Suddenly, five or six surround the surfers’ boards, diving from one side to emerge from the other. Beneath the surface, two small eyes and a big smile: every summer 55 000 Beluga whales migrate from Arctic waters to Hudson Bay, in Canada.
Away from the Seine, where a beluga whale went missing in early August north of Paristhis Canadian estuary allows these small white whales that travel in flocks to give birth in these relatively warmer and safer waters.
Beneath the somewhat cloudy surface, beluga whales amuse themselves with the presence of tourists who have come to Churchill watch them. This little town 800 inhabitants It is not easy to get to as it can only be reached by train or plane.
More than seven months of the year, from November to June, the entire bay is completely covered with ice. The place is ideal for them: it protects them from killer whales and the mouths are rich in food.
“Beluga is a sound-oriented species. For them, this is what vision is for us, ”explains a researcher from the Raincoast Conservation Fund. | Font: AFP
The youngest specimens are easy to distinguish because they are still gray compared to the whiteness of adults. Outwardly, it seems that they are always smiling.
But what is most surprising is their communication, which at times can be heard from the surface.
Hydrophone
Nicknamed “sea canaries” because of the approximately 50 vocalizations (whistling, clicking, ringing) they make, they are “sociable” animals with a “very complex communication system,” he says. Valeria Vergarawho has been studying them for years.
“Beluga is a sound-oriented species. For them, this is what vision is for us, ”explains a researcher from the Raincoast Conservation Fund.
Listening carefully to a hydrophone speaker, this 53-year-old scientist tries to decipher the many sounds coming from deep within. For the untrained ear, this is a set surprising and cacophonous.
“They use sound to communicate and also locate themselves to find their way, food,” adds the expert, who has learned to recognize the “contact calls” that mothers use to guide their young.
Newborns with a height of 1.80 m and a weight of 80 kg depend on their mother for two years. At adulthood, it is a mammal that usually develops in the icy waters around Greenland and north of Canadafrom Norway and from RussiaIt can reach a size of six meters and lives from 40 to 60 years.
The beluga population in Hudson’s Bay is the largest in the world. But shrinking glaciers due to climate change in an area that is warming three to four times faster than the rest of the planet is worrying researchers.
