Crows can recognize geometric patterns, suggesting that humans aren't unique in understanding shape structure.

Scientists tested crows on their ability to recognize “geometric regularity,” a skill previously assumed to be unique to ...

A trio of animal physiologists at the University of Tübingen, in Germany, has found that at least one species of crow has the ability to recognize geometric regularity. In their study published in the ...

Crows in a lab were able to distinguish shapes that exhibited right angles, parallel lines, and symmetry, suggesting that, like humans, they have a special ability to perceive geometric regularity.
