Western scrub-jays will re-hide their food regardless of whether another bird is watching them or not.

: New Caledonian crows are famous for creating hooks from twigs and wire to retrieve food from deep cavities. Social Intelligence

Western scrub-jays prefer eating peanuts over crickets under normal circumstances.

Unlike animals that use tools by instinct, corvids demonstrate an understanding of cause and effect. New Caledonian crows, for instance, do not just find tools; they manufacture them. They modify twigs, leaves, and wire by bending them into hooks to extract larvae from deep crevices. 2. Mental Time Travel (Episodic Memory)

If you are asked for the main idea of the passage, the answer usually revolves around the fact that , despite having a completely different brain structure. This challenges the old "bird brain" stereotype and suggests that evolution can produce high intelligence in more than one way.

New Caledonian crows craft hooks from twigs.

However, the narrative shifts to the famous "wire-bending" experiment. Dr. Emery placed a small bucket of food at the bottom of a vertical tube. Beside it, he placed a straight piece of wire. The male crow, Abel, attempted to grab the bucket and failed. But Betty, the female, picked up the wire.

When this passage appears in the IELTS exam, it generally utilizes three primary question types. Understanding how to navigate them is critical to achieving a Band 7 or higher. Matching Scientist Names to Findings

Professor , at the University of Washington in Seattle, demonstrated another interesting ability in American crows: recognizing faces of individual humans. In 2005, he and other researchers each wore a Caveman mask when they captured, tagged, and then released crows on campus. Then Marzloff and other researchers took turns wearing the mask and walking around campus. Over time, increasing numbers of crows flocked together and cawed at anyone wearing the caveman mask, regardless of the size, gender, and skin color of the mask wearer or whether the wearer was one of the researchers who had originally captured crows. When the same people did not wear the mask, they got no reaction from the crows. This showed that it was clearly the face that was identified as a threat to the flock. Crows that had not originally been captured were joining the harassment of the perceived threat. When Marzloff suggested that researchers try wearing the caveman mask upside down, some crows actually turned their heads upside down to better identify the face of the "enemy."

Paragraph B focuses entirely on the physical brain structure of the bird. It highlights the "nidopallium," compares the crow's brain-to-body mass ratio to a chimpanzee, and explains how this anatomy supports executive functioning. This fits perfectly with "The anatomical basis of avian genius." 3. Answer: viii

For years, the scientific community placed corvids (the family including crows, ravens, rooks, and jays) in a category of "bird-brains," a term meant to imply stupidity. However, recent research has forced a rewrite of the textbooks.
