Whether it’s the hundred or so belugas passing through Cap-des-Rosiers, seal antics at Putep ‘t-awt, or the large rorquals spotted in the estuary and gulf, this week was marked by a spate of exceptional encounters with marine mammals!

“Raft of belugas” in the Gaspé

Off Cap-des-Rosiers, while conducting transects for the Mingan Island Cetacean Study (MICS), a cetologist made a remarkable observation. “I encountered the largest group of belugas I’ve ever seen in the gulf,” he describes. Once, however, on July 1, 2021, I observed a group of about a hundred off the coast of Matane.” He estimates the number at over a hundred individuals, split into small groups of about fifteen individuals en route toward the estuary. The captain also mentioned that there were no calves or juveniles in the group, just white adults. “Awesome, but at the same time very surprising!” This isn’t the only place where white whales have been spotted, as about fifteen belugas were swimming off Gallix, while other were reported from Pointe-des-Monts.

Despite all these observations, it is important to remember that, with an estimated population of 1,850 individuals, the St. Lawrence beluga is endangered.  Major factors identified as threats or limitations to the recovery of the population include contamination from chemical products; loss and degradation of habitat; reduction in prey abundance, availability and quality; as well as disturbance. Every observation is therefore precious!  Do you want to help protect them, but don’t know where to start? Here are five actions to help protect this endangered species!

But that’s not all! Large rorquals were also present in the Gaspé region, with four blue whales, three fin whales, and four humpbacks recorded. As for the latter, a mother-calf duo in Gaspé Bay was particularly impressive. One naturalist also noted the presence of  “the first tuna of the season leaping out of the water. There’s lots of life and incredible weather conditions!” Harbour and grey seals are also being regularly observed.

Playful seals

“For the past three weeks, we’ve been regularly observing harbour seals and all sorts of acrobatics in the water,” explains one biologist as he shares his observations with us from the Putep ‘t-awt site in the Lower St. Lawrence. It’s often a similar scene that plays out: Two individuals approach each other, press their snouts together, and begin their antics. “We saw flippers slapping the surface, porpoising, repeated jumps out of the water, cavorting…” Sometimes it seems to be about a fish, but not always. Is this some form of competition? Mating? Fighting? Hard to say! The individuals end up moving away from each other.

Offshore AC and braving the flies

After sailing around the Mingan sector, one woman reported sightings of porpoises, grey seals, and harbour seals. On the hottest days, she heads out to sea to cool off a bit! “Nature’s air conditioning,” she explains with a chuckle. The MICS team reports over 26 sightings of minke whales over the last week, as well as 9 fin whales.

In Godbout, one resident heads out to admire a whale despite the swarms of insects present this time of year. “I’m sitting in my living room and I look out the window toward the river. Surprise! Right there in front of my house is a large rorqual feeding on the surface, not far from shore. It’s drizzling and there are lots of small black flies, but I decide to go out anyway.”

Saguenay–St. Lawrence Marine Park

One whale enthusiast admires cetaceans from the Marine Mammal Interpretation Centre. She describes the scene poetically: “A spirited minke whale has been feeding in the fjord since morning, with numbers of large white belugas glistening in the background like pearls.”

The large rorquals in the area are mostly the same individuals that have been present for weeks now, but the arrival of humpback whale H859 a.k.a. Yvon (in French) has been noted. This individual has been observed every year since 2018! Additionally, GREMM’s research team identified the beluga Miss Frontenac during an outing on July 10. When GREMM first encountered this female in 2004, she had only just been born. In 2014, Miss Frontenac was observed with a newborn, confirming that she is a female.

These data were reported by our network of observers. They give an idea of the presence of whales and in no way represent the actual distribution of whales in the St. Lawrence. Just for fun!

Thanks to all our collaborators!

Special thanks go out to all our observers who share their love for marine mammals with us! Your encounters with cetaceans and pinnipeds are always a pleasure to read and discover.

On the water or from shore, it is your eyes that give life to this column.
