The Intelligence Of Corvids Ielts Reading Answers Extra Quality High Quality

Despite lacking a neocortex (the mammalian seat of higher intelligence), corvids pack neurons densely in their forebrain. The pallium in birds is functionally analogous to the primate prefrontal cortex. Researchers argue that high neuron density—up to 1.5 billion neurons in some ravens—enables complex cognition without large overall brain mass. Thus, brain size is a poor indicator; it is neural packing and connectivity that matter.

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.
