Playful Pod

 

Perfectly ‘synched’, these Pacific White-Sided Dolphins (Lagenorhynchus oblquidens) gracefully paced our boat as we motored across Blackfish Sound near Port McNeil on Vancouver Island’s rugged north coast. These playful and social marine mammals are a favorite in British Columbia’s Emerald Sea, and encounters such as this are among the many reasons I keep coming back to dive the rich, current swept islands of the region. During autumn large numbers of these dolphins arrive to feed on the schools of herring and pilchards, or Pacific sardine, that have returned to these fertile waters after heavy fishing all but cleaned them out in the early twentieth century. The dolphins’ reappearance here is likely because this prime food source has made a comeback. In winter and spring they seem to split into smaller groups to feed in the fiords and inside waters.

Several hundreds of dolphins can be swimming together and if you’re lucky enough to encounter them on such an occasion it’s as though the waters of the Sound have literally come alive. They can often be observed playfully harassing other larger marine mammals the likes of Humpback Whales and resident Killer Whales, also in the ‘hood during summer and autumn. The dolphins somehow know the difference between the resident fish-eating orcas and the transient orcas that will feed on dolphins and seals. An important distinction! More recently they’ve been showing up in the Strait of Georgia and Howe Sound near Vancouver. In different locales on the coast archaeologists have found their bones while searching through ancient ‘middens’ of long ago first nations people, evidence that they have inhabited these waters for generations, most likely millennia.
