Ravens Show Unexpected Geometric Skills

Researchers at the University of Tübingen have demonstrated that ravens possess the ability to recognize geometric regularity. In a study published in Science Advances, carrion crows were trained to identify an outlier shape amongst several similar ones. The crows successfully distinguished subtle differences in shapes, exhibiting an understanding of right angles, parallel lines, and symmetry. This challenges previous assumptions about animal cognition, suggesting this ability may be more widespread than previously thought.
