November 2019 #4 The Pinnacles of Whalesong

Nov 6th dawns another frigid morning. While our tea kettle attempts a few tunes of its own Terry downloads video from the camera. Jude is programming her mixer/recorder while listening for whales on the hydrophone. “Terry – I hear something –  it definitely sounds like singing – not close. Let’s head out. I’ll keep the hydrophone down and keep listening. We may be able to locate them”

We head the Parrot ship SW in the direction of Vancouver Island – to The Pinnacles. That’s where, yesterday, the golden light of the setting sun backlit heart-shaped blows of 6 – 10 humpback whales. Their dark backs appeared as tiny black crescents breaking the surface 2km SW of Blue Parrot.

The Pinnacles is a rock formation which rises sharply from the ocean floor at 600ft up to 70 ft below the water’s surface. Fish like to congregate here and so do all the critters who eat them including humans.  As we motor closer Jude is listening for increasing volume of whalesong. “Sounds like we’re going in the right direction. Do you see anybody” “Nobody yet” Terry answers “Let me know when you want to stop”

During mid-day there is a break in service on the Comox-Powell River and Texada-Powell River ferries as their crews change shifts. Happily it’s break time now. The silence is heavenly. These are the clearest songs Jude has been able to record. Subtle nuances and inflections which had been obscured by boat noise on the previous recordings are now clearly audible. “You’ve got to hear this Terry! I think there are 2 whales – 1 farther away” An enraptured Jude holds out the headphones “I’m going to get the speaker so we can both listen.”  Jude plugs in the speaker and whalesong pours into the air.

We listen: The sounds are so awesome – so expressive. It’s not possible to listen without being moved – enthralled by the ranges and timbres of their voices.

They grunt, groan, whoop and whistle. There is even a knocking percussive sound. How are they making that sound?

What are they singing about? What emotions are they expressing?  Do groups of males get together to sing in unison? Are these whales singing together?  The 2 whales don’t seem to be singing the same part of the song. Are they friends? Do whales sing over each other like birds do when they are proclaiming their territory? – So many questions but mostly exhilaration and awe.

Aerial whalesong might be what attracts a curious young seal to Blue Parrot. Seal circles our ship, peering into the cockpit at us. S/he dives underwater and we hear whiskers snuffling against the hydrophone “Hey! Get off of there!” Jude yells into the water. Up comes seal but s/he doesn’t leave. S/he stays with us checking out our dinghy – looking and looking. “Maybe s/he’s a seal scientist or engineer and s/he’s calculating the logistics of how we could be hiding a humpback whale in the cockpit of our little boat!” Terry laughs. Jude holds the speaker out where seal can see it and turns it off and on to demonstrate to seal where the whalesong is coming from. Seal disappears underwater and then surfaces again.  The whalesong must be very loud underwater. And the same song is coming from our boat – probably delayed by a few seconds. It must be a profound puzzle for a curious seal.

 

Could this curious seal be the one under our boat listening to the whalesong?

Eventually seal departs. But the blessed reprieve from boat noise is soon blasted apart by the engines of several tugs towing heavily loaded barges northward up the Strait. The bass throbbing of those engines chugs on and on for hours.

After 2 1/2 hours the whales seem to have stopped singing. We scan the sea looking for blows or surfacing whales. “A BREACH” Terry yells as one whale launches himself out of the water 500m away. Another whale is with him but we aren’t close enough for ID. “Of course I don’t have my camera!” Terry mutters. And of course the whales swim off to the west – away from us. On these shorter days we have to head back to the anchorage before the light fades. So we do.

Tomorrow is another day.
