This week’s stars of the show were seals! Whether in Gaspé Bay, off the coast of Les Bergeronnes, or near the mouth of the Sainte-Marguerite River, these pinnipeds have been delighting observers with their unusual behaviour and curious gazes. With the holidays right around the corner, it’s the perfect time to get outside and enjoy some fantastic marine mammal sightings!

Pinnipeds in numbers

“It was truly a glorious, unforgettable day,” shares a naturalist and wildlife photographer from the Haute Côte-Nord region, his voice filled with emotion. “And… the biggest surprise of the day: two enormous, compact herds very close to each other, totalling at least 1,500 to 2,000 harp seals! “I’ve never seen so many in our area since I’ve been here.” It’s common to see harp seals swimming on their backs, their noses gracefully pointing skyward. In fact, they are one of the only pinnipeds to exhibit this unique behaviour! Groups of this size are generally observed during migration, when individuals travel thousands of kilometres.

Harp seals frequent the St. Lawrence in winter, usually to give birth to their pups, moult, and breed on the ice. With its white fur and black spots, this pinniped is quite handsome, especially when accompanied by its young, commonly referred to as whitecoats. However, it is important, even crucial, to keep your distance from them, both for their safety and yours!

Alongside these impressive gatherings of seals, we’ve also gotten wind of belugas, harbour seals, and grey seals. Several types of seabirds, including gulls, have also been noted around the area, and a fin whale made an appearance nearby. A few days earlier, two minke whales were also spotted in the vicinity.

Ice and beaches

In Gaspé Bay, harbour seals have been resting on their usual rocks. A group of about fifteen individuals was observed on the nearby ice. On the north shore of the St. Lawrence, near Gallix, another wonderful encounter with pinnipeds was reported: “I was playing on the beach with my grandchildren when we saw at least four harbour seals. […] At one point, one of them, which seemed kind of curious, came quite close, watching us out of the corner of its eye, and I was able to capture a nice photo of it. It was gorgeous, the sea was calm, and there was a sublime sunset!” shared a clearly delighted resident of the village.

Where are all the blue whales?

“I haven’t had any cetaceans this week, but I’m looking forward to seeing some blue whales,” confides one enthusiast. “I’ll try to go whale watching more in the coming weeks, fingers crossed for the return of the blues!” announces another seasoned observer. For the past few years in the Baie-Comeau and Franquelin area, blue whales have been stealing the show during the cold winter months. Currently, scientists still know very little about the migration patterns of this species. It is therefore difficult to say whether these giants simply remain in the St. Lawrence after their feeding season, or if they briefly leave and then return. Let’s keep our eyes open for their powerful blows in the weeks to come!
