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.

, including here in Hudson Bay. And even though this is probably the biggest beluga population in the world, scientists are a bit concerned.“The disappearing ice is going to affect them,” Vergara said. “We don’t know how they’re going to react to shifts in water temperature, shifts in food availability, shifts in the availability of regular prey.”Beluga whales swim through the Churchill River, Monday, Aug. 5, 2024, near Churchill, Manitoba.

Arctic cod, a high-fat fish that is key in beluga diets, is diminishing, said beluga expert Pierre Richard of the Northern Studies Center in Churchill and author of three whale books. But he said it’s an open question on whether belugas can adapt.

In the Beaufort Sea, research shows that belugas aren’t as fat as they used to be, but scientists don’t know about those in Hudson Bay, Richard said. Another issue is that killer whales that hunt belugas are coming more often into the Hudson Bay and less sea ice means fewer places for belugas to hide, he and University of Washington marine mammal scientist Kristin Laidre said.how ammonia could be used in combination with diesel as a marine fuel.
