Colourful St. Lawrence

A few observers gathered at Cap de Bon-Désir and the Marine Environment Discovery Centre were treated to a big surprise last Sunday when Crinkle, a female blue whale, emerged from the waters of the St. Lawrence at this location. This regular visitor to the estuary made more than one person happy that morning! The passage of a large tuna at the same location was the icing on the cake on this eventful morning. The previous day, two other blue whales, including the well-known Chameau, also brought smiles to many faces when they were spotted between Tadoussac and Les Escoumins!

In the same area, a number of other marine mammals have been present in recent days: a fin whale and plenty of minke whales, not to mention numerous harbour porpoises and grey seals observed from shore and on the water. On August 19, the humpback whale Galaxy even spent some time playing in algaeon the water surface, a longtime marine mammal observer reported in amazement. Last week also marked the return of Irisept to the estuary, a humpback whale first identified in the gulf in 1997!

In Baie Sainte-Marguerite, belugas have been reported every day over the past week. “Between 20 and 50 individuals, depending on the day,” says a GREMM drone pilot on site for the Window on Belugas project. Sometimes accompanied by calves, the groups reportedly even ventured upstream as far as Île Saint-Louis! Another small group of about five belugas made it to Saint-Irénée, according to a resident of the région.

Gaspésie also saw its share of marine mammals this week! Early in the week, humpback whales were seen breaching in Gaspé Bay, much to the delight of observers! Fin whales, minke whales, harbour porpoises and Atlantic white-sided dolphins – occasionally accompanied by grey and harbour seals – were also seen frolicking in the area. On August 21, two minke whales were seen off Grande-Vallée while a little farther west, it was one humpback and four minke whales near Les Îlets and three minke whales off Matane that caught observers by surprise!

The same day, an avid kayaker encountered several harbour seals near Rivière-du-Loup. “I don’t think the sighting is anything special, it’s just rare that an observer passes through the area in a boat or a kayak!” he exclaims. Off the coast of Cacouna, a dozen or so belugas passed by, while a few grey seals were seen from the Rivière-du-Loup marina by an observer from the Marine Mammal Observation Network (MMON).

In the vicinity of Sept-Îles, two humpback whales were seen passing through early in the week, and a very special observation was made here by the Sept-Îles Education and Research Centre (CERSI):a white cross hydromedusa, a very rare species in the region! Near the shores of Franquelin, it’s minke whales, seals and harbour porpoises that are being talked about, points out one resident of the region.

Whether black, white, grey or even blue, we never grow tired of admiring these marine mammals from one end of the St. Lawrence to the other!
