Ivo Jacobs studies the evolution of cognition at Lund University in Sweden. Corvids like crows possess surprising cognitive capacities similar to great apes, despite a massive evolutionary gap.
Misconceptions about corvids are rife: they are often viewed as unpleasant and dangerous birds, but they are more likely to gently preen your eyebrows than to try plucking out your eyes.
Our corvids enjoy participating in research, essentially playtime for food rewards, so much that they compete to enter the testing area.
This suggests that complex cognition has evolved independently several times, demonstrating how creatures like crows adapt to their environments with impressive problem-solving abilities.
