Furthermore, corvids exhibit a capacity for what psychologists call "mental time travel"—the ability to recall specific past events and anticipate future needs. Western scrub-jays are habitual hoarders, caching thousands of food items across their territory every autumn. In a seminal study led by Nicola Clayton, jays were allowed to cache both crickets (a favorite but perishable delicacy) and peanuts (a less preferred but durable option). If allowed to recover their caches after a short interval, the birds chose the crickets. However, if a long period had elapsed, they skipped the crickets entirely and dug up the peanuts, proving they remembered exactly how much time had passed and understood the concept of decay. the intelligence of corvids ielts reading answers

One of the most compelling demonstrations of corvid intellect lies in their sophisticated use and manufacture of tools. While primates like chimpanzees use sticks to fish for termites, New Caledonian crows take this a step further. In laboratory settings conducted by researchers at Oxford University, a crow named Betty was presented with a straight piece of wire and a deep bucket containing meat. Spontaneously, Betty wedged the tip of the wire into a crack and pulled the other end to create a hook, allowing her to lift the bucket. This action demonstrated causal reasoning rather than trial-and-error learning, as she had never encountered wire before. learn from other birds , a captive crow
Found in Paragraph B: "...they meticulously sculpt them into hooks to extract grubs..." wax worms (or perishable wax worms )
Without prior training, the rooks successfully selected heavy, solid objects (like stones) over light, hollow objects (like polystyrene) to drop into the tube. They calculated that only heavy items would displace the water and raise the reward to the top. When practicing this passage, ensure you can trace the exact sequence of this experiment, as it is a prime target for flow-chart or diagram labeling questions.
