Introduction: Why Corvids Matter for IELTS If you have been preparing for the IELTS Academic Reading test, you may have encountered a passage about "The Intelligence of Corvids."

Social intelligence is another hallmark of corvids. Ravens have been observed manipulating competitors during food sharing. They lead rivals away from hidden carcasses using deceptive behavior, only to double back alone. This tactical deception requires "theory of mind"—the ability to infer another's knowledge state. While once considered unique to humans, theory of mind in corvids suggests convergent evolution: different brain structures solving similar ecological problems. D (episodic) 7
Beyond tool manufacture, corvids possess what psychologists call "episodic memory"—the ability to recall specific past events, including what happened, where, and when. In a landmark study at the University of Cambridge, scrub jays ( Aphelocoma californica ) cached food in two distinct locations. They learned that one type of food perished quickly while the other remained edible. When recovering their caches later, the jays preferentially searched for the durable food first, ignoring the perishable item. This indicates they mentally traveled back in time to encode the what-where-when of their caching.
