The Intelligence Of Corvids Ielts Reading Answers Extra Quality Portable

One of the most striking examples comes from New Caledonian crows. In controlled experiments, these birds have been observed bending straight wires into hooks to retrieve food from tubes—a behaviour once considered unique to humans and a few primates. More remarkably, they display metatool use : using one tool to obtain another, more effective tool. A famous 2007 study showed a crow named Betty spontaneously bending a wire without prior training, suggesting not just trial-and-error learning but genuine insight.

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.
