Have Blue Whales Stopped Singing? Paying Attention to Their Songs Could Benefit Humans, Too
Research published earlier in 2025 found that whales sing less when food is scarce. Using underwater microphones, or hydrophones, an interdisciplinary team of researchers recorded the songs of blue whales and humpback whales as they spent time in the Monterey Bay National Marine Sanctuary on their usual migration routes. The study began in 2015 during an intense marine heatwave, which greatly reduced the whales’ food sources. Over the course of the study, the singing of both blue and humpback whales was at its lowest point during the peak of that heat wave.
