The Intelligence Of Corvids Ielts Reading Answers Link

– Explanation: The passage explicitly describes a crow pretending to hide food in one spot while keeping it in its throat.

Crows can identify individual humans who have threatened them previously.

Tool use was once considered a defining trait of human beings. However, corvids have repeatedly shattered this notion. The New Caledonian crow, in particular, is renowned for its ability to manufacture and use tools in the wild. These crows fashion three distinct types of tools from pandanus leaves: wide, narrow, and tapered, each designed for specific foraging tasks. The manufacturing process involves ripping the serrated edge off the leaves, and the tapered design is created in steps, with the crow nipping the leaf, ripping along the fibres, making another cut and tearing again until it has a tool with usually two, three or four steps. This leaf tool manufacture is an example of culture: the birds learn through example and their tool-making wisdom grows in sophistication down the generations.

In IELTS Reading, candidates may encounter statements requiring True/False/Not Given judgments. Based on the research discussed: – Explanation: The passage explicitly describes a crow

The implications of corvid research extend far beyond ornithology. It challenges the classic evolutionary ladder, proving that advanced intelligence did not evolve in a single, linear path culminating in humans. Instead, mammalian and avian lineages split over 300 million years ago, yet both managed to evolve identical cognitive solutions to complex environmental challenges. This phenomenon, known as convergent evolution, suggests that nature has a limited blueprint for high-level intelligence, and that under the right evolutionary pressures, even a creature without a neocortex can become a genius.

Paragraph E describes how scrub-jays can remember the "what, where, and when" of past events. The experiment with the rotting wax worms proves they can track time and plan around the decay rate of food. This directly relates to heading iv. 6. Answer: vii

Western scrub-jays avoided eating wax worms that had been left for several days. However, corvids have repeatedly shattered this notion

Remember: the IELTS Reading section tests your ability to find and understand explicit information, identify writer claims, and follow logical argumentation—not your prior knowledge of birds. Even if you know that crows are intelligent, always base your answers solely on the passage provided.
