Linking killer whale survival and prey abundance: food limitation in the oceans

This study came out by John K. B. Ford, Graeme M. Ellis, Peter F. Olesiuk and Kenneth C. Balcomb, all highly esteemed whale scientists.

Here is an except:  Resident killer whales are primarily salmonid predators that show strong selectivity for Chinook salmon (Oncorhynchus tshawytscha), probably because of this species' comparatively large size, high lipid content, and year-round...

Orcas off B.C.’s coast love the taste of shark

But they’re wearing their teeth flat on the abrasive skin of the sleeper shark, study says

By Larry Pynn, Vancouver SunJanuary 17, 2011 Scientists know little about the offshore killer whales, identified off the coast in 1989, due to their nomadic movements.

A mysterious population of offshore killer whales in B.C. are specialists at killing sharks — to the detriment of their teeth...

BORN: Another new calf in the Southern Resident Killer Whales!

A new L Pod calf, initially spotted in Juan de Fuca Strait last week, is the first recorded calf for 20-year-old L82 said Ken Balcomb, executive director of The Center for Whale Research in Friday Harbor, Wa.

It is the second L Pod calf of the season, but L47..., the other mom, has not had any of her previous four calves survive,

"This one is doing well so far, so we hope this will break the pattern,"

San Juan Safaris

I did the 'Whale Plane' from Lake Union Seattle. Forty five minutes on a fantastic small sea plane, with wonderful views. Went on smaller boat from San Juan safaris with only 12 on board. We left early as we were all on board to give us the best chance of seeing the orcas.We roared off very fast, which was very exciting. The naturalist aboard was very friendly and...

This just out regarding Salmon (resident orcas mainstay of food). It is interesting enough that I am putting up on our blog, which is usually reserved for  crew to report on their tour experiences.

Here is the link.  It is only about a 2 minute piece - give a listen?  http://www.publicbroadcasting.net/kplu/news.newsmain/article/0/1/1690183...

NORTH BONNEVILLE, WA (N3) - Banner runs of salmon and steelhead are migrating up some Northwest rivers this summer. Not since dams were...

Each day as we cruise out of Friday Harbor, with hopes of seeing whales drifting about in our heads, I start the guests of with an introduction to the San Juan Islands and the all the wonders the islands offer. I often mention in this introduction that we as naturalists love questions. Not only do we have a passion to educate, we all have a passion to share the facts that YOU as a guest want to know. As an educator, I feel that people retain information better if it is something they...

Today was an exceptional day, amazing wildlife everywhere and beautiful weather! The animals seemed to get bigger and bigger as we continued our trip. We started by observing some harbor seals warming themselves on the rocks, these animals weigh about 300lbs as adults. Our next stop was the much larger Sea Lions that we spotted in Cattle pass. They have been hanging out in this area fishing for the past few days and it's been exciting each time to see them.  We were now on our way...

It has been a few days since we have seen L pod (or the Southern Residents in general)  and we can only assume that means they have gone off in search of food in the Pacific, but today we were in luck!  This  afternoon reports came in that they were headed towards San Juan Island. As we headed off for our afternoon trip we decided to go south around the tip of San Juan Island and over to false bay to greet them. Before we could get there we stumbled upon a stellar sea lion swimming...

We saw a minke whale on the west side of Waldron Island today!  Although there weren't any reports of orcas, we still managed to see a lot of marine wildlife.  We rarely see minke whales this many days in a row.  They are solitary travelers and can hold their breathe for long periods.  So when they come to the surface for air, you can't help but get excited.  Our guests had some spectacular views of the minke today.  We spent a while with the whale and then headed towards the Cactus...
