Month: September 2018

September 2018 – Puffer Pigs

Well, it wasn’t a good month for hanging out with humpbacks but we did encounter more delightful harbour porpoises, affectionately named “puffer pigs” than we’ve ever seen before. We were anchored in one of our favourite calm weather spots close to ‘Red Pepper’. The sloop is adorned with a 200Watt solar panel to power her electric motor. Ken and Pat, her crew,  are retired and not in a hurry to get anywhere in particular.  When they aren’t sailing their 35ft red-hulled Erickson sailboat they can motor all day at 3 knots and fully recharge their batteries at the same time. We make a wish that electric motors will soon become affordable for your average low income sailor.

In the morning Terry saw a couple of blows further south so we headed that way. The sky was blue, the mountain vistas spectacular – but no whales appeared – so we floated on a silk smooth sunlit sea for hours. As sunset coloured the sky we followed leaping herring into Blubber Bay on Texada Island, hopeful that some humpbacks would discover the herring too. After anchoring we settled in for a peaceful night.

The moon is bright and the sea still calm when we get up to check the anchor line at 2am. “It’s a perfect night to drop the hydrophone” Jude enthuses. Before I can move: Pchooo! “Was that a blow?” Pchooo! “Terry, there’s a whale out there.”  “Only one?” “Yes, s/he must have found those herring.” The whale is not really close so I drop the hydrophone to listen underwater. What a cacophony! We’re close to shore and the hydrophone hangs close to bottom where  shrimp crackle, barnacles creak, fish grunt, seals burp and pilings rub and groan. It surely is noisy in the intertidal zone. I can’t identify half of these intriguing sounds. They are so loud that I can’t hear any whale noises if there are any. We listen to the whale breathing above the water just outside the bay. But soon a diesel engine barrels into the bay drowning out all other sound above and under the water. Oh well. We plan to get up early to check whether our whale is still hanging around.

And there s/he is the next morning – intently shallow feeding just outside the bay. We float around watching herm for a while. As we float a motorboat zooms towards us headed right for the area where whale is feeding. I call on the VHF radio to let them know there is a whale in the area and they slow down.

One of our friendly Powell River whale spotters with a scope on her deck calls us to let us know that there are orcas in Blubber Bay. We have been so engaged with our humpback friend that we didn’t notice them but now we see 6 orcas racing out of the bay. They are beauties – one male with a very long dorsal fin. I struggle to get the hydrophone back in the water but don’t hear any communications. Maybe they are in stealth mode – mammal eaters hunting seals or sea lions. We watch them disappear into the distance and notice the incoming clouds. “Let’s stay ahead of the rain” I suggest “Do you see the Grant’s Reef buoy?” “Depth is 40 ft, 35, 23, 18” Terry reads the sounder as we approach the shallow reefs. They must be full of fish because a carpet of loons, murres, grebes and gulls float over them. 3 humpback whales troll the deeper water nearby. And here are a dozen harbour porpoises popping up for a puff of breath and submerging to feed together. What a sight! We’ve never seen more than 2 or 3 together so this is a treat.

Rain clouds are catching up to us as another sailboat motors across our bow towards the shallow passage between Savary and Hernando Islands. I call him on the radio and ask if we can follow him through. “Sure” he says. So we do – cruising through the shoals and rocks as our 10ft shallow alarm sounds more than once.

Good thing we’re making passage on a 9ft tide.

2018 Sea of Whales

2018 SEA of WHALES – INTRO

This year was finally the year we’d been working towards. After years of setbacks, injuries etc. we finally got to meet and hang out with Grey whales in Baja, Mexico and Humpback whales in the Salish Sea. They were very different experiences but the following are a couple of stories with observations about human interactions with our large aquatic relations.

Eye to I

Terry (the Amphibiographer) and I were off of Powell River in our 27ft sailboat. There was no wind so we were motoring back towards the harbour at about 4 knots. Suddenly we saw what looked to be the butt end of a large deadhead floating in the water about 100m ahead. Hitting one of these can spell disaster for a boat and I was on the tiller.

“Do you think it moved?” I asked Terry who was at the

bow peering through binoculars to get a better look.

“It’s an elephant seal!” he exclaimed, “See the nose?”

“An elephant seal?” As the head turned I saw that unmistakable trunk-like shnozz come into view. I slowed down instantly and angled sharply to port (left). But our friend didn’t seem to be too fussed. After surveying the view he slowly submerged and disappeared.

We were past him by this time so we looked back just in time to see a humpback whale breach about 300m behind us. I executed a 180 degree turn hoping we would get to witness some playful exuberant humpback acrobatics. Whale breached a few more times but stopped when we were within 150 metres. I slipped the motor into neutral so Whale would know exactly where our boat was and Terry swung below to retrieve the video camera. Then we waited. And waited.

About 10 minutes later “PCHOOOOO!” A blow about 50m from our boat! An arc of dark whaleback surfaced and began to circle around us. I killed the motor since obviously Whale knew we were there. Was Whale curious? I decided to try to communicate with Whale. The closest I can get to mimicking whale language is to play my didjeridoo. My partner can synthesize a mean didjeridoo with his resonant baritone voice. So the two of us began a duet, a whale serenade.

Whale didn’t talk back to us – or maybe Whale did but we couldn’t hear it above the water. But Whale did move closer to the boat – still circling slowly. We drifted together like this for a while – no pyrotechnics, just meditative mellow breathing, didjeridooing and hanging out together. It was magical!

Then Whale took a breath and submerged into a sleek shallow dive from 25m behind our boat, under the length of it to emerge about 7m off the bow! Since Whale was one and a half times the length of our boat this took a few seconds. We were so surprised we jumped, clattered and banged our recording gear as we rushed to video our friend, who then leisurely swam off leaving us breathless.

I have since learned that whales avoid banging and thumping coming from the hull of a boat so that might have chased our friend away. I have also learned, from time spent among the grey whales in Baja, Mexico, that if whales want to interact with you, they will come to you. There is never any need to chase them. A boat that is floating in the water with enthusiastic people onboard can be a source of entertainment for our large friends. It can be a toy to play with, an ecstatic audience for athletic performances, willing volunteers for their teasing tricks like surprise blow hole showers, and even useful for a good back scratch.

The whales who came to visit us in our little boats had complete control of the interactions. From as young as 6 weeks their physical skill and coordination in the water was amazing. They teased us, made us squeal with delight and only stayed with us as long as they wanted. See ‘Baja Grey Whales’ Blog

When a whale rolls on her/his side to make eye contact with you – conscious being to conscious being – you know you have met a relation.

2018-August – Humpback Whales Visit Us

My Mom was fascinated by the stories Terry and I told her about whales. She loved to hear about their curiousity and intellegence; how the grey whales enjoyed teasing the tourists in Baja and how the humpbacks here seemed be attracted to the sounds of the didjeridoo. Mom, Chayashi, died in May of this year from dementia. But even in advanced stages of dementia there were lucid moments during which hearing about whales would put a smile on her face. With all of the Mom care this year and the ongoing tasks that need to be done after a loved one dies we didn’t get out on the water until August.

We made the most of our abbreviated time out in SV Blue Parrot. Our complicated methodology was to sail or motor to the general area where we’d seen humpbacks feeding or traveling and hang around waiting for whales. Whenever we shut off the engine I would drop my hydrophone (underwater microphone) over the side of Blue Parrot to listen to the sounds underwater through headphones. Sound travels 5 times faster in water than in air so I could hear the bugle-like inbreath of distant humpbacks through my hydrophone before the sound traveled to me above the water. Very cool.

This video shows what happened when 2 curious Humpbacks whales decided to visit us twice in the same afternoon. We were drifting with our engine off at least 200 metres away from them while they were feeding. It was their clear choice to visit us.


The Amphibiographer’s Secrets to Enjoying Awesome Whale Encounters: It’s vital to respect these wondrous beings, not to chase, annoy, or disturb them while they are feeding or sleeping at the surface. Slow down in known whale feeding areas and be aware so you don’t run over one. If you see a blow slow down, there may be more around. If they approach you, stop moving, shut off your engine and enjoy the encounter until they leave you.

Whales have an enormous hearing capacity which is very useful over their huge migration range to stay in contact with each other. In their northern or southern feeding grounds they travel through water that is full of plankton and very murky. They depend on sound to communicate and to find their way underwater.

Humans hear sound frequencies from 20Herz to 20,000Herz. But long distance whale communications can be lower than 10Herz and travel thousands of kilometers. When orca, dolphins or porpoises are echolocating they produce a barrage of very loud staccato blips or clicks at frequencies higher than 100,000herz . Some research suggests that baleen whales like humpbacks may echolocate using low frequency sonar but they do not have the very high frequency capability of porpoises or dolphins or even the toothed whales. There doesn’t seem to be definitive research that nails down the range of frequencies humpback whales can hear. Happily we humans can thrill to their intricate songs because Humpbacks sing predominantly in the hearing range of humans.

Here is a fascinating and playful introduction to hearing ranges in familiar animals.

I would love to know whether the humpbacks that Terry and I were serenading in this video sang back to us underwater. I will need a spectrograph that maps audio frequencies to interface with my hydrophone in order to discover whether they are vocalizing outside our human audible range. Stay tuned to find out!
