ON HUDSON BAY (AP) 鈥� Playful large white beluga whales bring joy and healing to Hudson Bay. Their happy chirps leap out in an environment and economy threatened by the melting sea ice, starving polar bears and .
Loud and curious belugas swarm boats here, clicking, nudging and frolicking. At any given summer moment on the Churchill River that flows into the Hudson Bay, as many as 4,000 belugas can be up and down the waterway, surrounding vessels of all sizes. That makes it hard to find a place where you don't see them, said whale biologist Valeria Vergara, senior scientist at the Raincoast Conservation Foundation. It's in their nature.
鈥淭he social butterflies of the whale world... You can see it in Churchill,鈥� Vergara said.
The town of Churchill is counting on that to continue. The mostly Indigenous community, by , faces the prospect of a dwindling number of bears because of climate change. So it is counting on another white beast, the beluga, to come to the rescue and entice summer tourists 鈥� if the sea mammals can also survive the changes to this gateway to the Arctic.
There's something healing about belugas. Just ask Erin Greene.
Greene was attacked by a polar bear in 2013. She doesn't like to go into details about the attack, but Mayor Mike Spence said she was thrashed by a bear which had her in its jaws. A neighbor hit the bear with a shovel, and a third person used a truck to scare off the bear, which was later found and killed. Years later, Greene said contact with the sociable whales helped pull her out of post traumatic stress disorder. Now she goes out in the water with them, on a paddleboard, and sings to and with the whales. She also rents paddleboards to tourists, so they can do the same.
Greene, who isn't native to Churchill but came to work in the tourism industry, tried yoga, which eventually led to paddleboarding in Hawaii. It made her feel a little better, so she thought she'd bring it back to Churchill where there isn't just water, but belugas. And that helped her heal, 鈥渕oving through the various stages of dealing with trauma," she said.
But it's not just her, she said. When she brings her customers into the water, inches from the whales, they also feel better.
鈥淚've never seen an animal except for maybe puppies bring that amount and capacity of joy to people,鈥� Greene said. 鈥淓verybody's smiling when they get off the water... Everybody's just experiencing joy. And it's the whales that provide that.鈥�
鈥淲ith the beluga whales, I think it's quite a different connection than with any other animal because the whales are truly choosing to socialize with you. They want to play,鈥� Greene said. 鈥淭hat's really what sets them apart from other animals. They're so gentle. They have no desire to hurt the human.鈥�
It doesn't hurt that the whales have gotten to know Greene. Vergara has no doubt that they know her.
Greene sings to the whales, including 鈥淵ellow Submarine鈥� by the Beatles. She also sings the Will Ferrell Eurovision movie song "Husavik (My Hometown)" with the lyric, 鈥渨here the whales can live 鈥榗ause they鈥檙e gentle people.鈥�
That lyric is close to reality, whale expert Vergara said.
鈥淭hey really have traits that are so similar to human culture, so we can really empathize with them," Vergara said. "They form communities and networks. They cooperate and help raise each other鈥檚 young. They鈥檙e unbelievably vocal. They鈥檙e probably one of the most acoustically active or vocal mammals, along with humans, on Earth.鈥�
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鈥� calls 鈥測ou really don't think, 鈥極h, I鈥檓 hearing singing.' You think 鈥業鈥檓 in a jungle full of birds'.鈥�
It's a cacophony of clicks and whistles. But it's not random, it's like being dropped into a noisy festival, Vergara said.
鈥淵ou can't help but wonder what is it that they are communicating with each other,鈥� she said. 鈥淭hey absolutely rely on sound to maintain these very complex societies.鈥�
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 to each other have calls or names that are similar, sort of like a last name, she said.
Belugas get the nickname 鈥渃anary of the sea鈥� 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.
鈥淭he disappearing ice is going to affect them,鈥� Vergara said. 鈥淲e 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."
The change in ice is part of an overall altering of the base of the food chain: plankton. When those tiny creatures change it means 鈥渁 whole shift in the prey base of belugas,鈥� Vergara said.
Arctic cod, a high-fat fish, which 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 issues 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.
鈥淲hether belugas in the Hudson Bay are suffering from these ecosystem changes is not clear at all,鈥� Richard said.
Beluga whales, as a species aren't on an although an There are as many as 200,000 belugas worldwide and the International Union for Conservation of Nature that creates a global endangered list calls them a species of 鈥渓east concern,鈥� so Vergara said she often gets asked why not concentrate on animals in more imminent danger.
鈥淚 would say that the threat to animal cultures can happen much quicker than the extinction of an entire species,鈥� Vergara said. And if subpopulations of belugas are wiped out, their cultures disappear too.
鈥淚t's like losing a human language or a human culture,鈥� Vergara said. 鈥淲e should care.鈥�
