Blue Whales Spotted Close to Sonoma Coast

July 12, 2012

Blue whales, the world's largest animal, are being seen off the Sonoma Coast in greater numbers this year as they feed on an abundance of krill, the small shrimp-like crustaceans that populate the ocean.

"It is an extraordinary whale," said Sarah Allen, a marine biologist with the National Park Service. "Their backs go on forever and then there is this little dorsal fin, and the blow that is 10 feet tall."

While blue whales swim along the California coast every year, this year the krill is unusually close to shore, bringing beachgoers an occasional and rare viewing opportunity.

"I have never seen them so close. There were a couple that were a couple hundred yards offshore," said Larry Tiller, a retired Healdsburg organic farmer and whale-watching docent for Stewards of the Redwoods.

Tiller was at the Bodega Headlands on Wednesday, which has been his preferred whale-watching perch for the past decade. Seated in a canvas chair, binoculars around his neck and metallic whale pins in his hat, he shows pictures of the giant whales taken during the past two weeks.

"This whale is 70 feet long, it was two miles out," Tiller said. "That was 10 days ago, but they are still out there."

Two blue whales have also been reported during a recent 10-day period just off Point Reyes Beach South in the Point Reyes National Seashore.

"It is a rarity, but there have been a few sightings," said John Dell'Osso, a Point Reyes ranger. "The fact is we have seen a couple (of blue whales) a couple of times, but it is hit and miss. It is not like the migrations of the gray whales; we can almost set our watches by them."

The blue whales are 75 to 80 feet long, although a century ago there were reports of whales 100 feet long before they were hunted to the point of extinction by whalers.

Once they numbered 150,000 to 200,000, but now they are on the endangered species list. There are now an estimated 5,300 left. The majority, an estimated 3,300, are in the North Pacific Ocean.

This year, the reports of sightings close to shore have largely been in the Monterey Bay area, but the blue whales are also being seen in numbers off the Sonoma County coast.

In July, the blue whales start to arrive in the Gulf of the Farallons, Point Reyes and along the Sonoma Coast to feed, said Bill Sydeman of Petaluma, president of the Farallon Institute for Ecological Research.

"They will still be a few miles offshore, but they are so big that they are pretty obvious when they show up," Sydeman said.

A boat is still the best way to see the whales.

"We are seeing whales every day, but most of the time you are seeing a spout in distance," said Chris Lawson, a Bodega Bay commercial fisherman.

"There is a lot of krill around. You can get close at times -- you are not supposed to be within 1,000 feet, but when you are fishing sometimes it is unavoidable," he said. "I have been looking at them for 40 years and it is impressive."
