Gaspar’s name was on the tip of everyone’s tongue last Monday when this female humpback appeared near the shores of Les Escoumins. Other rorqual species also made observers’ eyes light up: fin whales and feeding minke whales, not to mention well-known blue whales! Belugas have been increasingly congregating in the estuary area, while seals and harbour porpoises are also being added to the list of species chalked up.

Gaspar is back!

There are many stories surrounding Gaspar’s (H626) first visit to the estuary. “I was lucky enough to see her on Monday, June 15 from the Les Escoumins–Trois-Pistoles ferry dock,” shares one whale enthusiast. “More spectacular moments this Wednesday evening…” exclaims a naturalist and wildlife photographer who had the privilege of observing her. In early June, rumours were going around about Gaspar’s visit to Gaspé Bay, and a few days later, videos of her hallmark tail fluke betrayed her presence near Anticosti Island. Now she’s in the estuary, over 500 kilometres away!

Since she was first sighted in the estuary in 2006, Gaspar has returned every year except in 2008. Generally, whales return to the feeding grounds where their mothers took them the year they were born. However, Gaspar’s mother Helmet (H166) escorted her only as far as the gulf her first summer. Gaspar later made her own exploratory incursion into the estuary, and it would appear that she’s since made this territory her own! The following day, humpback whale H859 was spotted in the Saguenay–St. Lawrence Marine Park, much to the delight of marine mammal enthusiasts.

Fin whales Ti-Croche (Bp955), Piton (Bp942), Kashkan (Bp918) and Bp2826 were also seen in the Marine Park in recent days. With these whales either moving about or feeding at the surface, their observers were treated to a real show! Several feeding minke whales and belugas were also showing off their distinctive black backs, pink bellies, and white backs at various locations from Saint-Irénée to Les Escoumins.

Blue whales at the edge of the gulf

The largest of whales was spotted by an amateur cetologist conducting transects for the Mingan Island Cetacean Study (MICS) between Matane and Pointe-des-Monts. Not one, but three blue whales were observed, including the well-known female Jaw-Breaker. “It’s encouraging; I was really happy to see them,” he remarks. The Sept-Îles Education and Research Centre (CERSI) team also inaugurated its field season, but the weather wasn’t particularly cooperative: “It’s been raining here for over a week, so we only went out once, and we had very little action—just two grey seals. Hopefully, next week will be better!” A harbour seal was spotted at the mouth of the Sainte-Marguerite River in Gallix.

Belugas and minke whales were observed near Baie-Comeau. A tail fluke belonging to a humpback was even reported in Franquelin. The individual’s identity is still a mystery, however.

More rorquals in Gaspésie

“I went to Grande-Grave in Forillon National Park: three humpbacks and two minke whales passed very close to the wharf and disappeared as quickly as they had appeared! With the late afternoon light, it was magical!” marvels a local resident.

Another observer noted having also seen two or three minke whales near Cap-aux-Os a few days earlier (June 15). In the Gaspé Peninsula, as elsewhere in recent days, the weather has been less than ideal, hence the lull in observations.

Rain and wind don’t deter whales and seals from surfacing to breathe. In fact, it’s a vital function. The blowhole on the top of their head—essentially an oversized nostril—allows them to inhale air that then passes through their nasal passages, trachea and larynx before ultimately reaching their lungs. With each breath, whales renew nearly 90% of their air, unlike humans, for whom this figure varies between 10 and 15%!
