Although they were reluctant to provide comment to Peace Arch News, a couple of White Rock area㽶Ƶֱs newest residents are causing quite a spectacle on the waterfront for both locals and tourists.

For the last couple of weeks, a pair of grey whales have been spotted 㽶Ƶֱ almost daily 㽶Ƶֱ feeding off the shore of White Rock㽶Ƶֱs beach.

The whales were viewed by tourists most recently on Thursday, and have been seen within 100 metres of the White Rock Pier.

Department of Fisheries and Oceans Canada research scientist Thomas Doniol-Valcroze told PAN Thursday that it㽶Ƶֱs perfectly normal for grey whales to be close to White Rock at this time of the year.

㽶ƵֱThey㽶Ƶֱre a migratory species,㽶Ƶֱ Doniol-Valcroze said. 㽶ƵֱThe vast majority of the population migrates from down south, in Mexico, all the way along the shore to Alaska and even to Russia.㽶Ƶֱ

He said the whales make frequent stops, 㽶Ƶֱlike pit stops,㽶Ƶֱ to find food and refuel. Grey whales have been known to feed in one location for days, or even a few weeks, before carrying on in their journey.

He said that grey whales have a diverse diet, but they㽶Ƶֱre mostly interested in crustaceans.

㽶ƵֱSome of them feed on the bottom. The grey whales are known to search through the mud to find them,㽶Ƶֱ he said.

The whales near White Rock, he added, would likely be looking for 㽶Ƶֱsmall, shrimp-like organisms.㽶Ƶֱ

㽶ƵֱThey found a good spot because they㽶Ƶֱre staying there. There must be a good reason.㽶Ƶֱ

Doniol-Valcroze said there are an estimated 27,000 grey whales off the North Pacific coast, but not all travel the distance to Alaska.

He said about 250 whales, which scientists have called the 㽶ƵֱPacific Coast feeding group,㽶Ƶֱ will stay in B.C. waters, west of Vancouver Island, for the duration of the summer.

Recent news articles from American publications draw attention to the number of grey whales that have washed up on Pacific Coast beaches. According to a Washington Post article, nine grey whales have washed up in California in a little less than two months.

Doniol-Valcroze, who added that a grey whale washed up on the coast of B.C. in recent weeks, said it㽶Ƶֱs too early to tell if the deaths are signs of a major mortality event.

㽶ƵֱIt㽶Ƶֱs not a concern to find dead whales from large populations. We㽶Ƶֱre going to lose some every year. What is a concern with some of those recent deaths is a lot of the whales were showing signs of being emaciated. Maybe not having enough to feed on in recent weeks or months. That could be a concern.㽶Ƶֱ
