Bickel)Unlike humpback whales, the vocalizations from belugas aren’t songs with rhythm and a pattern, she said. When she puts her hydrophones in the water to record the whales’ calls “you really don’t think, ‘Oh, I’m hearing singing.’ You think ‘I’m in a jungle full of birds’.”

It’s a cacophony of clicks and whistles. But it’s not random, it’s like being dropped into a noisy festival, Vergara said.“You can’t help but wonder what is it that they are communicating with each other,” she said. “They absolutely rely on sound to maintain these very complex societies.”

Research has shown that individual belugas have a distinct call that they use in communication, much like a name, Vergara said. And it takes a couple years for young whales to learn their parents’ name and their own. But whales that are related or hang out together have calls or names that are similar, sort of like a last name, she said.

Belugas get the nickname “canary of the sea” because of their vocalization, but it also could apply like the canary in the coal mine, warning about an environment getting more dangerous, Vergara said.A sea bird dives down to look at fish off of Wolf Island, Ecuador in the Galapagos on Monday, June 10, 2024.
