❝ Spring is the time of year when birds are singing throughout the Northern Hemisphere. Far to the north, beneath the ice, another lesser-known concert season in the natural world is just coming to an end.
A University of Washington study has published the largest set of recordings for bowhead whales, to discover that these marine mammals have a surprisingly diverse, constantly shifting vocal repertoire.
❝ “If humpback whale song is like classical music, bowheads are jazz,” said lead author Kate Stafford, an oceanographer at the UW’s Applied Physics Laboratory. “The sound is more freeform. And when we looked through four winters of acoustic data, not only were there never any song types repeated between years, but each season had a new set of songs…”
“We were hoping when we put the hydrophone out that we might hear a few sounds,” Stafford said of the earlier study. “When we heard, it was astonishing: Bowhead whales were singing loudly, 24 hours a day, from November until April. And they were singing many, many different songs.”
