Orca babies, that is! This winter we’ve had three calves born to our resident pods of killer whales. Two of the calves were born to J-Pod, the group that spends the most time around the San Juan Islands. The third baby belongs to L-Pod, the largest of our three pods of Southern Resident Killer Whales (SRKW).

Every new addition to our local pods is awesome news, because this population has been in trouble. The Southern Residents were listed under the Endangered Species Act back in 2005, but the population has continued to decline and there haven’t been any surviving calves born since 2012. So these three blushing babies (whale calves are born with a pink hue on their white parts) are most welcome.

The first calf to show up, J50, was just the Christmas present all our local orca fans were wishing for. This little one was born right around December 25th in the protected waters of East Sound. (You might remember Teri’s post reporting a sighting of the new calf during her Christmas cruise.) Making the present even better for JPod is that J50 (it’s a tough ocean out there, so baby orcas aren’t given their human nicknames until they survive a full winter) is a little girl, and this population needs all the future mommies it can get. J50’s mom is Slick (J16), who is over 40 years old!

There’s definite girl power in orca pods, as our residents live in matriarchal societies. Each pod is made up of smaller matrilineal lines led by a mother, grandmother or, as is the case with Jpod, by a great-grandmother. In J-pod, that’s J2, Granny, the best-known wild whale in the world, who researchers believe is around 104 years old!

The next baby in this recent boom is J51, born early February somewhere in the Straight of Juan de Fuca to 36-year-old Shachi, aka J19. As of this writing, J51 hasn’t rolled over yet to give researchers a look at its belly to be able to tell if it’s a boy or girl.

And just this week, on February 23, a new L-pod calf, L121, was seen off the Oregon coast happily swimming alongside its mom, 20-year-old Calypso (L94).

Three babies within just a few months is a huge deal here. The whales only give birth about once every five years, and out of our current population of 80 (a near record low), there are only a few reproductive-age males, and several of our reproductive-age females had not been having calves. Late in 2014, disaster struck the Southern Residents when Rhapsody, J32, a 20-year-old female just coming into her prime breeding years, died from a problem pregnancy.

In addition to the new calves for the Southern Residents, there has also been a baby spotted with one of the Transient pods of orcas that frequents our local waters. Though it’s tough for casual observers to tell the Residents and Transients apart—they’re all huge black-and-white members of the dolphin family—there are actually marked differences between the two types of orcas.

My husband took this lucky “spy hop” shot from our boat last year when we were drifting off Henry Island and the orcas swam up to check us out.

Resident orcas live in much larger groups than Transients—if you’re out on the water and see more than four or five orcas together, you’re almost certainly seeing Residents, who sometimes even form Superpods when J, K and L all get together to socialize. A small group of whales seen around the San Juans could also just be one family of Residents swimming together away from the rest of the pod, but if you see them acting very stealthy then it’s more likely you’re seeing Transients.

The reason the two types of killer whales act and group differently is because they’ve evolved remarkably different cultures. Transients travel in small, stealthy groups because they’re always trying to sneak up on marine mammals like seals. Usually the only time you’ll ever see Transients leaping out of the water and doing celebratory fin slaps and tail lobs is after they’ve had a successful hunt. Fortunately for them, if there’s one animal we have plenty of in the Salish Sea it’s harbor seals, so the Transients have pretty easy hunting.

Our Residents are not so lucky. They’ve evolved to eat fish, and in particular, to specialize in hunting big, fat Chinook salmon. The salmon aren’t as smart as seals, so the Residents are able to talk to each other a lot more (each pod even has its own dialect of orca language). They can also splash around more at the surface because they don’t have to worry about the fish jumping out of the water and climbing up on rocks like seals can. So salmon are easier to hunt, but that’s just the good news. The bad news is that Chinook populations have their own troubles—so much so that they’re also listed as endangered. Each one of our Resident orcas needs to catch between 100-300 pounds of sushi a day just to stay healthy, and every year there are less fish around.

Challenges in finding food is likely the main reason our Southern Resident Killer Whale population hasn’t bounced back. Scientists believe there used to be around 200 Resident orcas frequenting the Salish Sea, but that was before a bunch of them were kidnapped for aquariums. And before that, they were even hunted and considered nuisances known as Devil Fish.

So for our iconic and well-loved group of Resident orcas to suddenly jump in number from 77 to 80 is big news. Seeing wild orcas is one of the many reasons why living in the San Juan Islands is such a special privilege. We’ll all be pulling for these new babies to thrive, since they’re carrying the hope that we’ll continue to have the honor of sharing the Salish Sea with these beautiful and complex creatures for many years to come.
