Fin whales were well represented this week, as were belugas and seals. When they surface, some of these individuals have been showing familiar backs or dorsal fins. Spouts of great whales echo across the tidal flats, their shiny backs glistening in the sun and their fins fluttering as they search of food.
Zipper is back!
This week’s stars include Zipper, a female fin whale known since 1994. She was spotted between Les Bergeronnes and Les Escoumins. Easily recognizable by the scar on her right flank, her presence marks a return eagerly awaited by whale enthusiasts. This is not the only fin whale present in the estuary, as others have also been reported. “Between Baie-Comeau and Franquelin, two fin whales have been surface feeding near the shore while two others are heading to another site.”
A blue whale appeared to be passing through Les Escoumins on April 10. A cetacean enthusiast describes her sighting: “Two large spouts toward Les Escoumins, at least one blue whale, and another whale that seemed to be moving at a good clip. We hesitated between a fin whale and a blue whale. It may well remain a mystery.” Perhaps it was the ? Last summer, a fin whale with characteristics reminiscent of a blue whale was a source of confusion with regard to its identification. After establishing a match with an individual photographed in 2012 and 2024, and thanks to a biopsy performed on the individual in 2012, researcher Julien Delarue and the Mingan Island Cetacean Study (MICS) were able to crack the mystery and confirm its hybrid status. The individual was also seen again this winter, so those observers who are always questioning everything may be right!
Sightings have also increased at other points along the river. In Essipit, a fin whale was seen moving west, and a little later, a small group of belugas – sometimes solo, sometimes in pairs – was observed heading westward, taking advantage of the incoming tide. For one traveller, seeing these belugas for the first time was an unforgettable experience.
Habits and surprises
Seals also seem to be returning to their usual ways, with harbour seals back on their favourite rocks, offering interesting scenes for patient observers. “The harbour seals seem to be returning to their usual resting spot. I can watch them for hours in the hope of capturing precious moments of their lives.” In La Malbaie, a lone seal was spotted on a rock near the Pointe-au-Pic wharf.
Lastly, a few belugas were observed in the Bas-Saint-Laurent region. One of them, an adult, had an unusual hump on its back. A resident commented on his observation: “Last Friday, April 11, a few belugas were roaming around the Rivière-Ouelle wharf, which is a typical scene between mid-April and mid-May. One of the animals, however, caught my attention! It was an adult with an enormous hump on its upper back, which gave the impression that it was coming up for air in two bursts!” According to the Group for Research and Education on Marine Mammals, it is most likely either Pascolio or Néo, two well-known individuals that can be recognized by their curved backs. Photos have been submitted for analysis.
Thanks to all our collaborators!
