The Intelligence Of Corvids Ielts Reading Answers Extra Quality -

Beyond physical problem-solving, corvids display remarkable social intelligence, specifically through their capacity for episodic-like memory and mental time travel. Western scrub-jays ( Aphelocoma californica ), for instance, practice caching, a behavior where they hide thousands of food items across vast geographic areas for future consumption. Laboratory experiments have proved that these jays remember not just where they hid the food, but also what type of food they cached and when they cached it. If a jay caches both perishable mealworms and non-perishable pine nuts, it will return to retrieve the mealworms first. If too much time elapses, the bird intelligently abandons the decaying worms and targets the durable nuts instead. This demonstrates a clear understanding of temporal decay, once thought unique to humans. Paragraph E

Furthermore, corvids possess an extraordinary capacity for facial recognition and long-term memory retention. In a landmark study conducted at the University of Washington, researchers wearing distinct rubber masks trapped and banded wild crows. Years later, the crows—and notably, their offspring who had never encountered the researchers—harshly scolded and mobbed individuals wearing those specific masks, while ignoring control masks. This indicates not only an acute ability to identify individual human faces but also the presence of cultural transmission, where vital survival information is actively communicated across generations without direct experience.
