The Intelligence Of Corvids Ielts Reading Answers Better »

While many animals use objects as tools, corvids stand out because they can manufacture them. The passage frequently highlights the New Caledonian crow ( Corvus moneduloides ). In the wild and in laboratory settings, these birds fashion hooks from twigs and rip leaves into barbed tools to fish for insects. This demonstrates a high level of causal reasoning and physical intelligence, once thought unique to primates. Future Planning and Mental Time Travel

Scientific passages rely heavily on cause-and-effect structures. For every experiment mentioned, quickly underline the subject (e.g., New Caledonian crow), the task (e.g., wire bending), and the conclusion (e.g., abstract planning). This simplifies scanning for matching features or summary completions.

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 —the ability to understand that modifying an object changes its physical effect on the environment. the intelligence of corvids ielts reading answers

Paragraph F discusses how advanced intelligence evolved along parallel paths in both mammals and birds despite separating 300 million years ago. It explicitly names this phenomenon as "convergent evolution," making heading vii the correct choice. 7. Answer: TRUE

The text will alternate between terms like intelligence, cognition, mental faculties, insight, reasoning, and shrewdness . Do not just scan for the word "intelligence." While many animals use objects as tools, corvids

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."

While many animals use tools, corvids—particularly the New Caledonian crow ( Corvus moneduloides )—demonstrate the rare ability to manufacture and modify them. In wild and laboratory settings, these birds select specific twigs, strip them of leaves, and fashion hooks to retrieve insects from deep crevices. When presented with unfamiliar materials in experiments, such as straight pieces of wire, they spontaneously bend the wire into hooks to retrieve food baskets from vertical tubes. This behavior signifies abstract planning rather than mere trial-and-error learning. 2. Mental Time Travel (Episodic Memory and Planning) This demonstrates a high level of causal reasoning

Corvids, a family of birds that includes crows, ravens, jays, and magpies, have long been recognized as one of the most intelligent bird groups. Their intelligence is often compared to that of primates, and they have been observed exhibiting complex behaviors that are rare in the animal kingdom.

Answer 10 Explanation: The behavior of re-hiding food away from rivals is explicitly termed "tactical deception" in the section on social dynamics. Key Vocabulary for IELTS Preparation

Paragraph C explicitly states that Betty's feat "required spontaneous innovation without prior training." Therefore, saying she had received extensive training is false. 9. Answer: FALSE
