In 2019 Terry (aka “the amphibiographer”) got a camera that can shoot 4K video. But in 2019 our 2008 computer was not fast enough to play the clips. This meant that we couldn’t actually review video or audio of the whales that Terry recorded. Further down the line we couldn’t coordinate it with my hydrophone recordings. So in 2021 we finally bought a 2019 computer that could actually play the recordings we’d made. While listening to audio files of singing whales that I had recorded in October 2019 I heard grunts, growls, belches and squeaks that didn’t sound like a song. Are these these whales practising whale solfège? are they enjoying a good meal? or are they talking? What a find! I hope you enjoy the underwater conversation as much as we did.

August #1 2022 – How do Whales Nurse Their Babies?
More Moms with calves are showing up here in the Salish Sea this season – 6 pairs sighted so far. Judging by their playful acrobatics and assertive blows the young ones are thriving. The mothers seem to be in good shape as well considering they lose 1/3 of their body weight during the >10,000km (6,000 mile) round trip migrations to Mexico, Central America or Hawaii and back. Add in the previous 4 months of nursing her hungry baby and it’s no surprise that a mother whale’s prime directive once she reaches the feeding waters is to feed.
“It’s Big Mama” “And she’s got a calf!” Terry is jubilant. Big Mama is one of the whales we have met several times during the years we’ve been on the water. She is a prolific mother and veteran of the humpback comeback to the Salish Sea. Big Mama was the first whale to return to these waters in 1997. Since then she has brought each of her new calves back with her.
Big Mama and her new baby are accompanied by another adult whale. We couldn’t tell who it was because we couldn’t see the whale’s flukes or whether (s)he was female or male. If the companion whale migrated together with Big Mama and her calf from their southern mating/birthing area then this whale is probably a male who is interested in Big Mama as a potential mate. This “escort” can be an asset to Big Mama and her calf if a pod of killer whales attempts an attack on the young one as he will protect the calf with Big Mama. However, he can also be a nuisance if he attempts to mate with her and interferes with nursing.
Mother humpback whales nurse their babies for the first year even though the baby is already learning to fish as soon as she reaches the feeding area. The baby thrives on mother’s rich milk, which is between 45-60% fat How do whales (and dolphins) nurse in their underwater environment? Terrestrial mammals like humans have nipples which are exposed and easy to suckle. But the mammary glands of cetaceans (whales and dolphins) are concealed inside 2 slits on either side of their genital slit low on the abdomen. The nipples are inverted inside these mammary slits. A whale calf must dive underneath the mother and nudge the mammary slits with her rostrum to release the nipple from the slit. Whale calves might be able to roll their tongues into a tube shape and press their rolled tongue around the nipple to channel milk. The mother could then squirt milk into the calf’s mouth using muscles around her mammary glands. Because of the high fat content the consistency of Mom’s milk is thick and doesn’t easily dissolve in water if some leaks out.
Mom and calf stay in close physical contact in the first months of the baby’s life. So much of what transpires between moms and babies is speculation because it happens underwater out of our visual range. Their vocal communication also happens outside of our human hearing range. Mother and baby communicate through touch and very quiet low frequency grunts, barks and groans. They “whisper” so their sounds don’t attract killer whales. Because these “whispers” are so quiet Jude can only pick up a signal on her hydrophone within about 200m of the whales. However, since the whale whispers are too low for humans to hear it’s impossible in realtime to know whether any whale conversations are actually occurring. This can be very frustrating! It is only after recording in the vicinity of whales and afterwards importing the recordings into a software program called a spectograph which translates the sound waves into a visual representation that we can see whether we recorded something. It’s also possible to speed up the slow low frequency sound waves 2 or 3 times within the program so they can be heard in our human hearing range. Unfortunately there is no room in Blue P’s small cockpit for any more audiovisual or computer equipment and no budget for expensive hardware and software. All this has to be done later on our home system.
We learn that the whales are communicating all the time, which is obvious with any amount of time observing their interactions. In the plankton filled waters of the summer Salish Sea it is vibration and sound that carry myriad whale messages through the water. Once on the feeding grounds Big Mama and her calf may associate with various other whales through the season and even during one day. We watch them form a group, separate for a while and come back together obviously communicating with each other. Since all Big Mama’s children return to their mother’s feeding area some of these whale companions may be the new calf’s older brothers and sisters. So many intriguing questions…….
August #2 2022 – Surprise!
Terry and I have more than a nodding – pun intended – acquaintance with sleeping whales. In fact sleeping is what whales seem to enjoy most when in close proximity to Blue Parrot, our 50 year old sailboat. So when we encountered 2 humpback whales peacefully snoozing side by side in mid Sutil Channel Terry and I prepared to settle in for an afternoon nap. In fact Terry was just about to put his camera away for a while when this happened.
Which proves once again that understanding the motivations and behaviours of whales is a mysterious journey indeed.

July 2022 #3 – Bubble Feeding!
“T-Rex is bubble feeding off Wilby Shoals” the voice of whale watching guide ‘Supernova’ sings cheerily over SV Blue Parrot’s VHF radio.
“Let’s go!” I turn Blue P 90°W. We’ve been floating between Quadra and Cortes Islands scanning for marine mammals.
“It’ll take us half an hour to get there. She’ll probably have stopped by then.” Terry sighs .”it would be amazing to see lunge feeding again”
“YES!” I am juiced. We’ve only seen humpback whales lunge feeding once before and that was 4 years ago in 2018 – an unforgettable experience. Here is the link to that Blog:
https://welcomingwhales.com/2018/10/24/october-2018-humpbacks-lounge-feeding/
During the half hour it takes to get there at our extreme cruising speed of 4.85 knots we try to pinpoint the exact location of the whale. Whales are big but the ocean is bigger and they easily disappear from view. “There’s a circle of boats about 200m off the point. 3 look like whale watching boats” Hawk-eye Terry reports from the bow.
“I see them – on our way” If you can’t find whales in their feeding areas during the summer it’s a good bet that somebody else has. Boats that have been lingering in one place for a while without obvious fishing gear are probably with a whale. And people fishing forget to fish when there’s a lunge feeding whale nearby!
“I see the whales! 2 just came up in the middle of those boats” I slow to an even slower crawl and inch up to the scene. “Woah!” “Right beside the Boat!” They are less than 30 meters away, in close to the shore. Wilby shoals has depths varying from a few feet to hundreds of feet. Currently Blue P’s depth sounder is reading 18 feet!. “I’ve got to move out from the shore” Jude tells Terry. The whales move too – right past us around all the boats. In the time it takes us to move 30 meters they have covered 230. We wait. 20 minutes later………
“They’re coming back this way. They may be doing a circuit”. Terry shouts. I drop the hydrophone to record any feeding burps and belches.
“They’re making that sound!” “the whining sound that herds the fish-Uhrrrrrrrrrr? I try to imitate them. “I hear the bubbles………. Now they’re coming up! Phshshsh—–BUBUBUBUBUBUBUB” It’s a fairly pitiful imitation but with the hydrophone I can hear what the whales are doing underwater and predict when they will come up. Terry gets ready with the camera but I can’t predict where they will come up. He watches the sea gulls circle and hones in when they drop towards the water just as the whales break the surface. Focusing the camera on the exact spot where Terry deduces the whales will surface is a finely tuned art, experience and a large lump of luck.
In order to record a decent signal with the hydrophone we have to be within 200m of the whales. It’s difficult with all the boats starting and stopping their motors to keep up with the whales. But we can’t begrudge anyone this awesome experience. Everyone out here is just as thrilled as we are. And there are times when the whales are close enough for a clear recording. I am over the moon “I’ve waited 7 years to record bubble feeding”. In fact both of us are over the moon. We linger longer with our lunge feeding friends as the other boats leave, the sun sets and the moon rises. Ah…this is the magic time for the best video and audio recordings. We’ll travel back by moonlight – and our running lights of course.
October 2020 Halloween Reveries with Whales
These are the sounds we were hearing on Halloween night. Terry and I anchored off Savary Island in our little old sailboat Blue Parrot. A lovely end-of-October eve on the Salish Sea filled our senses. I dropped my 2 hydrophones over opposite sides of the boat about 4 metres deep into 8 metres of water. We were watching the full moon rise through ribbons of cloud over the mainland mountains. Mars rose orange in the East. Brilliant Jupiter appeared over Vancouver Island in the South with smaller, dimmer Saturn a little further Southeast. Silver moonlight lit the sky. Below, a calm silky ocean shimmered, where the occasional belch of a seal or cry of a gull drifted across the water. Moonight revealed the mainland contours on one side of the Strait and Vancouver Island on the other as far as we could see. Blooms of neon purple, green, red, indigo, yellow and white flowered over both shores chased by muted boombiddy-booms as adults and children around the Salish Sea gathered to enjoy the Halloween fireworks displays.
CLICK HERE TO LISTEN to this whale who was quite far away – probably 6 – 8 km. You can hear the sea splashing against the hull. The odd creaks and knocks are the boat rudder knocking and the crackles are shrimp talking on the bottom under the boat! One whale is singing all the notes – the very high squeaks and the low growls. He is practising his song for performing in Mexico or Hawaii. The song becomes more complex and developed in December before the whales leave on their southern migration.
It was Magic – perfect for a Halloween reverie accompanied by the haunting music coming through from the hydrophones. was this music the eerie wails of long departed souls? or aliens trying to communicate with receptive earthlings? No. The ghoulish notes in my headphones were the eerie wails of eerie WHALES – Whales who are very much alive on planet Earth right now. This is the music of humpback whales you are hearing. They’re practising their song here in the Salish Sea of BC before they begin their long migration to Mexico or Hawaii or even Japan. Once they have perfected their song, which slowly changes every year, they will perform it in the warm waters of their southern destinations.
No human knows why humpback whales sing or what the whales are singing about. Only the males sing and a singing male will attract other males who will often join in the song. In the 5 years we’ve been listening underwater for vocalizing humpback whales in the Salish Sea, the end of October and beginning of November are the only times we’ve heard any vocalizing at all. It’s another whale mystery that, along with so many whale mysteries, only adds to the awe that 2 tiny, curious humans feel when in the presence of these majestic beings.
Undoubtedly whale biologists feel it too, even while they conduct precise, tightly structured investigations and analyze the data. Whales are so much like us. Mothers feed, care for, teach and protect their babies. Whales often hunt and feed together with every whale having a prescribed job. They socialize and play with friends. Male Humpbacks sing and compose complicated songs. Whales from different areas have different languages, cultures and food preferences. They communicate vocally and with body language. But here is where we begin to differ. Aside from the obvious differences of size and body shape whales and humans have evolved very different physiologies in order to thrive on land or in the sea. We both have 2 eyes and 2 ears but what whales see and hear both underwater and above the water is very different from what humans see and hear. We humans do not have nostrils on top of our heads or mouths that gape open to our bellies while consuming more than 1 ton of fish per day.
Here is the biggest mystery of all in my humble opinion: Whales and dolphins are conscious breathers. They have to be awake in order to breathe. But, like every other mammal, they must sleep and dream. So they have evolved a clever work-around to allow them to sleep and breathe simultaneously. All dolphins and whales sleep with only 1/2 of their brain at a time. One hemisphere is off in dreamland while the other is monitoring the immediate environment and initiating breathing in realtime. Have you ever woken in the middle of the night and hovered in that half asleep/half awake horizon where dream characters populate your consciousness but you are also aware that you are in bed? or that the click you are hearing is your digital clock? or that you might have to pee? Is that how whales experience their sleeptime? I wonder what kind of consciousness that produces in whales?
And here is the real kicker. Humans have been learning about our planet from other animals and plants forever. We also use their special gifts to help us thrive in the environments we share. We use a dog’s sense of smell and hearing to help us hunt. We use the hawk’s eyes to scan the landscape. We tune in to the alarms of birds to notify us of predators in the forest. Plants, trees and fungi transform minerals and vitamins in soil and water into compounds that our cells can use to keep us healthy.
So why sit here in front of your screen googling for information on the internet when you can be outside letting your dog take you for a walk through a park or forest? Have you sat with your cat on the porch or balcony or slightly opened window of an apartment? Can you observe what she’s observing? Lots of folks can watch flowers, or fish, or listen to birds for hours. Try it. The world you’ll discover is the world that goes on around us 24/7, mostly unnoticed by humans.
As the dominant large animal species on Earth today we get lost in our own human stories. We root out ways we are different from each other while we are surrounded by beings who are more different from us than any human is from any other human. And what a cornucopia of differences there is – so many ways of perceiving the universe, more than we can ever know. So many stories to explore. Find someone to share your adventures and stories with. You will be constantly amazed as well as amused – and healthier and happier in the bargain.
July 2020 #5 – Playtime with Spotlight & Calf!
We moored Blue Parrot on the dock with her nose toward shore. At low tide with a NW wind blowing us towards moored boats in shallow water it’s a bit tricky getting off. We time for a gust to blow Blue P off the dock and pull a 270° turn to head out into Evans Bay. The NW wind sweeps across low terrain on Read Island from Hoskyns Channel, Johnson Strait and Bute Inlet. White caps on the crests of short steep waves rile up the mouth of the bay. Wind and waves blow us around the point all the way into Burdwood Bay.
Terry assesses the possibility of an anchorage for later tonight. “Looks good at low tide here. I think we’ll be OK. Let’s head out.” Blue P angles across the frothing mouth of Evans Bay to the Penn Islands. We’re getting ready to raise the sails when the water suddenly flattens and the wind dies. “Typical” Jude mutters as another attempt to sail is foiled yet again.
All thoughts of sailing evaporate as we spot 2 humpies close to the shore of the middle Penn. They’re moving slowly, making their way around the outside island closest to Cortes. “Sleeping” Terry notes wryly. He notices one of the whale watching boats emerging from Whale Passage and reports the whales. We decide to move a little closer when “What was that? Up ahead – a breach – towards Von Donnop” We hear the WHHOOMP of WHALE hitting Water. “Let’s Go!” Jude steers Blue P over as the whale watchers speed past.
We approach slowly and cut the engine “Is that a baby?” Terry wonders “Yes! A Mom and Calf! Look! The baby is breaching – she can’t quite make it all the way out of the water” —–“Is this a good position?” Jude calls to Terry who is perched precariously on Blue P’s bow manouvering carefully around the furled jib.
“WHOAH!” Mom is tail lobbing. Half her body is up out of the water. Baby is so close it looks as if Mom is going to land on top of herm – but she doesn’t. “Looks like they’re playing” Terry shouts during a brief lull in activity. He’s performing some fancy footwork to keep the whales in focus as they circle around Blue P at about 100 meters. Their play is so exuberant and Baby’s ingenue breaches are so adorable. Then Mom BREACHES – WHHHHUUMMMPPPP! The SIZE of HER!! There are no words equal to the AWESOMENESS of a 40 TON WHALE leaping clear out of the ocean into the air. “Sky Hopping” as our friend Martha thought it was called – A much better description of defying gravity!
So special to finally witness a Mom and Calf playing together like this. We are so juiced! We’ve waited 5 years for this moment – and to capture it on film so we can share it with you was worth every minute of boredom and discomfort.
Mom and Calf are moving north. They’re getting farther away as the wind blows Blue P south. Then “Looks like playtime is over. They seem to be resting now”. Terry observes. “Heads up!” Jude calls. She swings Blue P around in the direction of a nearby cove where half a dozen boats are congregating. “There are a couple of whales over there. Maybe they’ve finished sleeping” We hang around with them for a while but they’re not interested in people. They dive and easily give us all the slip.
Meanwhile it’s getting pretty windy so we decide to head back towards our evening anchorage. Evans Bay has once again erupted in white caps and heavy winds. We angle across the waves, navigating around another whale who is also crossing. “Happy sailing friend”
There are 2 other sailboats already anchored in Burdwood Bay so anchoring is a bit tight. But it’s protected from the NW waves and the gusts will blow us off shore not towards the other boats, so we settle in for the night.
July 2020 #6 – Raza and Harlequin the Humpback Acrobats
It’s morning in Burdwood Bay and we’re up and away before the tide drops too low. “Let’s head NE again.” I suggest “we can sail to the Penns and check for blows as we go.” I unfurl the jib and we manage a short sail before the breeze completely dies (typical) as we reach the Penn Islands.
We float around scanning the scene but don’t find any whales. Terry notices a whale watching boat speeding out of Whale Passage towards Calm Channel. “Hey! I think they’ve stopped. They’ve probably found a whale” he says “Let’s go over there. I’ll get my camera” I fire up the engine. We head over and start to line up beside the whale watch boat when the 2 whales begin to jump. “They’re coming our way Terry” I yell “I’ll have to get out of the way!”
“A breach! Another breach! A double breach! They’re too close! I need my wide angle lens!” Terry yells. ” Shit! I can’t get them both in the frame. I’m just guessing where they’re going to come up. I focus on this whale and that whale breaches. I don’t know where to point the camera!” I find the wide angle lens sitting in the cockpit and run to the bow to hand it to Terry. Then I run back to the tiller to steer the boat away from the whales who are getting closer. “Why is there always wind when we’re with the whales?” I opine. Blue P skims over the waves past the boats on the other side of the whales. Meanwhile the pair begin to fin slap. They execute a few more breath-taking breaches which we miss because Blue Parrot has sailed away from the action.
This is a perpetual problem with the Parrot ship. She’s a sailboat and the wind moves her even without sails up. And she has a lot of inertia when she’s moving unlike a runabout which will simply stop when you kill the motor. Add to that the joy of an engine with no true reverse. She’s not the easiest vessel to control. With lots of other boats around and whales close to us all my attention has to be on the helm. This means I don’t have time to get my hydrophone into the water to record any possible vocalizing between the whales. I also have a skookum stereo mic onboard but all this takes about 5 minutes to set up. We really need a larger boat with a dedicated skipper to be in charge of it. (This will not be news to anyone who’s been following these blogs.)
“Terry, I’m going to have to turn the boat with the wind. You’ll have to move to the other side.” Poor Ter. It’s hard enough to find a place on Blue P to shoot video that’s not obstructed by shrouds, stays, mast, boom, life lines or other hardware blocking the camara’s view. Then there’s all the buttons and wheels on the GH5 which all have different functions depending on the various positions of each one. It’s too easy to hit one accidentally and shut off something or turn on something else you didn’t intend to turn on – or turn record off altogether – especially if you’re 6’4″ and have big hands. And that’s even before you have to decide which lens to use – telephoto or wide angle? Whales don’t stay in one place for long. And, if there’s more than one which whale is going to jump? It’s hard to fit a bunch of whales into one frame. After pondering on that controlling a tender sailboat seems easy in comparison.
Meanwhile Terry observes something on the back of one of the whales “Are those propellor marks?” he asks. He’s peering through the camera. As the whales settle down Blue P drifts over to one of the whale watching boats. The skipper is Nick. He’s an expert guide who has been on the water for years and can identify most of the humpbacks and orcas individually. “The one with the propellor wounds on her back is Raza” Nick tells us. Later we learn that the other whale may be Harlequin.
Meanwhile half a dozen recreational boaters who have gathered to watch the show disperse into the channel. “Let’s try anchoring in Von Donnop tonight – we’re already here” Terry suggests. “It’s Saturday night – do you think there’ll be space?” I ask “There’s lots of anchoring space all through there ” Terry responds. “OK, but I need a swim first. I’m so hot. I’m going to head into the calmer water and jump off the bubble boat.”
40 minutes later I finally exit the chop of crisscrossing currents to find calmer water. Since the evening wind will probably come up again soon I jump into the ocean for quick frigid dip “EEEEEE!”. I haul out to let Terry have a turn. Terry perches on the edge of the bubble boat gingerly splashing his too HOT skin and ruminating on whether he’s up to getting in when “Hey Ter, there’s 2 whales coming up the channel. They’re headed this way – maybe 150 meters.”
PLOP! He’s in like Flynn! – no hesitation – splashing his long arms like fins to attract the whales. “Take a photo of me with the whales” Terry yells moistly. I drop into the cabin and grab the camera – but the whales aren’t cooperating. They just keep on truckin’ past us up the channel. Oh well. We amuse ourselves shooting video of Terry fin slapping and being a whale in the water with the magnificent mountains as backdrop.
Then the wind comes up and it’s a wild ride into Von Donnop with the wind on our heels.
May 2020 #2 – First Humpback Whale Sail
It’s finally our first cruise of the season. Our inflatable dinghy is held together mostly by glue, epoxy, 5200 and lots of repair hours. We offer prayers to the gods of small appliances “Please let him make it through another whale season.” SV Blue Parrot is so far in pretty good shape. Unfortunately she hasn’t grown any over the Winter – still too small for Giant Terry.
We enjoy a few days at anchor in a beautiful bay to relax and get back into the rhythm of weather and tides. There is no cell or internet service in the Bay. Our VHF radio intermittently transmits weather statements from Environment Canada. Reception depends on Blue P’s position in the arc of her swing around her anchor.
We weigh anchor in light rain showers. An occasional breakthrough of sunrays through rainclouds plays rainbow prisms over dark mountains with snowy peaks. A report of a humpback whale near Cortes Reef comes in. “Let’s Go!” We’re on our way through Baker Passage when Terry shouts “Orca! They’re coming this way. 3, no 4 of them. I’ll get my camera.” He hands off the tiller to me after I’ve quickly grabbed my hydrophone gear. ”
They’re traveling really fast.” Terry announces. “They’re through the passage. Maybe they’re going to the rubbing beach – no they’re headed across to the mainland” I drop the hydrophone anyway in case the orca are vocalizing or communicating with others we can’t see. I listen. “Nada. Maybe they’re hunting and they’re in stealth mode. They’re obviously mammal eaters” (Transient Biggs orca). I reel in the hydrophone.
Nearby, gulls are crying and swooping down in a frenzy! Guillemots and loons are also diving underwater at the same place. As we approach, bald eagles start flying in and grabbing fish from the surface. A Bait Ball is happening!! Herring or anchovy are being forced to the surface by salmon below them, making them available to aerial predators. S-c-r-e-e-e-e-e-ching eagle cries join with the gulls’ screaming in a cacophony of sound matching their chaotic flying and swooping. Soon there are a couple dozen eagles vying for fish and more keep coming! Where do they come from? Are there that many within sight of the bait ball? Or do they hear the sounds of birds or do they call each other, or . . .? Mysteries abound and every day in the natural world brings more questions we want to answer! Questions, questions, questions . . . always more and more!
There is a light SW breeze and the tide is with us so we float off Marina Island for a while and duck into the cabin to get out of the now intense midday sun. Terry sticks his head out for a quick check just as 2 humpback whales breach off Francisco Pt. We fire up Lazarus (our WWII engine) and beetle over as fast as we can (4.85 knots/hr) while the whales breach and fin slap. 20 minutes later we arrive on the scene and carefully line up with the 2 recreational boats who have been enjoying the show. But the whales are finished being active. They proceed with their usual mode of activity when they are close to us – they go to sleep!
“OOOO Whale Breath” Terry groans as a piquant perfume of rotting fish with sulphurous accents wafts over us. But I am in whale heaven. I just love to BE around them even when they’re sleeping. Terry starts to talk about the challenges of shooting good video of whales from a sailboat. One of the whales gives a single gentle tail slap and both whales swim away.
Did we disturb them by talking? it’s so hard to know what that tail slap meant. [see Humpback Body Language Blog April 2020] We don’t follow them since they obviously left us.
The light SW daytime breeze is a harbinger of summer winds. We hoist the sails and sail to Drew Harbour on a broad reach. Sutil Channel is covid 19 quiet. There aren’t the usual fishing and tourist boats around. Our ears perk up – a breath. It’s another humpback whale – a smaller juvenile – and s/he is snoozing mid-channel. We sail serenely on.
Drew Harbour is a shocker. We round the end of the spit to find flotillas of flotsam and floating logs filling the anchorage. “It looks like a boom broke up in here” i say. We weave our way to our favourite anchorage and set the anchor just as the tide starts to ebb and the wind switches to NW 10 – 20 knots. Just in time! Sure cools off a hot day though.
May 2020 #1 – Lockdowns!
There are many kinds of lockdowns. Some are physical. Others are emotional, psychological, spiritual. Covid 19 started as a physical lockdown. But the lockdown itself is affecting the mental, emotional and even spiritual health of the human global population. Prisons of any kind, even the kindest kind will do that.
The economic restrictions have killed the usual May tourist rush here on the Salish Sea. With the Canada/US border closed to non-essential traffic yachts from Seattle are barred. Vancouver area boaters are mostly staying away although a few have been sneaking into anchorages in Desolation Sound and the Discovery Islands. Fuel and pump outs can be accessed from some marinas but most limit traffic “from away” to the dock area – no mixing with the locals.
With tourists banned whale watching companies are advertising a shut down until Summer. However, some of the captains are still out on the water doing water taxi or other work. So they are sending reports to the network of any orcas, dolphins and whales that they come across. And some intrepid nature-loving souls are just hanging out with any cetaceans they find.
I’ve been anxious to get back on the water with the whales since April. The long winter and extended virus season have been opportunities for more research about other species of whales. All live intriguing and mysterious lives that we humans know so little about. I’ve also been corresponding with Jim Darling, co-founder of Whale Trust in Hawaii and an expert bioacoustician. I sent Jim the whalesong files that I recorded in November of 2019. Jim has done some fascinating research into the meaning of humpback whalesong, its function in humpback culture and its relationship to regional populations and migrations. The revelations of Jim’s research will help us to understand the role of whalesong in humpback relationships amongst males (who are the singers) and between males and females (who are choosing mates).
Jude and Terry find that the old law within the science hierarchy about not attributing emotional, problem solving and aesthetic capacity to any animal except homo sapiens still seems to be operating. Research projects which are granted funding follow the strict rules and metrics of stated factors and vectors with observations fitted into those boxes. This approach has proven very useful for specific information like population numbers, genetic tracing, food sources etc. But it is only one approach and has limitations. Other ways of gathering information ie: traditional indigenous knowledge and stories are barely acknowledged and not credited. Even in private conversation many scientists rarely let on that they might wander and ponder outside of their proposed Science-dictated hypotheses. We find this sad – mostly sad for the researchers who can’t explore their emotional and even spiritual connection to the beings they spend so much time studying.
Anyway, people have been observing the returning humpback whales mostly in Discovery Passage and venturing around Cape Mudge into Sutil Channel. It’s time to venture out for our first whale cruise of the season!
April 2020 – Humpback Body Language
We humans love the animals who live with us. And they love us too. Over milennia we have learned how to communicate with each other by reading each others body language. Because we are all binary models ie: 2 arms, 2 legs, 2 brain hemispheres, 2 ears etc. a lot of our musculo-skeletal responses to stimuli are similar. We “raise our hackles” and snarl when angry, we whimper and cower when afraid. Humans have learned to read tails and our animal friends can read human eye and hand movements. We recognize each others’ voices and faces and scents. Wild animals who live close to humans have also learned to read us. Racoons, birds who nest and feed near us, squirrels, mice and rats – even house spiders I am trying to avoid while vacuuming are aware of my movements and what they are signaling.
Fish can be extremely curious. Divers love to play with friendly octopuses, seals, manta rays and dolphins. Divers keep returning for more encounters, sometimes with gifts of food or toys.
But what about whales? They are mammals like us with symetrical brains and limbs BUT -and that’s a BIG but – their scale is Super Sized. The medium through which whales perceive the universe is water so their senses are tuned to that environment and not as acute in air. Humans need special aparatus and training to spend any time in a whale’s world other than at the surface of the ocean. Our eyes and ears are not evolved for the liquid environment so we need to surround them with air in order to focus light and sound. So how can we become familiar with whale body language if we only see the 10% of their body that breaks the surface and can’t correlate their vocalizations with their actions?
Biologist and researcher Denise Hertzing has spent over 3 decades studying wild spotted and bottlenose dolphins in one bay in the Bahamas. The water is warm and clear which makes it possible for Denise and her team to actually interact with the dolphins in their world. Because she can be in the same environment as the dolphins she has learned their body language. She understands the meaning of many of their calls and can relate some of their behaviour with their vocalizations. Her team has even adapted dolphin body language to the human body. The Team can approximate some of the gestures and expressions dolphins use. Instead of rubbing fins with friends as dolphins do the humans rub elbows. Denise knows the pod as individuals and has become very friendly with a few of the females. They know she is in charge of her team and will show their disaproval directly to Denise if one of her team doesn’t follow dolphin protocol. The dolphins choose whether they want to interact with the humans, coming and going as they please. Denise is one of the few biologists who openly studies interspecies communication and the possibility of humans and cetaceans learning each others’ languages.
But what about whales? What does it mean when a whale slaps their tail on the water? In beaver language a tail slap signals a startled reaction or pissed off response and generally means “take off, eh?” In humpback whales Terry and I have observed that a tail slap can mean anything from “Hey, give me your attention” if soft and gentle to a warning or reprimand if hard and explosive. We’ve seen tail slaps when humpback whales are playing with sea lions and also when the whales seem to be feeding so maybe they use tail lobs to stun and disorient fish.
I am curious to know whether many body language gestures have similar meanings and/or intentions throughout the cetacean family tree – a question I will ask the research folks and the whale watching guides who have the most opportunities to observe wild cetaceans in the water.
