Researchers found that crows could distinguish between individual human faces by conducting field experiments where they wore different masks while capturing and banding crows. The birds would later react differently to the masks, showing aggression towards those associated with negative experiences while remaining calm around neutral or positive ones. This demonstrated that crows not only remember human faces but also associate them with specific actions and emotions.
