Ocean brawlers: Whale watchers get unusual check out of orcas and humpbacks battling in Salish Sea

Users of the Pacific Whale Watch Affiliation (PWWA) caught a unusual check out of aggressive activity between two giants of the sea on Thursday, when a huge team of transient Bigg’s orcas squared off with a pair of humpback whales over the training course of a few hours.

Capt. Joe Zelwietro of Eagle Wing Tours noticed a group of about 15 killer whales being “unusually energetic” in the Juan de Fuca Strait, a stretch of the Salish Sea between Vancouver Island and Washington state, soon immediately after 11 a.m. PT, the PWWA mentioned. 

A several minutes later on, Capt. Jimmy Zakreski of B.C. Whale Excursions observed there have been two humpback whales in the middle of the group of orcas, the association mentioned.

“All-around these pieces, it is quite widespread for us to face orcas. It can be also very widespread for us to encounter humpbacks,” said PWWA executive director Erin Gless in an job interview.

“It is not pretty common for us to come upon them in the center of a brawl.”

All through the 3-hour face, which took place around 40 kilometres west of Victoria, observers say the mammals breached, slapped the drinking water with their tails and produced loud vocalizations right before they finally disappeared into the fog.

“I’m however seeking to wrap my head around it mainly because it was completely unbelievable,” said Mollie Naccarato, a captain and naturalist with Sooke Coastal Explorations on south Vancouver Island.

“At very first the orcas seemed to be chasing the humpbacks, but then when there was space in between them, the humpbacks would go again toward the orcas.” 

Gless states the orcas were witnessed circling the two humpbacks and at times nipped at their flippers and tails.

Territorial or predatory?

Bigg’s orcas feed on marine mammals these as seals, sea lions, and porpoises, but do at times hunt larger sized prey, she mentioned. Which is in distinction to the northern and southern resident orca groups, which feed mainly on fish.

“Orcas are the only normal predator that humpback whales have in this region,” Gless stated. “Even nevertheless humpback whales can get to be the size of a university bus, a team of quite skilled hunters can assault [them].”

Gless claims there was some discussion amid whale watchers who witnessed Thursday’s conversation as to regardless of whether the behaviour was territorial or predatory.

Some consider the killer whales had been acting surprisingly because they were being irritated about the humpbacks being on their turf, when others believed the team of orcas showed a several of the typical logos of a team searching solution.

“We saw some of that splashing about … getting on top rated of the again of the humpbacks as they had been striving to breathe,” she said. 

The humpback whales involved have been determined as BCX1948, known as Reaper, and BCY1000, known as Hydra.

Reaper is at minimum four a long time old and has been matched to winter breeding grounds off Jalisco, Mexico Hydra, an adult female, has been matched to breeding grounds in Maui, Hawaii, wherever she’s presented delivery to at least three calves.

Gless suggests nobody saw how the conflict was solved since it was notably foggy when both sides swam off. A number of teams will be again out on the water Friday, making an attempt to spot the two humpbacks to see if they produced it out alive.

Gless claims the orcas’ behaviour was not totally out of the ordinary but it truly is an experience whale watchers have seldom witnessed, in particular not up near. 

“We genuinely received to see some thing impressive,” she explained.

But it could come to be more frequent as the populations of both species continue to grow, she included.
