Nature abhors a vacuum. And species go, if they are able, to where the food is.
To the untrained eye, the orcas socializing in the Salish Sea on Friday could have been the resident whales that many Islanders know and love. But those who know, like Stephen Pincock, owner of Ocean EcoVenture in the Cowichan Valley, recognize the significance of seeing Bigg’s orcas – slightly larger, mammal-eating killer whales – in the endangered Southern residents’ long-time habitat. “We’ve seen [resident orcas] shift to the outer coast more…because there’s more salmon out there for them than in the inner waterways,” Pincock said. “It’s kind of opened the door for the mammal-eaters to come in and take their place.” Nina Grossman reports.
