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:

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.
