A juvenile humpback whale entangled in more than 200 feet of rope and then freed earlier this month has been spotted off Galiano Island in British Columbia, prompting cautious relief among biologists who are monitoring the whale’s recovery. The whale, named Starry Knight, was seen by whale watchers last Friday, and was breaching and appeared […]

Follow the herring: Why sea lions have been calling Shilshole Marina home
For the past three springs, Shilshole Bay Marina has been contending with droves of California visitors occupying their guest boater moorages––California sea lions that is. To Shelby Allman, Port of Seattle Harbor Operations Supervisor, it seemed like the furry visitors arrived almost overnight. By mid-May nearly 120 animals had hauled themselves onto five “finger” docks […]

Research and whale watching enhanced with artificial intelligence to identify individual orcas
When out on Puget Sound with killer whale experts, I’m often impressed by how quickly such folks can identify individual whales by name or number, even when a group of orcas is swimming a fair distance away. I can’t begin to do that, because I have never studied the catalogs of dorsal fins and markings […]

Publish or perish the thought: Orcas, seals, and a curious scientist
In 2022, more than three million scientific papers were published in about thirty thousand journals. This represented something like a 9% increase over the year before, and a 47% increase since 2016. “Academic publishing has a problem,” wrote Mark A. Hanson, the biologist at the University of Exeter who compiled these figures. “The last few […]

Southern resident orca numbers decline during census year; Bigg’s orcas continue to expand
Although the official census report won’t be submitted for a couple months, at least two southern resident killer whales have died over the past year, with one of them being a little more than a month old. This unnamed, deceased baby, designated J60, was the only new birth reported among the endangered orca population in […]

All killer whales will remain one species — for now, according to marine mammal committee
A formal proposal to designate resident and Bigg’s killer whales as separate species has been rejected by a committee widely recognized as the authority in naming new marine mammal species. The proposal for new orca species, put forth by a team of geneticists and marine mammal biologists, was based on the distinct genetic, physical and […]

Decision time approaches for two new orca species, as other issues bring new questions
Killer whales worldwide are currently identified as a single species, Orcinus orca. But two new species of orca, representing thousands of whales in the North Pacific, could be added to the scientific nomenclature within the next month. Evidence supporting the new species, which I described in the Encyclopedia of Puget Sound, has been submitted for […]

A no-death census year for Puget Sound’s orcas, with observations about a recent shift to more female births
For the first time since Census Year 1993, no deaths were reported this year among the Southern Resident killer whales, which frequent Puget Sound, according to the official census report. Two new births were reported among the whales, increasing the population from 73 to 75. I would also like to share some potentially hopeful information […]

Two new baby orcas with no deaths over the past year could make for a remarkable census
This year’s census for the Southern Resident killer whales apparently will document two new calves but no deaths for the 12-month period ending July 1. According to my unconfirmed records, this will be the first time in nearly 30 years that no deaths will be reported in the annual census update. Consequently, the overall population […]

Prey and predators create varying life-or-death conditions for salmon, as shown with Atlantis model
This article is the latest in a series about computer models and their uses within the Puget Sound ecosystem. As scientists uncover more and more information about a particular ecosystem, computer modelers are often eager to put that raw data to good use in complex models tuned to local conditions. One highly acclaimed model, called […]
