The Intelligence Of Corvids Ielts Reading Answers Fix File
Western scrub-jays demonstrate a capacity once thought unique to humans: planning for the future and remembering the specific past. In caching experiments, these birds remember not only where they hid food, but what kind of food it was (perishable vs. non-perishable) and when they hid it. 3. Theory of Mind and Social Cognition
This refers to "false caching" or building decoy nests to mislead potential thieves or predators. Corvids recognize individual birds Answer Location: Usually Paragraph 3 or 4.
Furthermore, corvids exhibit future planning. In experiments where ravens were given a tool that could open a box containing a reward, but were separated from the box for 15 minutes, the ravens chose to carry the tool with them, saving it for later. They delayed gratification intentionally, a sign of .
Explanation: The passage highlights that the crows "spontaneously bend the wire," meaning it occurs without prior human instruction or explicit training.
Scientists believe corvid intelligence evolved to manage complex social hierarchies. the intelligence of corvids ielts reading answers
For decades, scientists believed only humans could remember the past and plan for the specific needs of the future (episodic memory). Corvids, particularly Western scrub-jays, challenge this theory. The passage details how these birds cache (hide) food. If a scrub-jay knows it will be in a room without breakfast the next morning, it will proactively cache food in that specific location the previous evening. Social Intelligence and Theory of Mind
Shifts focus to scrub-jays, caching behaviors, and the concept of mental time travel.
tested the ability of captive jackdaws to count, a skill apparently related to their communication often being based on the number of calls. First, Koehler trained jackdaws to expect five food rewards. Then the jackdaws were given a number of boxes, some of which contained food. They proceeded to open the boxes until they had found five pieces of food, at which point they stopped opening boxes because they knew they had reached five. In another experiment, Koehler also trained jackdaws to choose a box with the same number of dots on the lid as the number of dots on a cue card.
Theory of Mind refers to the ability to attribute mental states—such as knowledge, intents, and beliefs—to oneself and others. Corvids show clear signs of tactical deception and perspective-taking. If a scrub-jay is watched by a rival while caching food, it will later return to dig up the cache and re-hide it in a private location once the competitor has left. This indicates that the bird understands the rival's visual perspective and potential future intent to steal. 4. Casual Reasoning and Problem Solving Furthermore, corvids exhibit future planning
The IELTS Reading test frequently features academic articles exploring animal behavior, cognition, and evolutionary biology. One of the most popular and intellectually stimulating topics encountered by test-takers is the remarkable intelligence of corvids—the bird family that includes crows, ravens, rooks, jays, and magpies.

Ravens remember individual "friends" for years.
Furthermore, corvids have demonstrated an understanding of basic physical principles, such as water displacement. In a modern replication of Aesop’s fable "The Crow and the Pitcher," researchers presented Eurasian jays and New Caledonian crows with a treat floating on water inside a deep tube, just out of the bird's reach. The birds were provided with a variety of objects, including heavy stones and light plastic baubles. Remarkably, the corvids consistently chose the heavy objects that sank, discarding the floating ones. They also showed a preference for dropping items into tubes filled with water rather than tubes filled with sand, proving that they understood which medium would allow the food reward to rise. This capacity for causal reasoning suggests that their brains can form abstract concepts about the physical laws governing their environment.
