Sitka, Alaska, boasts one of nature’s most spectacular phenomena—humpback whale bubble-net feeding. This awe-inspiring display of marine ingenuity draws visitors from around the globe. And Coastal Tours Sitka offers a front-row seat to this mesmerizing event. Humpback whales are renowned for their intelligence and cooperative feeding behaviors, but bubble-net feeding is a particularly extraordinary spectacle. It occurs most notably in early spring months in the waters around Sitka.
What IS it: Bubblenet Feeding?
Humpback whales typically feed by lunging through schools of fish and engulfing them in massive mouths lined with baleen plates. However, the unique technique of bubble-net feeding takes collaboration among a group of whales.

The process begins when a lead whale emits a stream of bubbles in a circular pattern, creating a vertical wall beneath the surface. This ingenious strategy corrals and confuses schools of small fish into a concentrated mass. The whales then swim through the bubble net with their mouths wide open, swallowing the trapped prey in a coordinated effort. It’s a breathtaking ballet of nature that showcases the intelligence and teamwork of these magnificent marine mammals.
