guardian reported that it picked up the wax insect from its mouth and then retreated to enjoy its prizes.Aristotle is a resident wearing a bright black feather jacket. It stays in the bird house almost as long as the laboratory life.

Together with reporters, the above game was Professor Clayton Nicola Clayton, a psychologist who founded the laboratory 22 years ago. Francesca Cornero, a 25 -year -old doctoral researcher, also joined our ranks (and occasionally as cups and ball game technicians).
