'Residents', the Salmon Specialists
'Residents' should really be called 'loud-mouthed salmon-hungry swim-with-their-mother' killer whales. They might seem like residents when they show up to their favorite fishing hole at the same time every year, but some pods of so-called 'residents' travel 1800km! Like our AF5, AF22, and AG pods that spend most of their time in Southeast Alaska, but are seen frequently in Prince William Sound, Kenai Fjords, and Kodiak! Also the L pod in the San Juan Islands makes regular winter trips to the coast of California.
These salmon specialists LOVE salmon, and it makes up a huge proportion of their diet. In our study area in the Gulf of Alaska, our research shows that Chum, Chinook, and Coho salmon are all very important for these large and calorically expensive whales. We have found they they consume a small amount of Pacific Halibut, Arrowtooth Flounder, and a very small amount of Sockeye Salmon. Is it a surprise to anyone that they don't seem to like Pinks very much?
Residents do in fact swim with their mother their entire lives, so when you see a big bull male, he is not the leader of the pack... He is a giant Momma's Boy! He will mate outside the pod when many animals get together temporarily, then its back to live with Mom.
Residents are very chatty, their families/pods can be identified by their calls, check out our acoustics page!

"Transients,' or Bigg's killer whales, are the mammal specialists, and while they often have a huge range compared with residents, they have their favorite hunting spots also. They have home ranges, just a bit bigger. In fact, we have some very 'local' transients.
​
They love harbor seals and porpoise, which have a lot of blubber and don't put up much of a fight. Some 'transients' will take sea lions, fur seals, or even larger whales, but this is dangerous work and requires some specialized skills... it doesn't happen overnight!
Its hard to think of Alaska and not think of Humpback Whales!
​
We at NGOS work together with colleagues at NOAA and the University of Alaska to help monitor the humpbacks of the Gulf of Alaska.
​
Long migrations to Alaska to feed, Hawaii to breed, our humpbacks are travellers! Over 8,000 km round trip! Happywhale.com has helped to match some very long migrations.
​
In recent years, the humpbacks have not had very many calves with them (we've heard the same from Hawaii). This worries us that there may not be enough Herring, Sandlance, Krill, or other prey for these gentle giants.
