: This paragraph focuses extensively on the New Caledonian crow's ability to use tools. It explicitly notes they can modify objects ("fashioning hooks out of straight pieces of wire") and create tools that "do not yet exist in nature," which aligns with "tool manipulation and creation."
But the intelligence of corvids extends far beyond tool use. Professor John Marzloff at the University of Washington demonstrated that American crows possess a remarkable ability: facial recognition. To test this, researchers donned a caveman mask while capturing, tagging, and releasing several crows on campus. Later, when any researcher, wearing the same caveman mask, walked around the campus, the crows would immediately recognize the perceived "threat," mobbing and cawing at them. Even crows that had not been originally captured joined in the harassment, learning from others in their flock. When a person walked by without the mask, they received no reaction at all, proving it was the face the crows had learned to hate. As a testament to their problem-solving depth, when researchers wore the mask upside down, some crows tilted their own heads, trying to reorient the upside-down face to ensure the identity was correct.
