The Intelligence Of Corvids Ielts Reading Answers ((free)) Site

Answer: B

This IELTS Academic Reading passage explores the tool-making abilities of New Caledonian crows. According to the passage, the crows of New Caledonia rip the leaves of the pandanus tree to fashion three distinct types of tool for grub and insect extraction: wide, narrow, and tapered. The birds discovered that they could rip the serrated edge off the leaves to make a wide tool, and the skill spread as the crows honed tools with finer working tips. Leaf tool manufacture is an example of culture because the birds learn through example and their tool-making wisdom grows in sophistication down the generations. The crows appear to have the cognitive requirements for cumulative, though rudimentary, technological evolution.

In addition to social manipulation, certain corvid species have demonstrated a degree of self-awareness that remains elusive to most mammals. In 2008, researchers in Germany applied the classic "mirror self-recognition test" to Eurasian magpies ( Pica pica ). The scientists placed a brightly colored sticker on the magpies’ throats, a spot they could only perceive via a mirror. When placed in front of a reflective surface, the birds repeatedly scratched at the mark on their own bodies rather than attacking the reflection or ignoring it entirely. This behavior implies that the magpies recognized the mirror image as a reflection of themselves, shattering the long-held psychological dogma that self-awareness is restricted to a small handful of large-brained mammals like dolphins, elephants, and chimpanzees.

The IELTS Reading test frequently features academic articles exploring animal behavior and cognitive biology. One of the most popular and challenging topics encountered by test-takers is (the bird family that includes crows, ravens, rooks, jays, and magpies).

Ravens remember individual "friends" for years.

While obtaining is your immediate goal, the deeper value lies in recognising how academic texts are structured. Corvid passages typically move from anatomy (brain structure) to behaviour (tool use, memory, social tactics), then to comparison with other species (primates, dolphins), and finally to implications for animal cognition studies. Mastering this flow will help you predict content and locate answers faster.

She didn't just poke at the food. She assessed the problem. She held one end of the wire against the tube and used her beak to bend the other end into a hook. She then used this hooked tool to lift the bucket by the handle.

Corvids have a larger brain-to-body ratio than most other bird species.

Corvids also display remarkable social intelligence, including the ability to follow human voice commands. Researchers from the University of Cambridge found that a rook named Leo could learn three commands by sound alone, including "speak," "come here," and "wait". The researchers concluded that Leo could follow commands by sound alone, without relying on gestures or lip movements, and two more rooks showed the ability to learn the commands. The study suggests that animals don't need domestication to learn and follow human voices. In another example, six rooks at the Puy du Fou park in France were trained to pick up litter. The birds learned to associate tidying up with food rewards, though they would sometimes try to trick their trainer by dropping pieces of wood into the box instead of garbage.

When being observed by rivals, corvids utilize tactics involving both ____________ and counter-deception.
