The most striking comparison is often made between corvids and young children. In a famous psychological test known as the "Marshmallow Test," a child is offered one treat now or two treats later. It tests impulse control.
Scientists replicated this with crows. The birds were offered a less preferred food item (like a piece of dried meat) or a token they could exchange later for a better food item (like sausage). The crows passed. They demonstrated the ability to think about the future—a trait once thought unique to humans and great apes.
In your IELTS exam, a question might ask: Do corvids demonstrate the ability to plan for the future? The answer is Yes. They possess metacognition—thinking about thinking—which allows them to delay gratification for a better reward.
When searching for "the intelligence of corvids ielts reading answers" in the future, remember that the real test will paraphrase the text. The word in the question may not match the word in the passage (e.g., "bend" for "manufacture," "rotten" for "decayed"). Focus on synonyms and logical connectors (however, therefore, for example). Corvids are smart—and so are you. Use their example of flexible problem-solving to adapt to any question type the test throws at you.
"The Intelligence of Corvids" IELTS passage highlights the advanced cognitive abilities of birds, including tool creation by New Caledonian crows, facial recognition, and social cooperation. Key question types often involve matching, multiple-choice, and summary completion focused on these specific behavioral experiments.

The Intelligence of Corvids Corvids, a family of birds including crows, ravens, and jays, are often called "feathered apes." Recent studies show their cognitive abilities rival those of primates. Researchers focus on their problem-solving, tool use, and social intelligence. Key Research Findings
Tool Manufacture: New Caledonian crows craft hooks from twigs.
Future Planning: Western scrub-jays cache food based on future hunger.
Social Recognition: Ravens remember individual "friends" for years. the intelligence of corvids ielts reading answers
Water Displacement: Crows use stones to raise water levels in tubes. IELTS Reading Passage Questions Questions 1–5: Matching Information
Match the following research behaviors to the correct bird species. Bending materials to create functional reaching tools. Adjusting food storage habits based on anticipated needs. Utilizing stones to access out-of-reach liquids.
Retaining memories of specific social interactions over time. Hiding food in multiple locations to prevent theft. Questions 6–10: True/False/Not Given
TFNG: Corvids have a larger brain-to-body ratio than most other bird species.
TFNG: The New Caledonian crow is the only bird known to use tools in the wild.
TFNG: Scientists believe corvid intelligence evolved to manage complex social hierarchies.
TFNG: Ravens are unable to distinguish between cooperative and uncooperative humans.
TFNG: Scrub-jays will re-hide their food if they notice another bird watching them. Answer Key 1 New Caledonian Crow 2 Western Scrub-jay 3 Common Crow / Rooks 4 5 Western Scrub-jay 6 7 8 9 10
Corvids, particularly scrub jays, cache (store) thousands of food items annually and recover them months later. More impressively, they remember: The most striking comparison is often made between
If another bird observed the caching, the original bird will later re-cache the food in secret—evidence of mental state attribution (understanding that another individual has knowledge).
Corvids are a family of passerine birds that includes crows, ravens, rooks, jackdaws, jays, magpies, and nutcrackers. Often referred to as "feathered apes" by some comparative ethologists, these birds have brain-to-body mass ratios comparable to great apes and dolphins. Unlike most birds, whose forebrains are structured for instinctual behaviours, corvids possess densely packed neurons in their pallium—the region analogous to the mammalian cerebral cortex.
Why should IELTS candidates care about corvid intelligence? Because the passage you just read is structurally identical to a typical IELTS Academic Reading passage. It contains:
When searching for "the intelligence of corvids ielts reading answers", students must learn to distinguish between main ideas (Corvids are as smart as primates) and supporting details (The wire-bending experiment). Below are three standard IELTS question types based on the article above.
Q1. The term "bird-brained" is now considered accurate by scientists.
Q2. Betty the Crow was the first animal observed using a tool.
Q3. Corvids use vocalizations to trick other birds.
Q4. In the water displacement experiment, rooks dropped objects randomly.
Q5. Corvids show similar levels of self-control to __________. If another bird observed the caching, the original
The IELTS Reading passage " The Intelligence of Corvids " explores the advanced cognitive abilities of birds such as
, often comparing their problem-solving skills to those of primates. Core Passage Content
The text highlights several key areas of corvid intelligence:
Tool Manufacture: Corvids, specifically New Caledonian crows, do not just use tools but manufacture them, such as making hooks from twigs or spears from leaves.
Social Learning: Because tool designs vary by region, researchers believe this behavior is cultural and learned from other crows.
Advanced Cognition: Studies show they can recognize human faces, remember "enemies," and display theory of mind by re-hiding food if they suspect they are being watched.
Cooperation and Counting: Rooks have shown the ability to work together to pull ropes for food, while jackdaws have demonstrated an ability to count up to five. Common Questions & Answers
Below is a summary of typical matching and multiple-choice answers found in this practice test: Question / Action Corresponding Intelligence Trait (Answer) Birds opened boxes to obtain food. Corvids can count. Birds pulled ropes to get food. Corvids can work together to achieve a goal. Birds hid food from other birds. Corvids recognize individual birds. Birds built a fake nest. Corvids protect themselves by tricking enemies.
Empathy Question: Corvids demonstrate empathy by consoling each other after a loss.
Survival Myth: It is False that their intelligence is solely focused on survival; they also engage in play and complex social emotions. IELTS Reading Tips
