This year, on my annual Bubble-netting Humpbacks workshop, I put some time and effort into recording video. My Canon R5ii is incredibly capable at video, and here I recorded at a whopping 180 frames per second, which provides for great slow-motion video.

The sounds were recorded using a hydrophone and is the audio from a single bubble-netting lunge. Listen carefully and you can hear multiple whales, and several different types of calls. The piercing whistle is their “feeding call” it’s used to organize the pod and may also distress and confuse the schools of herring the whales are hunting. You can also hear, deeper rumbling notes that serve as communication.

We’ve had moments like these on every trip I’ve led to watch this phenomenon. Care to join me? It’s yearly trip in late March. Check it out!
