Reports in from Pacific Whale Watch Association that whale sightings were up was reported in The Canadian press, (CBC), as good news. It is, in totality of sightings for Biggs and humpbacks. But if you read the details, you find that Southern Resident Orcas sightings are actually down. Let’s take what we can of the positive but not be fooled into thinking we have turned around the issue of local residents. As mentioned in the article, the Biggs eat seals and sea lions, which have been overpopulating the area and eating vast amounts of food that competes with the resident southerns. (another way to think of this is that because we have depleted the salmon runs there are fewer fish to feed all the mammals that eat them). This may help balance out the food chain, but we won’t know for a number of years.
… it’s a different story for the endangered Southern Resident whales — the other principal killer whale found in the region — as their sightings dropped to a record low last year. The salmon-eating mammals were documented on just 103 days, or 28 per cent of the year.https://www.cbc.ca/news/canada/british-columbia/record-whale-sightings-2021-1.6311282
