# PTE HIW #14: Humpback Whale Vocalization and...

Highlight Incorrect Words #14 - Level 2 - Feeds Reading + Listening

> You will hear a recording. Below is a transcription of the recording. Some words in the transcription differ from what the speaker(s) said. Please click on the words that are different.

Humpback whales sing most frequently where and when they breed. But researchers have found that whales can sing complex songs even when diving and searching, when it's neither the time nor the place for mating behavior. The study is published in the journal Plus One. Researchers tagged 10 humpback whales with suction cup sensors and tracked each mammal for a full day in an arctic waters during the fall, this time and place when whales feed rather than mate. While the sensors picked up background song near all of the whales, two individuals performed long, complex songs more suited to mating behavior. They even sang while on feeding lunges more than 100 meters below the surface. The fact that these whales can sing even under widely different water pressures may help us figure out how they produce their songs. And more important, the overlap in breeding and feeding activities proves humpback and other baleen whales are way more behaviorally flexible than we thought. Unlike some human singers, they are definitely not one hit wonders.

## Answer

- found -> discovered
- searching, -> foraging,
- mate. -> breed.
- sing -> vocalize

## Explanation

The recording differs from the transcript in 4 places: "found" should be "discovered"; "searching" should be "foraging"; "mate" should be "breed"; "sing" should be "vocalize".

## Hints

- Focus on the specific behaviors mentioned in the audio and when they occur.
- Pay attention to the researchers' observations about the whales' singing habits during feeding.
