The Intelligence Of Corvids Ielts Reading Answers Direct

Recent neuroanatomical studies reveal that while corvids lack a neocortex, they possess a high density of neurons packed into their pallium (the forebrain region). In fact, some corvids have a higher percentage of neurons in their forebrain than many primates. The result is a brain that, while physically small, performs computational feats that rival those of great apes. One of the clearest indicators of higher intelligence is the ability to not just use a tool, but to modify one. The New Caledonian crow is the poster child for this behavior. In controlled experiments, these crows were presented with a stick too short to reach a piece of food and a piece of wire. Without any training, the crows bent the wire into a hook to retrieve the food. This spontaneous manufacture of a novel tool demonstrates causal reasoning —the ability to understand that modifying an object changes its physical effect on the environment.

This is not instinct. In a famous experiment dubbed the "Metatool" test, crows had to use a short stick to retrieve a longer stick, which could then be used to retrieve food. This multi-step problem solving, known as , requires planning and an understanding of future needs, a trait once considered uniquely human. Episodic Memory and Planning for the Future For a long time, episodic memory—the ability to recall specific past events (what, where, and when)—was thought to belong only to humans. Western scrub-jays have disproven this. In landmark studies, these birds cached (stored) different types of food. They learned that one type of food (wax moths) decayed quickly, while another (peanuts) lasted longer. When allowed to recover their caches, the jays did not search randomly. They specifically went to the sites where peanuts were stored after a long delay, and to the wax moth sites immediately after caching. This shows they remembered what they hid, where they hid it, and when they hid it. Without any training, the crows bent the wire
