The - Intelligence Of Corvids Ielts Reading Answers Extra Quality Best

Perhaps the most striking demonstration of corvid intelligence is their ability to use and manufacture tools. The New Caledonian crow, for instance, is known to craft hooks from twigs to extract insects from tree bark. Unlike instinctive behaviours, this skill is learned and refined through observation and experience. In controlled experiments, these crows have spontaneously bent wires into hooks to retrieve out-of-reach food, a feat not mastered by most primates without training. Similarly, rooks have been observed dropping stones into a water-filled tube to raise the water level – a behaviour reminiscent of Aesop’s fable – indicating an understanding of cause and effect.

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. In controlled experiments, these birds have been observed
