The 2026 TOEFL iBT Speaking Task 4 requires a 60-second summary of an academic lecture. In an animal migration prompt, you must identify the species, explain the biological or environmental trigger, and detail the adaptive advantage. ETS scores responses on a 0–4 rubric (dual-scored 0–30) across Delivery, Language Use, and Topic Development. Successful answers hit 150–170 words, use clear signposting, and synthesize cause, process, and outcome without personal opinion.
On the January 21, 2026 TOEFL update, ETS retained the 4-task Speaking section but integrated updated STEM and ecological contexts into Task 4. You will listen to a 90–120 second lecture, take 20 seconds to prepare, and speak for exactly 60 seconds. The audio covers a scientific concept, followed by two concrete examples. Your job is not to transcribe—it’s to synthesize.

Each response targets the same prompt: "Summarize the lecture on Arctic tern migration, explaining the biological mechanism and evolutionary advantage." Word counts are calibrated for natural pacing at 2.5 words/second.
The professor explains how the Arctic tern executes the longest annual migration of any bird, traveling roughly 70,000 kilometers between Arctic breeding grounds and Antarctic feeding zones. The biological trigger is photoperiodism: as daylight shortens in late summer, the tern’s pineal gland adjusts melatonin levels, which cascades into hormonal shifts that initiate fat storage and restlessness. Once airborne, the birds exploit two major wind corridors. They follow the North Atlantic gyre southward, then ride the circumpolar current north. This dual-route strategy minimizes energy expenditure. Evolutionarily, the migration grants the species access to nearly continuous summer daylight at both poles, which extends foraging time, accelerates chick development, and ultimately maximizes reproductive output across generations.

The lecture discusses the Arctic tern’s extreme migration, which covers about 70,000 kilometers every year. The main trigger is changes in daylight. When days get shorter, the bird’s brain releases hormones that tell it to store fat and start moving. During the journey, the terns use predictable wind patterns. They fly with the North Atlantic winds going south, and then use another wind system to return north. This helps them save a lot of energy. From an evolutionary perspective, this migration is highly beneficial because it allows the birds to live in two polar summers. They can find food almost constantly, which means their chicks grow faster and more of them survive each year.

So the professor talks about the Arctic tern. It migrates from the Arctic to the Antarctic every year, which is like 70,000 kilometers. This happens because the days get shorter, and that changes the bird’s body. It makes them store fat and fly away. They follow the wind to save energy, going down with one wind and coming back with another. This is good for them because they get more daylight in both places. More daylight means they can find food longer, so the babies grow up quickly and more survive. Overall, the migration helps the species reproduce better.
Scoring Breakdown:

The Arctic tern bird flies very far. Maybe 70,000 kilometers. The lecture says it goes because of light. When days are short, the bird gets ready to leave. It uses wind when it flies. This helps it not get tired. The reason it does this is for food. More light means more food. Then the chicks grow fast. Many survive. This migration is important for the tern population. It helps them live longer and have more babies. That’s what the professor explained about animal movement.

ETS analyzed over 10,000 Task 4 responses from the 2026 pilot phase. 68% of test-takers scored below Level 3 because they prioritized transcription over synthesis. The multistage adaptive Speaking section means your Task 4 response directly influences whether you receive a harder or easier final task. Mastering the 60-second summary format now prevents score volatility. Practice with timed AI feedback to calibrate pacing, reduce filler words, and lock in academic collocations before test day.
