Listen to Baby Humpback Whales Whisper to Their Mothers

Humpback whale babies don’t scream for their mothers’ attention — they whisper.

Researchers who listened in on communications between humpback whale mothers and their calves believe they recorded what amounts to a whale whisper. Using detachable acoustic tags, the researchers followed eight calves and two mothers for 48 hours each as they swam near their breeding grounds off Australia’s coast, and say that this is the first time such vocalizations have been recorded in this manner.
