Record number of Bigg's killer whales spotted in the Salish Sea

It's a big week for Bigg's whales.

A record number of the transient killer whales were counted off the coast of British Columbia and Washington state Thursday.

According to thePacific Whale Watch Association (PWAA), whale watchers counted 10 distinct groups of the animal between Campbell River and Puget Sound for a new single-day high of more than 70 whales.

"The number might sound unbelievable, but it's no April Fools' joke," saidPWWA executive director Erin Glessin a statement announcing the sightings.

Mark Malleson, researcher for the Center for Whale Research and longtime guide for Prince of Whales in Victoria,confirmed the number as a new Salish Sea record.

According to Malleson, there have been days in the past decade where 50, maybe 60, Bigg's were spotted, but he said in a statement that Thursday's tally was "astounding."

The largest group spotted, said PWAA, was near the northern San Juan Islands and had 18 whales.

Sam Murphy of Island Adventures Whale Watching in Anacortes, Wash.,was lucky enough to witness it and said in a statement that, at first, four whales appeared and then, suddenly, "out of nowhere, 14 more materialized."

"It was magical," said Murphy.

Bigg's killer whales are the mammal-eating cousin to the endangered southern resident killer whales, which feedon waning salmon stocks.

Unlike their struggling relatives, Bigg's whales hunt marine mammals and are thriving because of an abundance of seals and sea lions in the region,according to researchers.

Glesssaid the total count was 72 and told CBCthis time of year is known as the "spring surge" for Bigg's sightings because the Salish Sea is like a seal snack buffet right now.

"They have moved in. The dinner bell has been rung. Word is getting around this is the hot new restaurant in town," said Gless.

The abundance of whales in the water right now, she said, is important for recreational boaters to keep in mind when heading out to play.

"These whales are here so when you are out on the water be mindful," said Gless.

She said it is critical to slow your speed and be vigilant whenever you see a whale watching vessel as there are quite likely whales in the area.
